We use bacula to backup about 40-60 servers.
For settings config files, a bash script is used. It takes info of txt-files (containing namens, passwords, etc).
This script (about 100 lines) needs to be modified, so it also makes different pools for:
1 Full backup per week
6 Incremental backups for last week
Pruning Incrementals after 7 days
Pruning Full backups after 20 day
I can deliver existing script. Knowledge of bacula for backup may be needed.
