Unable to access Flash backup

Featured Replies

I have recently had a crash on my server and just prior to that I was getting a warning saying that my flash device was corrupt.

I fully believe I had set up the automatic flash backups set up however when I go to unraid connect online I'm unable to see any back ups at all.

Also, when I click on my server it says I have a pro license but when I try to view my keys it says I don't have any.

I'm really worried I've now lost all my set up and I won't even be able to transfer my pro license to a new flash drive.

Any help would be greatly appreciated!

If the backup is not showing, most likely it wasn't enabled, or it's been 3 months, since they are deleted automatically after that, if you need help reassigning the devices, see below:

The USB flash device is critical to your Unraid server as it stores the operating system, configuration files, and license. If this device fails or becomes unreliable, prompt replacement is essential

Unfortunately this is what has happened, but I was lolucky enough to be able to restore the flash and now I am very conscious of making sure this is kept up to date
