Hello,

i've got  a little problem with my bacula server and Full backup :

i have a remote client on a 10 Mbits line (optical fiber) with a lot to backup (more than 30 Gb) and a time frame to do this backup relatively short comparatively (10 hours)

My main problem is that I can't terminated correctly a full backup.
I know that i've got to change either the line or the date size to backup but my question is how a full backup is working in this case ?

Does the next time that the full backup will try to run (and fail), will it be doing it from the starting point or will it restart from the last time it failed ?

In other words, will it do a complete full backup at every try or sort of an "incremental" of the failed full until the full backup is done correctly ?

Thanks.

  
No, it will try to do a complete full backup every time.  This is clearly explained in the FAQ :

"Before doing an Incremental or a Differential backup, Bacula checks to see if there was a prior Full backup of the same Job that terminated successfully. If so, it uses the date that full backup started as the time for comparing if files have changed. If Bacula does not find a successful full backup, it proceeds to do one."

One possible workaround would be to break your single backup job into several smaller jobs, each of which can be completed within your 10-hour window.
