[Gluster-users] Backup of 48126852 files / 9.1 TB data

we have a 2 brick setup running on a raid6 with 19T storage.
We are currently facing the problem that the backup (9.1 TB data in
48126852 files) is taking more than a week when being backed up by
means of rsync (actually, ccollect).
During backup the rsync process is continously in D state (expected),
but cpu load is far from 100% and disk is also only about 15-30% busy.
(this is snapshot from right now)
I have two questions, the second one more important:
a) Is there a good way to identify the bottleneck?
b) Is it "safe" to backup data directly from the underlying
filesystem instead of going via the glusterfs mount?
The reason why I ask about (b) is that we used to backup from those
servers *before* we switched to glusterfs within about a day and thus
I suspect backing up from the xfs filesystem again should do the job.
Thanks for any hints,
