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"
}
}
one of the things I would do is to verify that the excludes do work as
expected. As far as I know, globbing is not supposed to work, for
example. As I'm typically using Options with matching and exclude=yes to
exclude, so I don't have anything to compare against.
While I am quite sure that the JobDef is not the issue

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.
That inspired me to do a quick and dirty shell command (one line):
C=0 S=0 find . -type f -printf '%s\n' | while read f ; do (( S = S + $f
)) ; (( C++ )); if ! (( C % 50 )) ; then echo $C: $S ; fi ; done
In the details of the Fileset:
OneFs: true
Recurse: True
HardLinks: True
Of course my counting above is ignoring all those finer points, but with
the discrepancy you observe, that shouldn't matter much :-)
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?
Definitely. I've never really used btrfs, but the commands
btrfs filesystem du
and
btrfs filesystem df
probably exist for a rason :-)
COW-filesystems, snapshots, sophisticated space and volume management in
file systems make the traditional approaches of checking file system
occupancy a bit too tricky.
Let us know what you find, I'm definitely curious ;-)
Cheers,
Arno
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!
