Hi,

I've been trying out backuppc for a few months now, on my small home 
network. Backing up 2 windows boxes, a linux desktop, and 3 remote 
servers. All using rsync. It works quite well. The backuppool is 120gb 
at the moment, so not extremely big from what I can tell from the 
mailinglist.

However, 2 questions have been brought up.

The backuppc_trashclean is running a lot, and causes _a lot_ of disk-io, 
the disks sounds like they are beeing grinded to dust. I read some older 
posts, and I did an strace on the backuppc_trashclean. I get a bunch of 
unlink-messages and something called getdents. Its mostly unlink though, 
and they all seem to refer to maildir-file(each mail is a file) from a 
mailserver, so lots of smaller files.

unlink("f1206112790.M463161P32730V0000000000000801I00148118_0.mail01,S=90828:2,S")
 
= 0
unlink("f1218413551.M603690P6667V0000000000000801I001480C8_0.mail01,S=46816:2,S")
 
= 0
unlink("f1206813486.M269304P6702V0000000000000801I0014809A_0.mail01,S=93095:2,S")
 
= 0

Is this normal? How long should I expect it to run? Its a raid0 with 
quite normal sata-disks, nothing fancy.

And also, I'm using ext3, is there any benefit to changeing to xfs or 
whats the optimal filesystem?

Thanks in advance,
   Eric
