27This 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.
28The goals are to offer a general view of the functions and their best usages.
29Mondo Rescue is a Disaster Recovery Solution which allows you
30to effortlessly backup and interactively restore Linux, Windows and
31other supported filesystem partitions to/from CD/DVD-+R/RW media, tape,
32NFS, ... and Mindi Linux provides the bootable emergency restore
33media which Mondo uses at boot-time.

116This HOWTO serves to help people get started with using
117mondo/mindi as way to backup/restore their system. This is a work
118constantly evolving. It was started by Hugo Rabson and has
119since been worked upon by a number of people. See the
120'<ulink url="&WWWB;about.shtml#devteam">About</ulink>' web
121page for a list of members of the development team.</para>
122
123<para>There are many ways to contribute to the Linux movement
124without actually writing code. One of the most important is writing
125documentation, allowing each person to share their knowledge with
126thousands of others around the world. This HOWTO is designed to
127help you get familiar with how Mondo/Mindi works.</para>

149I rely on you, the reader, to make this HOWTO useful. THis HOWTO is probably incomplete even if it tries to be accurate to the best of our knowledge.
150If you have any suggestions, corrections, recommandations or congratulations :-) don't hesitate to send them to me
151<email>bruno@mondorescue.org</email>,
152and I will try to incorporate them in a next revision or to the &ML;;
153e-mail the list at
154<ulink url="mailto:mondo-devel@lists.sourceforge.net">mondo-devel@lists.sourceforge.net</ulink>;
155tell us what is wrong and how it should be fixed.

279Choose from the list of supported backup media types. The media you
280will use most often are CD/DVD-+R, CD/DVD-+RW, tape, NFS and hard disk. If
281you want to backup/restore over a network, choose 'NFS'. If you
282want to backup/restore to/from a local partition or if you simply
283want to store the ISO images in a local directory until you have
284time or facilities to burn them to CD's, choose 'hard disk'. If you
285choose 'CD/DVD-+R[W]' or 'tape' then in general your hardware will be
286detected and configured for you.

324If you want to backup the whole computer (excluding /sys and /proc,

352Is your kernel sane? Red Hat, Mandrake, SuSE, Debian and Slackware users
353should in general say 'yes' because these vendors are good at
354producing reliable kernels. If you are using Gentoo or LFS
355then your kernel might be non-standard, in which case say 'no' to
356use Mondo's failsafe kernel (provided separately).

393The backup process will now commence. There are some pre-backup
394tasks to be carried out first but the backup is essentially
395underway. To simplify the backup process, you were asked a series
396of questions. Next time, if you like, you could call mondoarchive
397with various command-line switches to control its behavior, instead
398of answering a series of questions. See the man page for details.

409Mondo will make a catalog of all files to be backed up. This may
410take up to five minutes. The list of files will be divided into
411sets, approximately 4 MB (before compression) of files per set.
412This typically takes one minute.

423Mondo calls Mindi. Mindi generates bootable media image and
424auxiliary data disk images which are based on your existing Linux
425distribution and filesystem. That way, you can be sure Mondo's
426tools will be compatible with your existing filesystems and
427binaries: Mondo's tools are your tools. Mindi takes up to five
428minutes to run.

439Finally, Mondo begins backing up your computer. This process may
440take a few minutes or a few hours, depending on how much data you
441are archiving, how fast your CPU is, how much RAM you have, and so
442on. It will backup your regular files and then your large files
443(files larger than approximately 32MB). If you have opted to verify
444your backups, Mondo will do that too.

598If you find this to be the case for your computer, please use '-L'
599to force Mondo to use LILO instead of Syslinux as the boot loader
600for its media. (NB: This has nothing to do with which boot
601loader your hard drive uses.) Also, it is a good habit to specify
602your tape streamer with '-d &lt;device&gt;'. You don't usually need
603to but it's good to be on the safe side. Some computers call your
604tape streamer /dev/osst0, some call it /dev/ftape, ...
605Also, depending on the tape streamer model, a tape should be inserted
606in the tape drive before starting mondoarchive, otherwise it may not

617<para>Mondo Rescue backs up your file system to CD, tape, NFS
618(archives stored remotely) or ISO's (archives stored locally).
619Mondo uses afio as the backup engine; afio is a well-respected
620replacement for tar. In the event of catastrophic data loss, you
621may restore some or all of your system, even if your hard drives
622are now blank. Mondo Rescue can do a lot of other cool
623things:</para>
624<itemizedlist>
625<listitem>
626<para>You can use Mondo to clone an installation of Linux. Just
627backup the crucial stuff and exclude /home, /var/log, etc.</para>

642</listitem>
643<listitem>
644<para>You can backup Linux/Windows systems, including the boot
645sectors. Mondo will make everything right at restore-time.
646(However, do run "Scandisk" when you first boot into Windows, just
647in case.)</para>

650<para>You can use your Mondo backup CD to verify the integrity of

653</itemizedlist>
654<para>Mondo's principal virtue is that it protects you from the
655problems that can arise when you reinstall completely from scratch.
656If you want to wipe and restore your system every year just as a
657matter of 'good practice', Mondo is not for you. However, if you
658want to get up and running again in a hurry after someone breaks
659into your computer and wipes it (or if you accidentally wipe it
660yourself) then Mondo is definitely for you. It will permit you to
661roll back to a known-good installation in a very short period of
662time, sometimes as little as twenty minutes. Even if you backup
663large amounts of data to tape daily and do not want to add yet
664another backup regime, please consider backing up the core
665filesystem (i.e. everything but the directories containing your
666huge database and your prizewinning novel) every month or so, just
667in case. You will be glad you did.</para>
668<para>What is Mondo not?</para>
669<para>Mondo is not an everyday backup program. It is not designed
670to replace tar, afio, kbackup, etc. Mondo is designed to make it
671possible to recover from scratch if necessary. Tar and afio offer a
672quick, convenient way to backup small sets of files, sometimes to
673removable media.</para>

678<para>
679Mindi Linux creates a set of boot/root media images
680that will let you perform basic system maintenance on your Linux
681distro. The principal virtues of Mindi's boot disks are the fact
682that they contain your kernel, modules, tools and libraries. You
683can ask for additional binaries (or other files) to be included on
684the kit. The libraries will be added for you.
685</para>
686<para>Whichever modules were loaded at backup-time, they are
687reloaded at boot-time. So, in theory, you will boot into almost the
688same environment as you were in when you backed up. If you want to
689add files to your Mindi boot disks, edit '&lt;INSTALLPATH OF
690MINDI&gt;/mindi/deplist.txt' and add the files to that list. The
691added files and dependencies, will be spread across the data disks
692at run-time.
693</para>
694<para>Mindi makes sure that Mondo has all the tools it needs at
695boot-time. Mondo uses fdisk, mkfs, cat, less, more, afio, gzip,
696bzip2, your keyboard configuration, your glibc libraries, your
697other libraries, your kernel, your modules, ... which is a lot of tools!
698Mindi takes care of all that, so that Mondo can get on with the job of backing
699up or restoring your data.
700</para>
701<para>Mindi is also handy for making boot CDs/disks which stand on
702their own. You do not need Mondo. Indeed, if you like, you could
703use another backup/restore program with Mindi. Just add it to
704Mindi's dependency list (type 'locate deplist.txt' to find it).
705Mindi will include your software on its boot CD/disks the next time
706you run mindi.

712<title>Linux Backup</title>
713<para>Mondo Rescue and Mindi Linux are used primarily as Linux
714backup and cloning tools. The fall in prices of CD-RW drives and
715writable discs will allow current users to keep good backups and
716future users to leverage the cloning capability.</para>
717<para>Tape drives are more likely to suit your needs if you run a
718larger installation (or have lots of MP3's). Warning! OnStream
719drives do not play well with Mondo. I do not know why. It is, in my
720opinion, something which OnStream should look into. Mondo uses
721fopen(), fread(), fwrite() and fclose() to interact with tape
722drives. That works for most drives but some drives just don't like
723that.
724Also, depending on the tape streamer model, a tape should be inserted
725in the tape drive before starting mondoarchive, otherwise it may not
726recognize the drive.</para>
727<para>Mondo Rescue has been tested thousands of times on various computers.
728It has worked for them.
729Thousands of users testify to Mondo's stability and its ease of
730use. However, please test it on your own system before you rely on
731it. In fact, do not rely on any software until you have tested it
732to see if it performs as expected.</para>

779<para>FYI, the subroutines to repartition and reformat your drives
780are very stable. If you are a RAID or LVM user, you
781might&nbsp;encounter some difficulties when wiping and restoring
782from scratch because of the sheer range of filesystem layouts and
783the impossibility of testing Mondo on every single one. If you have
784trouble, just drop to the command-line and partition/format
785manually. Then, call mondorestore, select Interactive Mode, and say
786'no' when asked if you want Mondo to partition or format your
787drives for you.</para>
788<para>You see, even if you have trouble, you still have two hands
789and most of the tools you need - lvchange, pvcreate, fdisk, mkraid,
790etc. - to do it manually. After you have prepped and formatted your
791drives manually (if you have to), just run mondorestore again and
792say 'no' when asked if you want to prep or format your drives. What

825<title>Mondo Rescue and Mindi Linux
826History</title>
827<para>Mondo Rescue was created in December 1999 by Hugo Rabson as a utility to
828clone Linux/Windows installations. Norton Ghost would not do the
829job, and his boss wanted to jump on the Linux bandwagon. So, he wrote
830a few scripts and shoehorned them into the latest Linux-Mandrake
831CD. Since that time, Mondo grew into a disaster recovery suite for
832Linux and Windows. Mondo forced him to learn about the kernel, its
833initrd initial ramdisk, modules, library dependencies, disk
834partitioning, and the myriad differences between the Top 10 Linux
835distributions.</para>
836<para>The first formal release was made on February 18th, 2000.
837Mondo is currently one of the top five Linux backup/restore
838programs. Mondo has been compared favorably to ArcServe, Arkeia and
839BRU. Although Mondo lacks the more advanced, enterprise-level
840features of ArcServe and Arkeia, for workstations and small- to
841medium-size servers it is ideal because it is small, fast,
842efficient, stable, comes with source code, and is being actively
843developed and supported.</para>
844<para>
845        Since November 2005, Hugo Rabson has tranfered the maintenance
846        of the Mondo Rescue suite to Andree Leidenfrost and Bruno Cornec,
847        both previous developers and packagers of the tool since nearly
848        the begining.

1542        <title>Introduction</title>
1543
1544<para>
1545Mondoarchive is designed to run interactively. That's not strictly
1546 true, if you run mondoarchive without the '-g' switch, it will just
1547 run. However, there is a problem where media changes are necessary.
1548 The user must change the media and tell mondoarchive that the change
1549 has been done. The problem lies in the fact that cron does not allow
1550 user interaction with a job. If you schedule a mondoarchive job via
1551 cron, you better be sure it needs only one media. In practical terms,
1552 this means using tapes or ISOs (if CD-R(W) is your backup medium).
1553 However, for tape users, there's always the possibility that the
1554 backup will overflow the tape while for CD-R(W) users, there is the
1555 added hassle of burning the ISOs in the morning. If your CD_R(W)
1556 backup routinely occupies more than one media, this is not for you
1557 (use the ISO option and burn the CDs in the morning). This HOWTO
1558 addresses the problem by using screen as a wrapper for mondo.

1564<para>
1565Mondo users who wish to automate the backup and whose backups
1566 routinely occupy close to one media are the best audience. If you
1567 backup to tape, the occasion will arise when the backup will overflow
1568 your tape. In this instance, mondoarchive will ask for another tape.
1569 If you're using cron to start the backup, you won't be able to tell
1570 mondo that the new tape is mounted and the backup will fail. If you
1571 backup to CD-R(W), the same situation will arise but sooner.

1574 <sect2><title>Efficiency</title>
1575<para>
1576If your backup already occupies two media, this method will allow
1577 as much of the backup as possible to proceed during quiet periods.
1578 Time the backup to start with enough time to complete the first media

1580 be mounted and the backup completed asap and minimises the time for

1588<para>
1589When a user submits a job with cron, their environment is not
1590 preserved. This is reasonable since cron jobs are typically ongoing
1591 and may be adversely affected if the user's environment changes subsequent
1592 to the cron submission. Thus, a cron job should call a script that
1593 set's up the correct environment before starting the user's desired
1594 program. The 'at' command does this nicely.

1597 <sect2><title>Interactivity</title>
1598<para>
1599When a job is started with cron, it runs as a background process.
1600 No interaction with the program is possible (unless it is capable
1601 of interacting via a FIFO or some such) except termination via its
1602 pid. The only program that I know of that allows such interaction
1603 and serves as a wrapper for other processes is 'screen'

1605 </sect2>
1606 <sect2><title>Screen</title>
1607<para>
1608There's one little problem with screen though. It expects to
1609 attach to a terminal when it first starts. This won't happen under
1610 cron so screen will fail. Fortunately, screen comes with a "start
1611 detached" (-d) option.

1871/etc/adjtimex - then you know the archives are good. Your logs will
1872change over time, too. Bear in mind that a difference between the
1873backup and the live copy does not&nbsp;indicate a flaw in Mondo. It
1874indicates that you or your filesystem changed the files, so the
1875backup is no longer 100% up to date. However, that is inevitable,
1876as your filesystem changes from moment to moment (which is why you

2048geometry.</para>
2049<para>To move up and down between partitions in the 'Editing
2050mountlist screen', use the Up and Down arrows. To move between the
2051main window and the buttons at the bottom, use the Left and Right
2052cursor keys. TAB shifts focus from one screen item to the other in
2053a haphazard fashion, owing to the complexities of the Newt
2054library.</para>
2055<para>If you want to restore selectively, just press &lt;enter&gt;
2056and follow the on-screen instructions. You will be asked to say
2057yes/no to a range of questions.</para>
2058<para>If you are planning to modify your partition table, you would

2173<para>One of the nice things about Mondo is that it lets you wipe
2174your existing system and restore it in any layout you like (within
2175reason). You can move from non-RAID to RAID,install and utilize
2176additional drives, move from ext2 to ReiserFS, etc., all without
2177risking the loss of data.</para>
2178<para>If the user excluded a particular partition from backup and
2179specifically excluded it from the mountlist itself using -E then
2180Mondo will insert a small (32MB) partition at restore-time, in
2181order to avoid having to re-jig fstab, the partition table,

2504would like to help us by beta-testing Mondo (or Mindi) on your PC
2505then we would be very interested in working with you to work around

2526Lost data occured by using bad CD-R disks and not verifying their

2528crunch time. Remember to boot into Compare Mode to verify the
2529backup before you trust it. If Mondo did not work, you would not be
2530reading this. If it does not work for you, your kernel is usually
2531the culprit. Check <link linkend="overview-sysrq-kernelreq">Linux Kernel

2608existing setup but it does not make it easy for you to change your
2609LVM configuration, at the moment. You have to edit <filename>/tmp/i-want-my-lvm</filename> at boot-time

2679<para>A: Ask Debian's designers why they, unlike every other distro

2681kernel. In the meantime, please use '-k FAILSAFE' in your command
2682line when calling Mondo.</para>
2683<para>A: From Sarge onwards, all stock Debian 2.6 kernels should work fine. If
2684you are still using stock Debian 2.4 kernels, FAILSAFE is the way to go.
2685Of course, if you have compiled your own kernel and experience problems,
2686FAILSAFE is the way to go as well, but this is not really

2718Kernel support</link> to see what your kernel must support. If

2781grows as Mondo tries to back it up. Mondo doesn't back it up
2782anymore and that's why. The unfortunate side-effect is... well,

2805Some tape drives just are painful. If yours is one of
2806them then God help you. Mondo can handle any tape drive whose drive
2807and firmware can handle fopen(), fwrite(), fread() and fclose().
2808Mondo uses standard C libraries to talk to your tape streamer. If
2809your tape streamer can't handle that then you had better call a
2810priest. Either that or ask for a refund.

2912you need a refund. :) Mondo plays nicely with any sane, sensible
2913drives. That's most of them, by the way. :) If your drive doesn't
2914play nicely with Mondo then you may try tinkering with setblksize
2915and defblksize using 'mt', or tweaking Mondo's block size by
2916recompiling it with make INTTAPE=4096 or INTTAPE=8192 or something.
2917Other than that, you need a priest or a refund.
2918Also, depending on the tape streamer model, a tape should be inserted

3063                space?</para></question>
3064<answer>
3065        <para>A: Because it need space to create the archive files with afio, then
3066                again space to create the ISO images that you'll be able to burn.

3074<answer>
3075<para>A: Well, (a) use '-T /tmp' or '-T /home' or something in your
3076        call to Mondo. Oh, and (b) check the <filename>/etc/exports</filename> file on your NFS server
3077        and verify the exported filesystem is writable for the client, and relaunch exportfs -a.

3084<answer>
3085<para>A: Yes. Just backup as usual but add '-d /mnt/nfs' or
3086wherever your partition is mounted; don't use '-Oc' or '-Ot' at
3087all; just '-Oi -d /root'. Then, after booting from the media
3088which Mondo generates, you need to type 'ISO' at the
3089console.</para>

3125<question><para>Q: When I compare my archives to my file
3126system, Mondo tells me there are differences or errors. Are the
3127archives bad?</para></question>
3128<answer>
3129        <para>A: Look at <filename>/tmp/changed.files</filename>; if the files are logfiles,
3130temp files or files which you think you may have changed recently
3131then the archives are simply out of date, albeit only by a few
3132minutes. Not a problem. However, if lots of files in /usr have
3133changed or if you get lots of errors then perhaps your CD, your
3134tapes or even your hardware could be to blame. Check your CD writer
3135or tape streamer.</para>
3136<para>Also, don't forget to review <filename>/var/log/mondoarchive.log</filename> for
3137more information.</para>

3155<question><para>Q: My zip drive is a SCSI drive. When I
3156restore, Mondo craps out, saying it can't mount the drive (because
3157there is no disk in it). What do I do?</para></question>
3158<answer>
3159<para>A: Restore in Interactive Mode. Delete the SCSI drive from
3160the mountlist before you restore. Then Mondo won't try to partition
3161or format it. Next time you backup, use -E /dev/sdd (or whatever
3162your zip drive is). The /dev entry will be excluded from the
3163mountlist but not from the filelist. So, when you restore, you
3164won't accidentally reformat your zip disk. However, after
3165restoring, you will find that /dev/sdd (the _file_) will still be
3166present in your /dev directory. Cool, eh?</para>

3172<answer>
3173<para>A: It usually means either you had a very large (&gt;2GB)
3174file which was not archived owing to a flaw in your distro or your
3175filesystem has changed in relation to the backup.</para>

3190<answer><para>A: It sounds as if you are running out of disk
3191space, probably ram disk space. Type 'df -m' to see which
3192partitions are running low on space. Please send as much
3193information as you can to the &ML;. This problem is

3201<answer>
3202<para>A: You said it yourself. You have to do it manually. :) Sorry
3203but that's about it. At least you have all the tools to do it. I
3204assume you know how. If you don't, look at i-want-my-lvm (a script
3205on the ramdisk) if you're using LVM. It should give you a few
3206clues. RAID is harder but in general Mondo's RAID support is good.
3207After you've prepped and formatted your drives, run mondorestore
3208again but say 'no' when asked if you want Mondo to prep or format
3209your drives.</para>
