For backups, I prefer snapshot backups such as rsnapshot or Back in time,
both use rsync underneath so duplicates are simply hard links

I am a big fan of rsync. I particularly like the "--link-dest" feature:

I'm coming into this rather late since I'd somehow been unsubscribed

What does the command "blkid /dev/sdX" say? If the device is
partitioned then it should return the partition type (PTTYPE):
/dev/sda: PTUUID="2d5ed796-ad53-4317-a7bc-2e0ad85d90d1" PTTYPE="gpt"
One thing you can do is to set up a new partition table. Doing that does
not erase.
Formatting does overwrite data. But, I would practice with a thumb driver.

Not sure why we're still beating this dead horse, but that's just not the
case. When I formatted the drive, I formatted sdx1.
It's not a matter of opinion, nor is it a subject for voting to decide what
happened.

I just checked with "journalctl -xe" after another unsuccessful attempt to
mount the drive, and found a duplicate UUID error.
A quick google search of the error message yielded the solution: I ran
"sudo xfs_admin -U generate /dev/sdf"
and was then able to mount /dev/sdf successfully.

I have an 18TB external hard drive that recently suffered a loss. When I
first set it up, I formatted it as a single partition with an xfs
filesystem.
Yesterday I was trying to figure out how to export it via nfs, and during
one of my attempts I used "mount --bind" to mount it under /export.
