But MFT checks are mostly quite fast right? To me, the weird thing is the job logs show a data read amount of 3TB (half the volume) and less than 200GB is actually transferred. If some kind of daily process would touch 3TB of files (which causes them to be read if i understand correctly?), how can the actual VIB be so small after in that case? Is VAW scanning all changed files (as marked changed in the MFT by who-knows-what) and looks for blocklevel changes maybe? (i'm not fully aware of the scheduled tasks that take place on the fileserver and what they do, i did not setup this fileserver myself, so i cannot rule out such a process "interferes" with the backup just yet)
It's a virtual machine on a Hyper-V host, having a in-guest iSCSI connection to the data volumes running on the SAN. 1Gbit iSCSI. 16GB RAM VM, running 2vCPU's
yes i'm using the latest VAW build currently available.
