Prune daily duplicates

[marsianer]

Did I understand correctly that this allows me to prune multiple backups within a day?
As a result, I have one backup per day regardless of how often the backup was run?

borg prune --keep-daily=-1

Yes and No.

From the docs:

--keep-daily 7 means to keep the latest backup on each day,
up to 7 most recent days with backups (days without backups do not count).

https://borgbackup.readthedocs.io/en/stable/usage/prune.html#description

So, yes, it'll keep one backup (the last one) on these days.

But the number given refers to the amount of days (not to the amount of kept backups per one day).
