Hi All,

 

I'm looking to replace an old WHS2011 system with a new unrRAID one. The new system will need to continue doing a bunch of the things the old one did, so I'm considering using a WHS2011 VM to continue to run a few backup utilities like Resilio (BT Sync), Drop Box, Google Drive, and Google Photos. These are all part of various backup solutions for various media types I use. Once setup in the VM they don't support Network drives as targets, so I would be looking at creating a large virtual hard-drive of around 200GBs to be the target of these various backups. This would put the files in a vHD, in unRAID KVM, on an XFS file system (I think). How resilient is this to corruption/data-loss compared to my original setups of a bare-metal WHS2011 with NTFS drives? It feels like there are more layers between the disks and the files where things could go wrong.

 

Thanks for any help,

Dom

I'm using a Win Server 2012R2 VM for about 6 months with a 2nd vdisk created on a XFS unassigned device for all my Windows PCs backups, no issues so far.

Was there any main reason you went for unassigned? My understanding is that it exposes you to risk due to no parity 'backup', so I assume it was for performance or that you considered the data less valuable?

Since the vdisk is used for backups only, and it's highly unlikely to have 2 disks in 2 different computers fail at same time, I prefer having it as unassigned, for performance and to keep the array spun down as much as possible.
