|

| 56 | <para>FYI, no bad archives have been created since May 2000. Having
|
|---|
| 57 | said that, I would still encourage you to run Compare before
|
|---|
| 58 | trusting the backups.</para>
|
|---|
| 59 | <para>To view the file differences, look at the file
|
|---|
| 60 | '/tmp/changed.txt'. Normal differences include logs and other
|
|---|
| 61 | dynamic system files that changed during the time of the backup
|
|---|
| 62 | process. If only a few files differ - e.g. files in /var, files
|
|---|
| 63 | ending in '&#732;', logs, temporary files, /etc/mtab,
|
|---|
| 64 | /etc/adjtimex - then you know the archives are good. Your logs will
|
|---|
| 65 | change over time, too. Bear in mind that a difference between the
|
|---|
| 66 | backup and the live copy does not indicate a flaw in Mondo. It
|
|---|
| 67 | indicates that you or your filesystem changed the files, so the
|
|---|
| 68 | backup is no longer 100% up to date. However, that is inevitable,
|
|---|
| 69 | as your filesystem changes from moment to moment (which is why you
|
|---|
| 70 | back it up regularly).</para>
