NFS just isn't going to perform very well with lots of small files &
directories, or other metadata-intensive operations.
I presume that the NFS server is an appliance of some sort (Netapp,
etc), but if it's just a *nix server, running backuppc on the server
would be much faster.

Hello, i tested BackupPC, and i would like to ask how to make better
performance with NFS.
I have local server and backuppc on it, and I want to save backup on
NFS (mounted to this server). I tweaked NFS mount with
noatime,nodiratime,rsize=65536,wsize=65536 (i have gigabit connection)
but transfer is very low. I tried tar and rsync option and i dont see
any differences, Since nfs dont allow me to set owner and group on it
I disabled this options in config and simillar to this. i turned off
compression. I have a lot of small files and dir. i dont have idea
what can I tweak..
After all tweaks stats are: 16GB in 512min! it says 1.8Mb/s .
