<para>
This document describes the use of mondo and mindi tools to realize disaster recovery backup of your systems. It provides information on installation, backup and restore modes, hardware and software requirements, and answers to some frequently asked questions.
The goals are to offer a general view of the functions and their best usages.
Mondo Rescue is a Disaster Recovery Solution which allows you
to effortlessly backup and interactively restore Linux, Windows and
other supported filesystem partitions to/from CD/DVD-+R/RW media, tape,
NFS, ... and Mindi Linux provides the bootable emergency restore
media which Mondo uses at boot-time.

<title>Purpose / Scope of this Guide</title>

<para>
This HOWTO serves to help people get started with using
mondo/mindi as way to backup/restore their system. This is a work
constantly evolving. It was started by Hugo Rabson and has
since been worked upon by a number of people. See the
'<ulink url="&WWWB;about.shtml#devteam">About</ulink>' web
page for a list of members of the development team.</para>

<para>There are many ways to contribute to the Linux movement
without actually writing code. One of the most important is writing
documentation, allowing each person to share their knowledge with
thousands of others around the world. This HOWTO is designed to
help you get familiar with how Mondo/Mindi works.</para>

<para>
Opinions expressed here are those of the authors.
Informations are provided in the aim to be useful to the readers.
However, there can't be, through this document, any warranty of any kind
on the way it works on your systems, nor the author could be responsible for any problem caused by the use of these informations.
However, software editors don't garantee you a lot either (re-read the contracts).

and I will try to incorporate them in a next revision or to the &ML;;
e-mail the list at
<ulink url="mailto:mondo-devel@lists.sourceforge.net">mondo-devel@lists.sourceforge.net</ulink>;
tell us what is wrong and how it should be fixed.
Include the section title and recommended changes. Whenever possible, include

Please note that we do our best to help everyone but it is
difficult for us to help you if you do not attach a log file to
your e-mail. Let me say that again - attach your log file to your
e-mail! Thank you. Without it we can't offer
any tangible help because you aren't either. That's what the log

I am also willing to answer general questions on MondoRescue, the best I can.
Before doing so, please read all of the information in this HOWTO, and then send me detailed information about the problem, especially including the logs generated by the tools, or traces obtained (Did I say that already :-].

Choose from the list of supported backup media types. The media you
will use most often are CD/DVD-+R, CD/DVD-+RW, tape, NFS and hard disk. If
you want to backup/restore over a network, choose 'NFS'. If you
want to backup/restore to/from a local partition or if you simply
want to store the ISO images in a local directory until you have
time or facilities to burn them to CD's, choose 'hard disk'. If you
choose 'CD/DVD-+R[W]' or 'tape' then in general your hardware will be
detected and configured for you.

The backup process will now commence. There are some pre-backup
tasks to be carried out first but the backup is essentially
underway. To simplify the backup process, you were asked a series
of questions. Next time, if you like, you could call mondoarchive
with various command-line switches to control its behavior, instead
of answering a series of questions. See the man page for details.

Mondo will make a catalog of all files to be backed up. This may
take up to five minutes. The list of files will be divided into
sets, approximately 4 MB (before compression) of files per set.

Mondo calls Mindi. Mindi generates bootable media image and
auxiliary data disk images which are based on your existing Linux
distribution and filesystem. That way, you can be sure Mondo's
tools will be compatible with your existing filesystems and
binaries: Mondo's tools are your tools. Mindi takes up to five
minutes to run.

Finally, Mondo begins backing up your computer. This process may
take a few minutes or a few hours, depending on how much data you
are archiving, how fast your CPU is, how much RAM you have, and so
on. It will backup your regular files and then your large files
(files larger than approximately 32MB). If you have opted to verify
your backups, Mondo will do that too.

<para>The 'c' means you must be writing to CD-Rs, not CD-RWs (the
latter would require 'w' instead of 'c'). The '4' is the speed of
your CD writer. The string after -I is the path to be backed up.
The '-gF' means you are going to see the pretty yellow-on-blue
screen instead of the boring white-on-black screen. :) It also
means Mondo will not offer to create physical boot media for
you. It is assumed that you are able to boot from the CD which
Mondo has generated.</para>

<para>Note that you have to mount the NFS partition, backup to it,
unmount it, and create a boot CD to allow you to restore from
scratch if necessary. To reassure yourself that you will be able to
restore from the NFS share even if your PC is wiped, please boot
from the Mindi CD and type 'compare'. The on-screen instructions

<para>In this case, we assume Syslinux is incompatible with your
boot media. For some reason, some BIOSes just don't like Syslinux.
If you find this to be the case for your computer, please use '-L'
to force Mondo to use LILO instead of Syslinux as the boot loader
for its media. (NB: This has nothing to do with which boot
loader your hard drive uses.) Also, it is a good habit to specify
your tape streamer with '-d &lt;device&gt;'. You don't usually need
to but it's good to be on the safe side. Some computers call your
tape streamer /dev/osst0, some call it /dev/ftape, ...
Also, depending on the tape streamer model, a tape should be inserted 
in the tape drive before starting mondoarchive, otherwise it may not 
recognize the drive.</para>

<sect1 id="overview-mondorescue">
<title>Mondo Rescue</title>
<para>Mondo Rescue backs up your file system to CD, tape, NFS
(archives stored remotely) or ISO's (archives stored locally).
Mondo uses afio as the backup engine; afio is a well-respected
replacement for tar. In the event of catastrophic data loss, you
may restore some or all of your system, even if your hard drives
are now blank. Mondo Rescue can do a lot of other cool
things:</para>
<itemizedlist>
<listitem>
<para>You can use Mondo to clone an installation of Linux. Just
backup the crucial stuff and exclude /home, /var/log, etc.</para>
</listitem>
<listitem>
<para>You can backup a non-RAID file system and restore it as RAID
including the root partition (if your kernel supports that).</para>
</listitem>
<listitem>
<para>You can backup a system running on one format and restore as
another format.</para>
</listitem>
<listitem>
<para>You can restructure your partitions, e.g. shrink/enlarge,
reassign devices, add hard drives, etc, before you partition and
format your drives. Mondo will restore your data and amend
/etc/lilo.conf and /etc/fstab accordingly.</para>
</listitem>
<listitem>
<para>You can backup Linux/Windows systems, including the boot
sectors. Mondo will make everything right at restore-time.
(However, do run "Scandisk" when you first boot into Windows, just
in case.)</para>
</listitem>
<listitem>
<para>You can use your Mondo backup CD to verify the integrity of
your computer.</para>
</listitem>
</itemizedlist>
<para>Mondo's principal virtue is that it protects you from the
problems that can arise when you reinstall completely from scratch.
If you want to wipe and restore your system every year just as a
matter of 'good practice', Mondo is not for you. However, if you
want to get up and running again in a hurry after someone breaks
into your computer and wipes it (or if you accidentally wipe it
yourself) then Mondo is definitely for you. It will permit you to
roll back to a known-good installation in a very short period of
time, sometimes as little as twenty minutes. Even if you backup
large amounts of data to tape daily and do not want to add yet
another backup regime, please consider backing up the core
filesystem (i.e. everything but the directories containing your
huge database and your prizewinning novel) every month or so, just
in case. You will be glad you did.</para>
<para>What is Mondo not?</para>
<para>Mondo is not an everyday backup program. It is not designed
to replace tar, afio, kbackup, etc. Mondo is designed to make it
possible to recover from scratch if necessary. Tar and afio offer a
quick, convenient way to backup small sets of files, sometimes to
removable media.</para>
</sect1>

<sect1 id="overview-mindi">
<title>Mindi</title>
<para>
Mindi Linux creates a set of boot/root media images
that will let you perform basic system maintenance on your Linux
distro. The principal virtues of Mindi's boot disks are the fact
that they contain your kernel, modules, tools and libraries. You
can ask for additional binaries (or other files) to be included on
the kit. The libraries will be added for you.
</para>
<para>Whichever modules were loaded at backup-time, they are
reloaded at boot-time. So, in theory, you will boot into almost the
same environment as you were in when you backed up. If you want to
add files to your Mindi boot disks, edit '&lt;INSTALLPATH OF
MINDI&gt;/mindi/deplist.txt' and add the files to that list. The
added files and dependencies, will be spread across the data disks
at run-time.
</para>
<para>Mindi makes sure that Mondo has all the tools it needs at
boot-time. Mondo uses fdisk, mkfs, cat, less, more, afio, gzip,
bzip2, your keyboard configuration, your glibc libraries, your
other libraries, your kernel, your modules, ... which is a lot of tools! 
Mindi takes care of all that, so that Mondo can get on with the job of backing
up or restoring your data.
</para>
<para>Mindi is also handy for making boot CDs/disks which stand on
their own. You do not need Mondo. Indeed, if you like, you could
use another backup/restore program with Mindi. Just add it to
Mindi's dependency list (type 'locate deplist.txt' to find it).
Mindi will include your software on its boot CD/disks the next time
you run mindi.
</para>
</sect1>


<sect1 id="overview-linuxbackup">
<title>Linux Backup</title>
<para>Mondo Rescue and Mindi Linux are used primarily as Linux
backup and cloning tools. The fall in prices of CD-RW drives and
writable discs will allow current users to keep good backups and
future users to leverage the cloning capability.</para>
<para>Tape drives are more likely to suit your needs if you run a
larger installation (or have lots of MP3's). Warning! OnStream
drives do not play well with Mondo. I do not know why. It is, in my
opinion, something which OnStream should look into. Mondo uses
fopen(), fread(), fwrite() and fclose() to interact with tape
drives. That works for most drives but some drives just don't like
that.
Also, depending on the tape streamer model, a tape should be inserted 
in the tape drive before starting mondoarchive, otherwise it may not 
recognize the drive.</para>
<para>Mondo Rescue has been tested thousands of times on various computers.
It has worked for them.
Thousands of users testify to Mondo's stability and its ease of
use. However, please test it on your own system before you rely on
it. In fact, do not rely on any software until you have tested it
to see if it performs as expected.</para>

<para>FYI, the subroutines to repartition and reformat your drives
are very stable. If you are a RAID or LVM user, you
might&nbsp;encounter some difficulties when wiping and restoring
from scratch because of the sheer range of filesystem layouts and
the impossibility of testing Mondo on every single one. If you have
trouble, just drop to the command-line and partition/format
manually. Then, call mondorestore, select Interactive Mode, and say
'no' when asked if you want Mondo to partition or format your
drives for you.</para>
<para>You see, even if you have trouble, you still have two hands
and most of the tools you need - lvchange, pvcreate, fdisk, mkraid,
etc. - to do it manually. After you have prepped and formatted your
drives manually (if you have to), just run mondorestore again and
say 'no' when asked if you want to prep or format your drives. What
could be easier?</para>

sector of /dev/hda1 prior to the restore.</para>
<para>Note: if Windows ME/95/98 is not located on /dev/hda1 or

reflect the size and type of the partition. The user may not edit
that partition's size at restore-time (for obvious reasons).</para>

<title>Mondo Rescue and Mindi Linux
History</title>
<para>Mondo Rescue was created in December 1999 by Hugo Rabson as a utility to
clone Linux/Windows installations. Norton Ghost would not do the
job, and his boss wanted to jump on the Linux bandwagon. So, he wrote
a few scripts and shoehorned them into the latest Linux-Mandrake
CD. Since that time, Mondo grew into a disaster recovery suite for
Linux and Windows. Mondo forced him to learn about the kernel, its
initrd initial ramdisk, modules, library dependencies, disk
partitioning, and the myriad differences between the Top 10 Linux
distributions.</para>
<para>The first formal release was made on February 18th, 2000.
Mondo is currently one of the top five Linux backup/restore
programs. Mondo has been compared favorably to ArcServe, Arkeia and
BRU. Although Mondo lacks the more advanced, enterprise-level
features of ArcServe and Arkeia, for workstations and small- to
medium-size servers it is ideal because it is small, fast,
efficient, stable, comes with source code, and is being actively
developed and supported.</para>
<para>
        Since November 2005, Hugo Rabson has tranfered the maintenance 
        of the Mondo Rescue suite to Andree Leidenfrost and Bruno Cornec,
        both previous developers and packagers of the tool since nearly 
        the begining.

        <title>Introduction</title>

<para>
Mondoarchive is designed to run interactively. That's not strictly
 true, if you run mondoarchive without the '-g' switch, it will just
 run. However, there is a problem where media changes are necessary.
 The user must change the media and tell mondoarchive that the change
 has been done. The problem lies in the fact that cron does not allow
 user interaction with a job. If you schedule a mondoarchive job via
 cron, you better be sure it needs only one media. In practical terms,
 this means using tapes or ISOs (if CD-R(W) is your backup medium).
 However, for tape users, there's always the possibility that the
 backup will overflow the tape while for CD-R(W) users, there is the
 added hassle of burning the ISOs in the morning. If your CD_R(W)
 backup routinely occupies more than one media, this is not for you
 (use the ISO option and burn the CDs in the morning). This HOWTO
 addresses the problem by using screen as a wrapper for mondo.

<para>
Mondo users who wish to automate the backup and whose backups
 routinely occupy close to one media are the best audience. If you
 backup to tape, the occasion will arise when the backup will overflow
 your tape. In this instance, mondoarchive will ask for another tape.
 If you're using cron to start the backup, you won't be able to tell
 mondo that the new tape is mounted and the backup will fail. If you
 backup to CD-R(W), the same situation will arise but sooner.
 </para>
 </sect2>
 <sect2><title>Efficiency</title>
<para>
If your backup already occupies two media, this method will allow
 as much of the backup as possible to proceed during quiet periods.
 Time the backup to start with enough time to complete the first media
 shortly before the operator arrives for work. The next media can
 be mounted and the backup completed asap and minimises the time for
 which users are inconvenienced by the backup (eg. database locked...).

         <title>The Problem</title>
<sect2><title>Cron's environment</title>
<para>
When a user submits a job with cron, their environment is not
 preserved. This is reasonable since cron jobs are typically ongoing
 and may be adversely affected if the user's environment changes subsequent
 to the cron submission. Thus, a cron job should call a script that
 set's up the correct environment before starting the user's desired
 program. The 'at' command does this nicely.
 </para>
 </sect2>
 <sect2><title>Interactivity</title>
<para>
When a job is started with cron, it runs as a background process.
 No interaction with the program is possible (unless it is capable
 of interacting via a FIFO or some such) except termination via its
 pid. The only program that I know of that allows such interaction
 and serves as a wrapper for other processes is 'screen'
 </para>
 </sect2>
 <sect2><title>Screen</title>
<para>
There's one little problem with screen though. It expects to
 attach to a terminal when it first starts. This won't happen under
 cron so screen will fail. Fortunately, screen comes with a "start
 detached" (-d) option.

<para>FYI, no bad archives have been created since May 2000. Having

trusting the backups.</para>
<para>To view the file differences, look at the file
'/tmp/changed.txt'. Normal differences include logs and other
dynamic system files that changed during the time of the backup
process. If only a few files differ - e.g. files in /var, files
ending in '&amp;#732;', logs, temporary files, /etc/mtab,
/etc/adjtimex - then you know the archives are good. Your logs will
change over time, too. Bear in mind that a difference between the
backup and the live copy does not&nbsp;indicate a flaw in Mondo. It
indicates that you or your filesystem changed the files, so the
backup is no longer 100% up to date. However, that is inevitable,
as your filesystem changes from moment to moment (which is why you
back it up regularly).</para>

Interactive Mode. The interactive mode will provide an 'Editing

geometry.</para>
<para>To move up and down between partitions in the 'Editing
mountlist screen', use the Up and Down arrows. To move between the

<para>One of the nice things about Mondo is that it lets you wipe

reason). You can move from non-RAID to RAID,install and utilize
additional drives, move from ext2 to ReiserFS, etc., all without
risking the loss of data.</para>
<para>If the user excluded a particular partition from backup and
specifically excluded it from the mountlist itself using -E then
Mondo will insert a small (32MB) partition at restore-time, in
order to avoid having to re-jig fstab, the partition table,
etc.</para>

you can still create your own /mnt/RESTORING/etc/lilo.conf and run

Mondo. In other words, you do not have to boot your PC from your
media in order to restore files. Mondo was originally designed
for disaster recovery - situations in which you cannot boot your

<qandaentry>
        <question><para>Q: What is "Mindi"?</para></question>
        <answer>
<para>A: Mindi, a.k.a. Mindi-Linux, makes a mini-distribution from
your kernel, modules, modules, tools and libraries. It can also
generate an El Torito 2.88/5.76MB boot disk image. Mondo uses Mindi to
create a mini-distro, then boots from it and runs on it.</para>
</answer>
</qandaentry>
<qandaentry>
        <question><para>Q: Why is it called "Mondo"?</para></question>
        <answer>
<para>A: The Teenage Mutant Ninja Turtles described cool things as
'mondo'. Hugo Rabson wasn't sure what to call this project. 'Faust' was one
idea he had, partly as a dig at his former boss who practically owned
him because of his legal status at the time. In the end, he chose
something short and distinctive.</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: Mondo does not work on my system. It
                keels over and dies. What's wrong?</para></question>
<answer>
        <para>A: It works on Red Hat 7.x/8/9, RHEL 2.1/3/4, Mandrakelinux 8.x/9.x/10.x/200x, Fedora 4/5/6, Debian 3.x, most flavors
                of SuSE/SLES, some flavors of Slackware, etc.
The more distributions we support, the more moving targets we have to
hit. Please bear this in mind when e-mailing the list. :) If you
would like to help us by beta-testing Mondo (or Mindi) on your PC
then we would be very interested in working with you to work around
the eccentricities of your Linux distro. However, rest assured, 90%
of the bugs reported are actually symptoms of FooLinux X.Y's
unique way of doing things.</para>

        <question><para>Q: Can I trust Mondo?</para></question>
        <answer>
<para>A: Mondo has generated reliable archives since May 2000.
Lost data occured by using bad CD-R disks and not verifying their
contents. Some users have not tried booting from their CD until
crunch time. Remember to boot into Compare Mode to verify the
backup before you trust it. If Mondo did not work, you would not be
reading this. If it does not work for you, your kernel is usually
the culprit. Check <link linkend="overview-sysrq-kernelreq">Linux Kernel
support</link> to see what your kernel should support. Please
e-mail the list if you need some help with this.</para>
</answer>
</qandaentry>

        <question><para>Q: How do I report a bug?</para></question>
        <answer>
                <para>A: E-mail the bug report (mondo.err.xxxxx.tgz) to the &ML;. 
                        Ok you've read it already but it's really important if you want help.

<question><para>Q: Mondo says, "XXX is missing," and
                then terminates. What's wrong?</para></question>
<answer>
<para>A: A good Linux distribution should contain XXX but the
designers, in their infinite wisdom, decided not to include that
particular tool. Check <ulink url="http://www.mondorescue.org/downloads.shtml#dependencies">Related
        Linux Packages</ulink> and install the missing package. If that
fails, contact the vendor/distributor/manufacturer/designer of your

<question><para>Q: Can Mondo handle multi-CD backups and
                restores?</para></question>
<answer>
<para>A: Yes, up to twenty CD per set. This 20-CD limit results
from laziness on mondorescue's part. I'll be removed in the future. However, if
your system occupies more than 20 CD, may it's time for another type of media ?

<qandaentry>
<question><para>Q: Can Mondo handle Linux/Windows
                dual-boot systems?</para></question>
<answer>
<para>A: Yes. If your system currently boots into Linux or Windows
via LILO, you can backup and restore both OSes at the same time
using Mondo. If you are using NTFS then add the switch, '-x
&lt;device&gt;'.</para>

<qandaentry>
        <question><para>Q: Does Mondo support LVM?</para></question>
        <answer>
<para>A: Mondo supports LVM v1 and v2. Mondo backs up and restores your
existing setup but it does not make it easy for you to change your
LVM configuration, at the moment. You have to edit <filename>/tmp/i-want-my-lvm</filename> at boot-time
to do that.</para>

<question><para>Q: Can I create a Mondo CD and then use
                it to create an archive of any OS on any PC?</para></question>
<answer>
<para>A: Not yet. You can use Mondo to backup Linux or
Linux/Windows dual boot. One day, Mondo will let you backup
partitions it can't read or write, by treating each partition as
one long file to be backed up. This file will be chopped,
compressed and archived like any other big file.</para>

<question><para>Q: When I try to boot from the Mondo CD,
                it says, "UPGRADE YOUR RAM". What does that mean?</para></question>
<answer>
<para>A: Recompile your kernel and add Virtual memory file system
support. Take a look at <link linkend="overview-sysrq-kernelreq">Linux
Kernel support</link> to see what your kernel must support. (Of
course, if your PC has less than 64MB of RAM, you could always...
what's the phrase? I know, upgrade your RAM!)</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: When I try to boot from the Mondo CD,
it says something about not finding my CD-ROM drive and then it
blames the kernel. What does that mean?</para></question>
<answer>
        <para>A: Your kernel must support initrd, loopfs, IDE|SCSI|USB CD-ROM's, and
ramdisks. Take a look at <link linkend="overview-sysrq-kernelreq">Linux
Kernel support</link> to see what your kernel must support. If
your kernel does not support these things, Mondo will not boot from
your CD. However, when running Mindi, you may choose to use _its_
kernel instead of your own.
</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: The LILO Mondo media takes ages to
                boot. How can I speed it up?</para></question>
<answer>
<para>A: Edit mindi (it's a shell script, btw) and change
LILO_OPTIONS="" to LILO_OPTIONS="-c". This enables map compaction
in lilo and speeds up booting, for more info see the lilo man
page.</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: Why won't Mondo boot from my CD?
It says my kernel is flawed/outdated/ whatever, and when I wrote to
the ML, they told me the same thing... but I still don't get it. I
mean, my kernel works for everything else. Why not Mondo?</para></question>
<answer>
<para>A: Because Mondo makes a boot disk using your kernel. I bet
your other software doesn't do that. Also, not all kernels are
suitable for boot disks. I'm sorry but that's Life. Upgrade your
kernel and/or recompile it. Take a look at
<link linkend="overview-sysrq-kernelreq">Linux Kernel support</link> to see
what your kernel must support.</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: Why do I only need a boot disk if I'm
                using a tape drive? Where are the data disks?</para></question>
<answer>
<para>A: On the tape. :-) The first 32MB of the tape will be set
aside for a large tarball containing the data disks, a list of all
files backed up, and other sundries. If Mondo and Mindi do their
respective jobs then you won't need additional media, just the
boot media and the tape(s).</para>
<para>As of 2.2.6 mondorescue does support OBDR for tapes. 
        So if you have a tape supporting that protocol such as HP tape readers, you may directly boot from the tape as well.</para>
</answer>
</qandaentry>
<qandaentry>
<question><para>Q: Why does it say, "Process accounting
                FAILED" when I reboot?</para></question>
<answer>
<para>A: You were using Process Accounting. Red Hat (or whichever
distro you are using) does not provide a startup/shutdown script
yet. So, when you try to backup the process log, it just grows and
grows as Mondo tries to back it up. Mondo doesn't back it up
anymore and that's why. The unfortunate side-effect is... well,
what you see on your screen. Type 'touch /var/log/pacct' and then
'paccton' to fix the error message.</para>

<question><para id="TAPENICE">Q: My tape drive
doesn't play nicely with Mondo at boot-time. What do I do?</para></question>
<answer><para>A: Play with the 'mt' command (package mt-st). Use its setblksize and
defblksize switches to reconfigure your tape drive if necessary.
Some tape drives just are painful. If yours is one of
them then God help you. Mondo can handle any tape drive whose drive
and firmware can handle fopen(), fwrite(), fread() and fclose().
Mondo uses standard C libraries to talk to your tape streamer. If
your tape streamer can't handle that then you had better call a
priest. Either that or ask for a refund.

<question><para>Q: Does Mondo support my tape

<answer>
<para>A: If your tape drive and its firmware and the kernel-level
driver support fopen(), fread(), fwrite() and fclose() - standard C
library calls - then yes, Mondo should support it. If not, well,
you need a refund. :) Mondo plays nicely with any sane, sensible
drives. That's most of them, by the way. :) If your drive doesn't
play nicely with Mondo then you may try tinkering with setblksize
and defblksize using 'mt', or tweaking Mondo's block size by
recompiling it with make INTTAPE=4096 or INTTAPE=8192 or something.
Other than that, you need a priest or a refund.

<para>A: Mondo should be able to handle almost any hardware. So
long as your kernel and modules support it, Mindi will support it
and therefore so will Mondo.</para>

        <question><para>Q: Why doesn't cdrecord -scanbus work ?</para></question>
        <answer>
                <para>A: If you have a 2.4.x kernel (typical example are fedora legacy kernels for redhat 7.X/8/9) and an IDE CDRW device, and the drive is not
listed when you run

<informaltable><tgroup cols="1"><tbody>

</row>

try adding the following kernel option to your boot script to enable
SCSI emulation: hdx=ide-scsi, where "hdx" should be replaced with the
appropriate drive letter of the CDRW device, e.g., "hdc".

<para>A: Yes. Boot in Interactive Mode and edit the mountlist using
the snazzy new mountlist editor. Mondo can now edit your RAID
partitions for you. Just open /dev/md0 (or whatever) and select
"RAID.." to start. Or, to add a RAID device:</para>

<para>A: Yes. Just backup as usual but add '-d /mnt/nfs' or
wherever your partition is mounted; don't use '-Oc' or '-Ot' at
all; just '-Oi -d /root'. Then, after booting from the media
which Mondo generates, you need to type 'ISO' at the

<question><para>Q: When I compare my archives to my file
system, Mondo tells me there are differences or errors. Are the
archives bad?</para></question>
<answer>
        <para>A: Look at <filename>/tmp/changed.files</filename>; if the files are logfiles,
temp files or files which you think you may have changed recently
then the archives are simply out of date, albeit only by a few
minutes. Not a problem. However, if lots of files in /usr have
changed or if you get lots of errors then perhaps your CD, your
tapes or even your hardware could be to blame. Check your CD writer
or tape streamer.</para>

<question><para>Q: My zip drive is a SCSI drive. When I
restore, Mondo craps out, saying it can't mount the drive (because
there is no disk in it). What do I do?</para></question>
<answer>
<para>A: Restore in Interactive Mode. Delete the SCSI drive from
the mountlist before you restore. Then Mondo won't try to partition
or format it. Next time you backup, use -E /dev/sdd (or whatever
your zip drive is). The /dev entry will be excluded from the
mountlist but not from the filelist. So, when you restore, you
won't accidentally reformat your zip disk. However, after
restoring, you will find that /dev/sdd (the _file_) will still be
present in your /dev directory. Cool, eh?</para>

<question><para>Q: I received a message like, 'Fileset
                NNN failed' during restore. What does it mean.</para></question>

<para>A: It usually means either you had a very large (&gt;2GB)
file which was not archived owing to a flaw in your distro or your
filesystem has changed in relation to the backup.</para>

<question><para>Q: Why does my ext3 partition have less
                space free than when I backed it up?</para></question>

<para>A: Mondo creates a 10MB journal file area. Your journal was
probably smaller than that, hence the difference.</para>

<answer>
<para>A: You said it yourself. You have to do it manually. :) Sorry
but that's about it. At least you have all the tools to do it. I
assume you know how. If you don't, look at i-want-my-lvm (a script
on the ramdisk) if you're using LVM. It should give you a few
clues. RAID is harder but in general Mondo's RAID support is good.
After you've prepped and formatted your drives, run mondorestore
again but say 'no' when asked if you want Mondo to prep or format
your drives.</para>
