Hello

I don't know how big is your storage, but you have configured something like 100 disks of 4TB (= 4000gb)

You define capacity of your pool configuring (Maximum Volume Bytes x Maximum Volumes)

Is interesting to set smaller volumes because if you have some volume error you will loose less data.

If you consider one hard disk of 1TB with a Full Backup daily of 100GB and you want 30 days retention, you will not reach it, because 30 x 100GB = 3.000gb or 3TB, so you only will reach 10 days retention (10 * 100GB) = 1TB


Best Regards

Hey,
I am pretty new in bacula, but started a solution to backup my server via internet through a vpn tunnel. Everything works well, but I am struggling with my disk space:

I am using a RAID 5 for saving my backups. In my bacula-dir.conf the following pool is definied:

Pool {
  Name = File
  Pool Type = Backup
  Recycle = yes                       # Bacula can automatically recycle Volumes
  AutoPrune = yes                     # Prune expired volumes
  Volume Retention = 30 days         # one year
  Maximum Volume Bytes = 4000G          # Limit Volume size to something reasonable
  Maximum Volumes = 100               # Limit number of Volumes in Pool
}

But after a while the disk running out of space. Why bacula will not delete old files?

Client conf:

Client {
  Name = srv-fd
  Address =
  FDPort =
  Catalog = MyCatalog
  Password = ""         # password for FileDaemon 2
  File Retention = 30 days            # 30 days
  Job Retention = 2 months            # six months
  AutoPrune = yes                     # Prune expired Jobs/Files
}

Thanks for your help!
