number of backups kept is not configurable

[Jeremy Vies]

It could be nice if we can specify how many backups are kept.

I was thinking along the same lines, but I had hoped that it could be done automatically rather than forcing the user to configure it. For example, the underlying backup tool duplicity has an option to make a new full backup if the previous one is older than X days. We could turn this on at some reasonable time (maybe 3 or 6 months).

I haven't done that yet because all of a sudden one of your backups would be taking a full day. I was waiting until duplicity got the ability to resume from an aborted backup. That way Deja Dup could just start a long backup and it wouldn't block the user's ability to get on with their life, so they wouldn't care how long it took, in theory. Duplicity's maintainer is working on this functionality right now.

Does that sound like a plan?

As a home user, I think 3 months is very long !!
On my side, I was thinking of something more like 1 or 2 weeks, with a daily
save.

Theory is where you know everything, but nothing works; practice is where
everything works, but nobody knows why. Here we combine theory with
practice; nothing works and nobody knows why !

Good point. The choice of when to start a new backup is probably a function of how often you make incremental backups.

So if you make daily incremental backups, you'd want every few weeks, but if you did weekly backups, you'd want every few months.
