Hi,
I think it could be useful for you to look into "Maximum Volume Bytes"
and "Maximum Volumes" Pool directives.
For example, I have a 1.4TB raid array where I want to use at most 1TB
for bacula storage.
I have created a "File" pool like this:
# File Pool definition
Pool {
Name = File
Pool Type = Backup
Recycle = yes
AutoPrune = yes
Volume Retention = 30 days
# 40x25 = 1TB
Maximum Volume Bytes = 25G
Maximum Volumes = 40
}
Every volume in the File pool is named FileVolumeXXX, where XXX is a
number (001, 002, ... 040).
Maybe you could create a similar pool for each disk, ensuring no more
that the disk capacity is used by Bacula.
Just my 2 cents.
HTH
Marcello
