Hello,
i played a bit with VMware + NetApp VSC Backup/Restore and was very
surprised by the bad performance of SnapRestore on a NFS Storage.
It took SnapRestore 24 hours to restore a 1TB vmdk! Looking at the filer
usage (sysstat) it looked like the filer just copied
the files out of the Snapshot into the live filesystem with terrible slow
12MB/s. I always thought that SnapRestore restores in a few seconds
because
if just copies the pointers and not the data itself.
I tried the same again (copying out of the Snapshot), this time with
ndmpcopy and got ~350GB/h, which is around 100MB/s and an expected result
Currently we don't own the SnapManager License for VSC - maybe thats the
problem? A short test using the cmdline wasn't faster...
Best Regards,
Markus Schlegel
