Gluster users - Aug 2013 - Advise needed on backup solution with Gluster astarget

Everything you need to know about hard links is in the documentation:
http://gluster.org/community/documentation/index.php/Arch/Glusterfs_Hard_Links

But I think the solution mostly depends on your workload.. What will be backed
up? Small or large files? Rotations for the backups? What access do the backup
clients have to the backup target? What is the tech on the client? SAN? Local
disks?

Thanks,

It is to backup a distributed volume to another distributed volume on
different HW (duh!). The files are mostly hi-res tif images. I would use
georep but I need retention. I will need hourly, daily, weekly type of
rotations. Both volumes are distributed across 7 nodes each. All is
interconnected with dual 10Gbps network. Size is tens of TB. Daily change
set is wildy varying. Batch of about 3 TB (a USB disk) get added or removed
daily. The files themselves are almost never changes. Sometimes but then
only the EXIF data. Some data sometimes gets moved around on the source
volume.
