Thanks for elaborating. What would then be the best solution to write
backuppc4afs's backup store to tape (taking into account that I have a
HP StorageWorks 1/8 G2 autoloader equipped with two Ultrium 920/960
tape drives for LTO3 tapes)?
By "best" I mean that it should be capable of handling the following
- Daily differential backups
- one weekly full backup performed on weekends
- should be easily manageable (to set a few basic parameters at the
beginning of a script or in a dedicated config file is OK but having
to change some lengthy script somewhere in the middle isn't)
- (if available) some ncurses or web based interface would be a plus
- should automatically detect when to change tapes and should initiate
the tape change, so that no manual intervention is necessary
- should ideally be open source or at least freely usable
I'm thinking about using Bacula in order to write disk based backups
to tape(s). Any comments/other suggestions provided that I'd follow
the backuppc4afs path?
Thanks in advance & kind regards,
