We don't do many FLR restores, but recently did a larger one, large being about 100GB with lots of files. Using FLR and copying to a new destination, we were seeing about 100KBps. This was slow to the point of failing the task. Estimated run time was 20 days. I wound up do a full restore and booting the temp server and just copying files. That's more work that it needs to be for this task.
I realize restoring from a Data Domain is going to be "slow".
Support had me run a DISKSPD test and random 4K reads generated about 1.3MBps
I just let FLR run for an hour on a test restore and only managed 26 files/51.6MB before canceling it. That works out to 14.4KBps, which is only 1% of the expected 1.3MBps speed
Support seems willing to put this on the Data Domain (as usual)
It's a simple environment, 1 Veeam server, VMware vCenter, the Data Domain and enterprise class underlying equipment
So my question is, what should I expect here speedwise?
