SafePoint = SlowPoint

SafePoint is incredibly slow when backing up to an attached USB disk.

After 9 hours of copying it is only 23% completed of 1.5TB. It has another 2 days before completion.

To keep things in perspective. IT took 8 hours to copy 1.5TB of data over a 1GB network from one network share to the MyBook Live Duo in Raid 1. And SafePoint estimates 2 days for backup?

Safepoints use RSYNC.

RSYNC generates hash tables with checksums for every file it backs up so that it can quickly detect changes to files after their initial backup.

Future backups will be MUCH faster since only changes are backed up.
