How to make snapshots on custom schedule (manual crontab entry) #881

Open ntropia2 opened 6 years ago

ntropia2 commented 6 years ago

I think my issue is similar to another issue [1]. It would be great if BiT would be able to extend the support for the crontab format, and allow backups to run only on business days, e.g. "0 0 1-5".

I would imagine this is a rather common scenario, when people don't alter files over the weekend, so it is possible to save the backup disks some wearing.

I can always edit the crontab manually, but it gets constantly overwritten by BiT.

Thanks a lot for the great work!

Just deactivate the schedule and add you crontab line manually without removing the other lines in crontab. This should keep your custom lines.

This has been answered above (and here: https://github.com/bit-team/backintime/issues/880#issuecomment-380594251), but I think it's something that should be documented, or maybe even shown in the GUI.

I can imagine that users might wonder: "If backintime simply uses good old contab for scheduling, how can I define my own custom schedule by writing my own crontab line?"

I could even imagine a "custom contrab schedule" feature, where you could enter your own scheduling code (like 0 0 * * Mo-Fr) in the GUI, but it would probably be tricky to verify and sanitize the user input.
