Link to original bug (#16788)

Description

Documentation is silent about how and where backup files are stored https://docs.xfce.org/apps/xfce4-panel-profiles/start

You might not need this info if you use-case is merely to flick between different set-ups, but is essential for any multi-machines setup and for upgrades.

Suggestion:

The default location for backup files in the user's folder is ~/.local/share/xfce4-panel-profiles/

Files are saved as .tar.bz2
