I've been trying Deja Dup for user file backups. It's very good, but the restore facility is limited in LL. You can restore a whole snapshot of your files, but you can't restore previous versions of individual files or folders (and their contents). It appears to be designed to be used in association with Nautilus file manager, rather than LL's usual Thunar. In Nautilus, you can right-click on a file to get an option to restore the version from any previous Deja Dup backup.
After some research, I've found that the solution is to set up a custom action in Thunar:
1. Select Edit and Configure custom actions ...
2. Click on the + button to create a new custom action.
3. Complete the text boxes:
Name: Restore previous version
Description: Restores earlier file versions via Deja Dup
Command: deja-dup --restore %F
4. Select an icon if you want one.
5. Click on Appearance Conditions tab and check all 6 boxes.
6. Click on OK.
You will need to log out and log in again for the change to take effect.
You will now be able to right-click on a file or folder in Thunar to restore earlier versions. If you don't want to be able to restore whole folders (use with care!), don't check the directories box in the Appearance Conditions tab.
