The backup of same size to a USB 3.0, take 18 hours!! And througtput resides on 'C:' (vmware) and 'X:' (USB 3.0). On second server, have configured a softraid in windows 2008 r2 (equal to first server). But the size don't increase, only time is more than if i backup only the frist plex. But, on raid, the first disk is backuped in one hour. The backup of 450Gb to a USB 3.0 drive is fast. On first server, have configured on windows 2008 r2 sp1 a softraid.

On first server, have configured a raid 4 HDs. 4x 1TB HD 7.2k Sata 2 64Mb, 16Gb DDR ECC and 1x 2Tb USB 3.0 You can also configure replication for other VM.įor the backup - use a SATA disk as primary backup repository, and USB disk only as target for secondary backup copy.īest is to have a separated dedicated backup server (a regular PC with large SATA disk and USB3 controller will be great),īut if you use a VM, make sure to use SATA and not USB as primary repository for daily backups. Remove all disks from HD4 (keep the VM only on single disk HD2).Ĭonfigure replication from HD2 to HD4, running once per hour for example. * Instead of software raid - you can use replication.

This will thrash both physical SATA disks and response times will be bad for several long hours, just because of unclean shutdown. You will also have problems after power failure - Windows will try to resync all mirrors at the same time. The snapshots problem you currently have - which will probably get worse if not fixed! * Get rid of the software raid, as it can cause some troubles such as: * Fix the stale snapshots by shutting down the VM and trying to consolidate disks.
