Rsync server settings tab:
----------------------------------------------------
Settings: create, populate and apply.
Activate / deactivate buttons in the frame.
Import user and share management from gadmin-samba.
----------------------------------------------------

One exclude/include for each value in the treeview:
----------------------------------------------------
--exclude="*.tar.gz" --exclude="*.txt" --exclude="/Path"
----------------------------------------------------

Or use this instead:
----------------------------------------------------
--exclude-from=FILE     read exclude patterns from FILE
--include-from=FILE     read include patterns from FILE
----------------------------------------------------

Start backup -> Popup menu:
"Only test, do not transfer any files" [x] (--dry-run)
[ Cancel ] and [ Forward ] button to continue the backup.

Add editors for pre and post scripts.
Use scp upload and ssh to run them for non local backups.
(Pre: Dump database, Post: Cleanup)

During larger rsync calculations/chunk gets theres
no output and it can look like the gui has frozen a while.
Iterating main or updating the process view at an interval fixes it.

Fix: "Cancel backup". Signals all "rsync" processes as is.
