I have a File Server running as a VM (Win 2008 R2) configured with the File Server agent for backups and eventually archiving.
The client is configured to make use of the Optimized Scan method which generally works fine.
I have one issue though with a long running incremental after the weekly synthetic full backup. The following incremental run is performing as usual again.
Sizes are reported application size.
Inc before Syn Full1hr100GB
Incr after Syn Full15hr3.2TB
Not sure why the run after the Synthetic Full would state that 3.2TB of data has changed although with deduplication only a couple of GB are actually written to disk.
Any ideas of what could cause this.
