{note: had a stroke in 2011, am brain damaged with really bad short term memory loss}

My original backup drive {yes, I backup most of my system, using rsync, every day}. It is an external hard drive, and it is mounted as:
/media/kevin/{a number designation}

I had some error messages, and after examining it it was mounted as:
/media/kevin/{a number designation}1

Yes, it appended the number 1 to the original designation.

I changed the script to my rsync thread, and everything is, yet again, working as usual.

Question: Why did this happen?

OK, it is a relatively little problem and easy to fix, but it bugs the {heck} out of me.

Anyone have any idea?

Thank you for reading my question, and have yourself a great day!

No idea.Use label instead of UUID - less likely to cause confusion unless you use dd to backup the partition.

I have seem similar when a device is auto-mounted then disconnected and immediately reconnected before udev has had time to remove the first definition.

If you use either UUID or LABEL and make the mount with either an explicit udev rule or an fstab entry without relying on the auto-mount feature this type of error will not occur.
My backup drive is mounted by fstab with this line The 'nofail' option makes it so when disconnected it does not prevent a boot. The UUID is the uuid of the partition being mounted.

Yeah... I did that once. In general I only power-on my backup drive once a day when I do backups, probably because I don't completely trust external drives, but I did forget to turn it off a few times before I did a reboot. My bad...
And I guess that is why it behaved that way.

Thank you.

I will call this [SOLVED]

Yet again, thank you all for your valuable help {a stroke is a b{bad-word}h}.
Have a fantastic day!
