Question about Auto CleanUp and BackUp

Hello,

I’ve been using UrBackUp for only a few days I’ve read the documentation and a few posts but I haven’t found an answer.

I would like to have a Full Backup once a day at night (01:00 - 06:00)
under Settings > File Backups ‘Interval for full file backups’ = 1
under Settings > Client ‘Backup Window’ set for 1-7/1-6

I would like to keep those backups for a week
so if I have 1 backup a day my “minimal number of full file backups” should be 7
max can be 10.

I did not configure an archive due to the mini and max number of files I can keep.
I also tested the manual cleanup.bat it did not remove backups below the minimum amount.

My question is what triggers the automated cleanups?
I’ve set cleanup window time to UTC and the timezone where the server is installed and it does not trigger into action
server logs also do not show why the cleanup isn’t running.

What am I doing wrong here?
cleanup window - 1-7/5-8

Thanks for your feedback
