Is it the full or incremental taking the time?
In my experience, fulls are fast, but incrementals are much slower, 
particularly with many files (and probably fragmented discs).

Concerning Flashbackup - as I understand it, a flashbackup is equivalent 
to a full backup, i.e. the whole disc is backed up. If this is the case, 
how much quicker is it than a full backup? As mentioned above, the 
problem we have is with the speed of incremental backups, not fulls.
