I’ve moved our backups from a cron job to linode’s full disk backup service.
Their backup service docs explain that if you’ve created any partitions using fdisk the backups won’t work, but don’t mention that backups will also fail if you’ve set a finnix recovery partition on your server. This message really should be added to the failure status message. “Cannot back up filesystem type X” would be useful.
Remove your finnix iso from your configuration profile and it should work!
