Hi people:
I'm a little confused about how bacula deals with Pools and Volumes.
I'm using Automatic labeling with a Pool that uses a unique Volume (as
file disk) that is continuosly increasing its size. I have a unique
volume named Vol-0001 with a size of 900 GB and status Append.
If I pretend to preserve Files for 30 days, Jobs for 60 days.. so When
my big volume will be marked as Full or Used to be able to get
recycled? These are my Pool and Clients configurations:
Bacula's retention times for volumes are based on the date the volume
was last written. So, every time Bacula writes a backup job to a
volume, your 15-day retention clock starts over from zero. As long as
your volume's status is Append, bacula will keep writing to it.
With a physical, magnetic tape volume, you will eventually reach the
end of the tape, Bacula will mark the volume FULL, and move on to the
next volume. With logical (disk file) volumes, there is no natural
limit on the size of the volume other than the size of the underlying
disk partition. Since you probably don't want Bacula to fill up your
entire partition, you need to place an artificial limit on the size of
your volumes.
There are several directives you can include in your Pool definition
which will accomplish this:
Maximum Volume Jobs
Maximum Volume Files
Maximum Volume Bytes
Volume Use Duration
See the manual for full details:
