We're using Bacula (Bareos is a fork of it) for backups.
Never had any problems doing backups of Gluster volumes.

Hello,
I have cross-posted this question in the bareos-users mailing list.
Wondering if anyone has tried this because I am unable to backup
data
that is mounted via Gluster Fuse or Gluster NFS. Basically, I have
the
Gluster volume mounted on the Bareos Director which also has the
tape
changer attached.
Here is some information about versions:
Bareos version 14.2.2
Gluster version 3.7.2
Scientific Linux version 6.6
Our Gluster volume consists of two nodes in distribute only. Here
is the
configuration of our volume:
[root@hgluster02 ~]# gluster volume info
Volume Name: export_volume
Type: Distribute
Volume ID: c74cc970-31e2-4924-a244-4c70d958dadb
Status: Started
Number of Bricks: 2
Transport-type: tcp
Bricks:
Brick1: hgluster01:/gluster_data
Brick2: hgluster02:/gluster_data

performance.io-thread-count: 24

server.allow-insecure: on
server.root-squash: on
performance.read-ahead: on
features.quota-deem-statfs: on
diagnostics.brick-log-level: WARNING
When I try to backup a directory from Gluster Fuse or Gluster NFS
mount
and I monitor the network communication I only see data being
pulled
from the hgluster01 brick. When the job finishes Bareos thinks that
it
completed without error but included in the messages for the job
are
lots and lots of permission denied errors like this:
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot open
"/export/rclough/psdv-2014-archives-2/scan_111.tar.bak":
ERR=Permission
denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot open
"/export/rclough/psdv-2014-archives-2/run_219.tar.bak":
ERR=Permission
denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot open
"/export/rclough/psdv-2014-archives-2/scan_112.tar.bak":
ERR=Permission
denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot open
"/export/rclough/psdv-2014-archives-2/run_220.tar.bak":
ERR=Permission
denied.
15-Jul 02:03 ripper.red.dsic.com-fd JobId 613: Cannot open
"/export/rclough/psdv-2014-archives-2/scan_114.tar.bak":
ERR=Permission
denied.
At first I thought this might be a root-squash problem but, if I
try to
read/copy a file using the root user from the Bareos server that is
trying to do the backup, I can read files just fine.
When the job finishes is reports that it finished "OK -- with
warnings"
but, again the log for the job is filled with "ERR=Permission
denied"
messages. In my opinion, this job did not finish OK and should be
Failed. Some of the files from the HGluster02 brick are backed up
but
all of the ones with permission errors do not. When I restore the
job,
all of the files with permission errors are empty.
Has anyone successfully used Bareos to backup data from Gluster
mounts?
This is an important use case for us because this is the largest
single
volume that we have to prepare large amounts of data to be
archived.
Thank you for your time,
