Out of free space on backup destination

[sirnacnud]

I was backing up my home directory to an external hard drive and during the backup, the below error screen appeared. The whole UI was locked up and when I checked in htop, mintbackup was using 100% of one core.

I thought that the program was completely locked up, but some time later the error messages appeared that there was no free space left on the destination. mintbackup them seemingly crashed or exited, as the program was not running anymore after briefly seeing the error messages. I'm not for sure if I accidentally clicked "Force quit" in the dialog about it being non-responsive.

I am guessing that mintbackup continued to try and backup each file after there was no free space left on the destination and each file failed with the same error message of no free space.

This was quite a bad user experience. At a minimum, the backup should stop immediately after the first file fails with no free space. It would be a better user experience if mintbackup could check before starting the backup if there is enough free space on the destination.
