Re: [BackupPC-users] BackupPC data pool

The latency that remote storage adds, particularly at a higher level like NFS or SMB, can really hurt BackupPC's performance. Besides, it is going to hammer the daylights out of that remote storage, leaving very little performance for anybody else.

And while a Drobo is one of the very nicest ones, it is still very much a small NAS box.
BackupPC really wants to be set up on a standalone PC with directly attached disks.

Thanks for your reply. Yeah, we're using a NAS device, but not necessary "those small ones" - using this Drobo B800fs. So NFS would be a protocol-based option for the data pool? Still, iSCSI would be best if not DAS?

I think CIFS (as unix extensions to SMB) technically handles hardlinks
when the source system is unix/linux and the underlying filesystem
supports them. However I wouldn't expect this capability to be very
well tested, because in that scenario everyone would use NFS anyway.
And in the backuppc case it would be much more sensible to just run
the program on the box with the drives. If you are thinking of one of
those small NAS devices that don't support NFS, I wouldn't count on
it.
