39   Mondo Rescue and Mindi Linux are used primarily as Linux backup and
40   cloning tools. The fall in prices of CD-RW drives and writable discs
41   will allow current users to keep good backups and future users to
42   leverage the cloning capability.</P>
44   Tape drives are more likely to suit your needs if you run a larger
45   installation (or have lots of MP3's). <B>Warning! OnStream drives do
46   not play well with Mondo.</B> I do not know why. It is, in my
47   opinion, something which OnStream should look into. Mondo uses
48   fopen(), fread(), fwrite() and fclose() to interact with tape drives.
49   That works for most drives but some drives just don't like that.</P>
51   I have tested it thousands of times on my own computer with my own
52   data and with no alternate backup regime. It worked for me. Thousands
53   of users testify to Mondo's stability and its ease of use. However,
54   please test it on your own system before you rely on it. In fact, do
55   not rely on <I>any software </I>until you have tested it to see if it
56   performs as expected.</P>
58   To establish that Mondo will behave well in an emergency, please be
59   prepared. Run a test backup as follows:-</P>
60  <UL>
61   <LI CLASS="mvd-P">
63    Run mondoarchive without any command-line options.<BR>
64    <LI CLASS="mvd-P">Backup a subset of files - e.g. /usr/local - to CD
65    or tape. Say 'yes' when asked if you want to verify them.<BR>
66    <LI CLASS="mvd-P">If you are not backing up to CD, please create boot
67    floppies when prompted.</P>
68   </UL>
70   Next, restore archives to your live filesystem.</P>
71  <UL>
72   <LI CLASS="mvd-P">
74    When mondoarchive terminates, run mondorestore without any
75    command-line options.<BR>
76    <LI CLASS="mvd-P">Insert the CD or the first boot floppy when
77    prompted. Press &lt;Enter&gt;. Wait a moment.<BR>
78    <LI CLASS="mvd-P">Select a subset of files to restore, e.g.
79    /usr/local/man and /usr/local/bin. Hit OK.<BR>
80    <LI CLASS="mvd-P">Restore files to /tmp or /root/RESTORED or
81    something similar.<BR>
82    <LI CLASS="mvd-P">When mondorestore terminates, compare the restored
83    files to the originals using cmp or diff.</P>
84   </UL>
86   Finally, simulate an emergency restore.</P>
87  <UL>
88   <LI CLASS="mvd-P">
90    Boot from CD/floppies.<BR>
91    <LI CLASS="mvd-P">Select 'Interactive Mode' at boot-time. (Type
92    'interactive' and hit &lt;Enter&gt;.)<BR>
93    <LI CLASS="mvd-P">Hit OK when shown the mountlist. Say 'yes' when
94    asked if you accept the mountlist.<BR>
95    <LI CLASS="mvd-P">Select files to restore, e.g. /usr/local/man and
96    /usr/local/bin. Hit OK.<BR>
97    <LI CLASS="mvd-P">Restore files to /tmp or /root/RESTORED or
98    something similar.<BR>
99    <LI CLASS="mvd-P">When mondorestore terminates, please reboot and
100    compare the restored files to the originals.</P>
101   </UL>
103   FYI, the subroutines to repartition and reformat your drives are very
104   stable. If you are a RAID or LVM user, you <I>might</I>&nbsp;encounter
105    some difficulties when wiping and restoring from scratch because of
106   the sheer range of filesystem layouts and the impossibility of
107   testing Mondo on every single one. If you have trouble, just drop to
108   the command-line and partition/format manually. Then, call
109   mondorestore, select Interactive Mode, and say 'no' when asked if you
110   want Mondo to partition or format your drives for you.</P>
112   You see, even if you have trouble, you still have two hands and most
113   of the tools you need - lvchange, pvcreate, fdisk, mkraid, etc. - to
114   do it manually. After you have prepped and formatted your drives
115   manually (if you have to), just run mondorestore again and say 'no'
116   when asked if you want to prep or format your drives. What could be easier?</P>
