Pronounced as "Ray-o-back", REOBack is a simple backup solution designed
for Linux Users AND System Administrators. It is designed to be simple to
set-up and and easy to use. Great as a quick solution for those who
procrastinate about backups.
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. Heres an
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 dont 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.
