Yep. It does that. BackupPC is very disk-intensive.

How long it takes all depends on how fast your machine and disks are.

If it's not broken, don't fix it.
I typically use XFS for backuppc data these days (and ext3 for the
rest of the OS); but mostly because one doesn't run into limitations on the
number of extents when using XFS. Reiserfs is good as well; but might be
slightly more prone to corruption and not recover from corruption as well as
XFS or ext3 (this being largely based on anecdotal experiences, rather than
any sort of real statistical analysys).
