I have a server I've recently setup and it has a 4 TB disk. I restore a 200 GB SQL database to it every week. When I run the restore using Backup Exec 2014 it stops at 0 bytes, but I can see in the resource monitor of the server I'm restoring to that it's writing bytes to the disk. Eventually after around 30 minutes the Backup Exec will show the data actually transferring to it (byte count). I tried restoring an even bigger database to it and it took even longer before it started.
I have another server that's lower spec that this one on the network, it has slower disk, but the backup operation starts transmitting bytes straight away.
It seems as if the Backup Exec on the new server is attempting to do some pre-restore checks like checking for free space, but I'm not sure. I can't figure out why it does this for one server and not the other? They are pretty much identical.
