For off-site backups we are running a Bacula SD on another location and the internet connection to it, although quite good for what you can normally get at an office, is not as good as a single ethernet cable. It's slow (100Mb/s) and not very stable.
One of the backups seem to take around 16hs or more to finish. The chances of the connection being lost over that long period of time is quite big. So far in a week I never got a single backup to finish and this is the problem: Bacula seems to start from scratch every time. Can anyone confirm this?
It also seems not to be re-using the volumes, so I already run out of space having 95% of my volumes used by useless pieces of a backup.
Does it mean Bacula cannot work on this conditions or is there something I'm missing about Bacula's configuration? Anything else I should try before giving up Bacula?
