I use Backupper Professional to make backups from my separtate data-drive.
The drive is 900GB whereoff 408 GB is used for actual data.
When I doe an incremental backup this takes a very long time > 1hr, even when no dat has changed.
I would think that this should only take a few seconds while searching with Windows Explorer for files changed after a certain date only takes 1 second!
It looks like Backupper checks the whole drive for changed databloks and does not use indexes for changed files.
