I am having issues with performance on my VMware backups using SAN mode. I notices in BOL the following statement. SAN transport generally provides the best performance for thick disk restores, but the worst performance for restoring thin disks. For thin disk restores, NBD or NBDSSL is usually faster.
A side note our library is on a nas so we are using SN mode all the way through the backup process. Since all my VMs are thin provisioned would be better running NBD?
Next question Can I backup in SAN mode and restore using NBD? I noticed in the restore you can select what mode you want to restore.
We are running V11 SP15
