I want to backup my complete Unraid server to an unassigned external HDD with rsync.

I only have one Disk in the array, one cache drive and no parity.

For that I have the CA Appdata Backup/Restore v2, Unassigned Devices and User Scripts plugin installed.

With the CA Appdata Backup/Restore v2 plugin, I backup the Unraid USB stick, the appdata and the libvirt image.

 

So now the only thing which isn't backupped, is the media on the array and cache drive, right?

My rsync command in the User Script plugin is

rsync -av --delete --exclude '/mnt/disks/*' /mnt /mnt/disks/Backup/backup

Is that too much?

Do I only need to backup /mnt/cache and /mnt/disk1 or maybe only /mnt/user?

I want the easiest way to restore my whole unraid server if it fails.

 

Thanks for your help and sorry for my bad english.

It is too much because /mnt/user will duplicate /mnt/cache and /mnt/disk1.

 

For fastest restoring from backup, rsync /mnt/cache + /mnt/disk# (where # is a number), with each location has its own directory in the backup drive.

 

I know rsync has way to exclude stuff etc. but it's better in your case to have 2 separate lines in the script, 1 for /mnt/cache and 1 for /mnt/disk1.

That way if there's interruption / crash / error etc., you know for sure what needs to be rerun.
