Hello Ryan,

The write speed of RAID 50 is higher than RAID 5 and i think this is not the 
problem on my system. The backuppc server input - reading from disk - takes to 
much time. The backups of new hosts with a lot of data are fast. It is only the 
BackupPC_nightly process.

Yesterday i changed BackupPCNightlyPeriod to 4 and it seems ok.

Ok, i change this now.

Ok, i change this now.

I think it is enabled.
