Thanks for the tips.

/I used the UUID based on a Pluralsight course I watched on Raspberry Pi. I like it better than a label, since labels can be easily changed (esp. in Windows) whereas a partition UUID would only change if the drive were re-partitioned (highly unlikely). And I'm not terribly concerned about "unsightly-ness" in a config file (a simple comment will tell me what it is). I have the ntfs-3g package loaded and the mount -t ntfs is actually using ntfs-3g behind the scenes.
/"Backup script should check whether the disks are mounted or not? "/
Any suggestions on how I could check whether a drive is mounted? Some kind of combination of lsblk & grep??
Thanks
