As data is only appended, and nothing deleted, commands like ``prune`` or ``delete``
As data is only appended, and nothing removed, commands like ``prune`` or ``delete``
won't free disk space, they merely tag data as deleted in a new transaction.
Be aware that as soon as you write to the repo in non-append-only mode (e.g. prune,
delete or create archives from an admin machine), it will remove the deleted objects
permanently (including the ones that were already marked as deleted, but not removed,
in append-only mode).
Note that you can go back-and-forth between normal and append-only operation by editing
the configuration file, it's not a "one way trip".
