NAME

SYNOPSIS

DESCRIPTION

Backups are performed by reading the user supplied configuration files and creating tar/gzip archives of the files defined. REOBack is developed to support nightly backups runs and as such, its first run is always a full backup. That is, archive every file regardless of its modification stamp.

REOBack keeps track of what type of backup to perform by storing backup information in the "datadir" directory defined in the configuration file. Therefore, deleting all files in the "datadir" directory will cause REOBack to perform a full backup on its next run.

REOBack can keep backups for any number of days. The variable "backupdays" in the configuration defines this number. For example: a setting of "7", will cause REOBack to keep seven days of backup. It will then delete old backups after reaching the next "7" days. Here's an example:

Assume we want to keep 7 days worth of backup, that is keep a history of any file for 7 days.

backupdays = 7 (set in the configuration file)

DAY BACKUPTYPE | DAY BACKUPTYPE

-------------------------------------------------------

1 FULL | 8 FULL

2 INC | 9 INC

3 INC | 10 INC

4 INC | 11 INC

5 INC | 12 INC

6 INC | 13 INC

7 INC (Delete 8-14) | 14 INC (Delete (1-7)

Notice that it keeps 14 days (backupdays x 2) worth of backup before it deletes the old backups. That is because we don't want to delete the old backups until the next full backups are finished.

When running a FULL backup, REOBack will archive ALL files and directories defined. INCREMENTAL backups on the other hand only archives files that changes since the last full backup. This means that if you added or modified files in a directory defined for backups, after the last full backup time, they will be picked up in every run until the next full backup time passes.
