I tried several file systems.
I ended up with ext3, because:
ZFS is not very common in my Linux distros and for backup purposes I
can't fiddle very long in restore case
XFS haven't had a possibility to shrink (which I use from time to time).
BTRFS or GFS als AFAIK cluster filesystems and overkill h
My customer is storing backuppc data on ext3 filesystem. No known issue
exist for this customer, though I have not perform performance comparison
with other filesystem.

I'm a big fan of zfs, but the compression won't be a factor since backuppc
already compresses the data. My one backuppc box runs FreeBSD with the data on
zfs and compression off.
I like managing storage with the zpool and zfs commands much better than md,
lvm and ext4.

I've been doing some ZFS on linux vs XFS benchmarking and I'm seeing that
ZFS is performing slightly better than XFS on reads and writes but sucks on
deletes. If you're not going to be doing lots of deletes and need the
ability to expand (e.g. thinking of using LVM) then ZFS may be a nice
alternati
My experience troubleshooting I/O performance over iSCSI is that Ext4
journaling has a much higher CPU overhead than XFS does. Papers I've read show
evidence that "modern" XFS journaling scales better (better performance) than
Ext4 as disks grow larger. http://lwn.net/Articles/476263/

My original backuppc server, back in the day, used reiserfs3. The latest
incarnation uses ext4. Both have been reliable, though reiser3 is long in
the tooth...And doesn't play well with multicore machines. :)

Personally, I'd recommend xfs, for a number of reasons including speed and
stability. Your mileage may vary, especially depending on your type of
files and the configuration of the array.

Hi,
I'm using BackupPC 3.2.1-4 (official Debian 7 package).
I'm going to configure an external storage (Coraid) in order to backup several
server (mostly Linux).
What kind of file system do you suggest?
Array is 7 TB large (raid6).
Thank you very much
