58   Follow the on-screen instructions. This will compare your backup
59   against your original file system.</P>

61   FYI, no bad archives have been created since May 2000. Having said
62   that, I would still encourage you to run Compare before trusting the backups.</P>
63  <P ALIGN=JUSTIFY>
64   To view the file differences, look at the file '/tmp/changed.txt'.
65   Normal differences include logs and other dynamic system files that
66   changed during the time of the backup process. If only a few files
67   differ - e.g. files in /var, files ending in '&amp;#732;', logs,
68   temporary files, /etc/mtab, /etc/adjtimex - then you know the
69   archives are good. Your logs will change over time, too. Bear in mind
70   that a difference between the backup and the live copy does <I>not</I>&nbsp;indicate
71    a flaw in Mondo. It indicates that you or your filesystem changed
72   the files, so the backup is no longer 100% up to date. However, that
73   is inevitable, as your filesystem changes from moment to moment
74   (which is why you back it up regularly).</P>
