backupcleaner

clean-backups.py

Tool to cleanup backup directory with daily, weekly and monthly backups. This tool removes everything in the specified directory (not recursively by default) except files, containing timestamps in the filename that can identified by this tool as fresh backups.

By default, this tool keeps last 7 daily backups, 4 weekly backups (4 last monday backups) and 3 monthly backups (1st day of last 3 months). You can redefine this by command line parameters.

This tool expects timestamps like this: 20220531 (May 31, 2022), but of course, you can redefine this.
