Keep 7 copies of a daily backup

for some reason I just don’t get the language of the prune dialogue. I can’t wrap my head around it:

I run a daily backup and want to keep 7 copies. Would this be the correct setting?

Set it like this:


It will be transformed to the following command line options: -keep 0:7 -keep 0:7 -keep 0:7 -a. Edit the prune job, and remove the redundant keep options.

ok, thanks will do.

but isn’t there a better way to formulate this? what, in this case, is “every zero day” supposed to mean?

Zero is a special case here. It means don’t keep any copies beyond Y days old.

Otherwise, you can read it like this: If older than Y days, keep 1 copy every X days.
