just to give an idea of performance moving the backuppc data directory i ha=
ve=20
recently moved all directories=20

backuppc
backuppc/conf
backuppc/pc
backuppc/pool
backuppc/cpool
backuppc/log
backuppc/trash

all those directories were containing 5 800 000 files for about 120 Go on =
=20
reiserfs lvm2 file system on iscsi disk=20
the destination was to ext3 lvm2 file system on iscsi's disks
(the iscsi layout was soft initiator and the lan between the backup server =
and=20
the NAS is Gb)

i have used "rsync -arH source dest" commande line to do the job and=20
the jobs take about=20

=2D> 23 hours on P4 3.5 Ghz
=2D> same place on disk system after (about 120 Go)
=2D> no problem detected on hardlinks all run perfectly on the new directory
=2D-> about 2.7Go of memory during the jobs  <-- =20
( 1Go of real memory and 4Go of swap on local hard disk)

hope this can help somebody.
