The subject is a bit short, let me explain:

Bacula has a job defined like this:

Job {
  Name = "ivy-job-projects"
  Type = "Backup"
  Level = "Incremental"
  Messages = "Standard"
  Storage = "File"
  Pool = "File"
  Client = "ivy"
  Fileset = "ivy-projects"
  Schedule = "WeeklyCycle"
  JobDefs = "DefaultJob"
  SpoolData = no
}

With this Fileset:

Fileset {
  Name = "ivy-projects"
  Include {
    File = "/home/sgw/projects"
    Options {
      Signature = "Sha1"
    }
  }
  Exclude {
File = "/home/sgw/projects/packer/my-work/packer_sgw_builds/packer_output" File = "/home/sgw/projects/docker/qemu-docker-1/qemu_storage/debian/*.iso"
    File = "/home/sgw/projects/packer/builds/cache"
  }
}

While I am quite sure that the JobDef is not the issue (another Job based on that works fine), here the:

JobDefs {
  Name = "DefaultJob"
  Type = "Backup"
  Level = "Incremental"
  Messages = "Standard"
  Storage = "File"
  Pool = "File"
  Client = "tx100-fd"
  Fileset = "Full Set"
  Schedule = "WeeklyCycle"
  WriteBootstrap = "/opt/bacula/working/%c.bsr"
  SpoolAttributes = yes
  SpoolData = no
  Runscript {
    RunsWhen = "After"
    RunsOnClient = no
    Console = ".bvfs_update jobid=%i"
  }
  Priority = 10
}


Now, what's the problem?

As you can see above, I try to backup the directory "ivy:/home/sgw/projects" minus some excluded files etc

# du -sh /home/sgw/projects
29G     /home/sgw/projects

But the resulting backup on bacula is ~ 164 GB in size!

Why that?

I browsed the directory for links etc ... nothing special.

In the details of the Fileset:

OneFs: true
Recurse: True
HardLinks: True

If I disable Hardlinks, the Estimate looks the same as before.

I browsed the Files in the Job to spot errors, with ~400.000 files that's a bit tough.

That directory is located in a btrfs-pool, might that play a role here?

For comparison I created a second task for the parallel folder "projects_legacy". This one works great, same settings etc -> correct size on the volume(s).

Any hints here? Thanks a lot, this would save me time and space on storage!
