|

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>

|
---|
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 '&#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> 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>
