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?
