Florian (Nice)I use restic for backups. Great but it is cumbersome to build up some regular update strategy around that. However there is a create tool resticprofile. https://creativeprojects.github.io/resticprofile/index.html, to close that gap. One can schedule backups for example via Systemd Timers. This tool is even mentioned in the official docs of restic itself, https://restic.readthedocs.io/en/stable/040_backup.html#scheduling-backups.
One caveat it has no packages in the official Linux distributions.
However it has build binaries on github.
