Just had a thought ... dangerous I know :)

Would it improve backuppc performance to use RAID1 with 3 drives?
Obviously writes are not improved, but it would seem the majority of
work done on the FS are random reads...

ie, new files, and unlinks for old expiring files/backups are the only
writes (ok, plus logging). Other than that, there is a lot of reading
both for every backup as well as for the nightly prune process.

Currently, I'm using linux software RAID1 from md, with 2 x 1TB SATAII
HDD's, but thinking that adding a third HDD might improve performance
(albeit not increasing capacity).

Thanks,
Adam
