[FEATURE] Run script after backup

[Th3M1k3y]

Is your feature request related to a problem? Please describe.
After making a backup, I would like to call a bash script to send a status message and command rclone to upload the files to an offsite server.

Describe the solution you'd like
Just a simple path to the script which can be triggered after a backup run.

Describe alternatives you've considered
It could also be done by monitoring the output directory, but it just feels more right to just run something when something has happened.

I agree with you on this. I would love to trigger a webhook for my Healthchecks instance to know it ran successfully. Perhaps also the possibility of having a script before and a script after, as many backup solutions, such as Duplicati, do.
