Backup Central

Hi all,


Lately I have large backups of 10 - 15 Tb that we run weekly because it takes days to complete on an LT04.
Some times the backup stops for some reason near completion.

Is there a way to resume from where it stop?
I mean I can rewrite one tape (the one that got error) if it is that, but rewriting 11 - 15 tapes it is not cool.

Thanks

No. I suggest splitting the job into smaller Jobs if possible.

Bacula does not have this feature. The first error of any kind it sees
cancels the job.

Hi,

Thanks for your answer,
I am pretty new with bacula,

I have to backup weekly over 10 Tb, can you please explain the approach to have one job per tape?

All of my projects are bigger than 1 Tb

Thanks

It's recommended when you have such a large set to physically divide
the fileset into smaller parts if possible. You mentioned projects.
Perhaps you could create 1 job per project + 1 job for whatever is the
rest? Could that work? I actually do this for my medical imaging data
(ConeBeamCT, MR, Ultrasound, LungCT ...) .

This feature is available in Enterprise version of Bacula. It is called Incomplete job and allow to restart a backup job after a failure no matter when a failure occurred.
