| 58 | Follow the on-screen instructions. This will compare your backup
|

|

| 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 '&#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>
