I don't have any real experience with ZFS de-dup but I'd expect it to help if 
(and only if) you back up large files with frequent small changes - and you 
turn 
  off backuppc's compression, perhaps enabling it in zfs.  Backuppc's pooling 
will already de-dup files that are completely identical, but if even one byte 
is 
different in a large file you will store a complete new copy each time. 
Block-level de-dup would share space for the identical blocks within the file. 
I think you do need a lot of ram on a 64-bit server to perform well, though. 
The 
zfs incremental send/receive function might also work to copy the pool.


Has anyone tried installing backuppc on a nexentastor server?
