lionceau Posted January 14, 2017 Share Posted January 14, 2017 Hello, I've adjusted unRAID to my liking and am at the point where I won't change much in the future. My cache drive is unmirrored because of SATA port restrictions and my preference for XFS. My docker containers, VMs, VM isos, and appdata are only on the cache drive. Is it possible to stop the array and execute dd if=/dev/sdb of=/path/to/external/disk/image.img to save an image of the cache drive to an external drive so I can do the reverse in case the cache drive dies and have a "known good" status without having to reconfigure everything? CA backup already saves appdata to the array every month but that doesn't include VMs and the other stuff. I feel like being able to just restore a raw diskimage using dd on my laptop (with an USB 3.0 dock) would be the fastest and easiest recovery method in case of a failure. Quote Link to comment
RobJ Posted January 19, 2017 Share Posted January 19, 2017 I can't think of any reason why that shouldn't work, but not something I can verify. Quote Link to comment
