I have full and incremental backups of a large amount of data going

Is there a current and supported way to remove old signatures from
the cache such that they can be restored in the future if required? I
don't mind how manual this process is.
I realize this has been asked in the past and the previous reluctant
recommendation was to use cleanup --extra-clean, but that option was
removed in 2020.
If so, what is the process for removing the old signatures, and what
is the process for getting them back from remote if required?
hey Hamish,
as `--extra-clean` tended to break backups it was no safe option.
if you don't mind manual intervention i'd suggest changing the
target(-folder) by interval, say every year or so. regular full
backups are recommended anyway to minimize chain corruption, so that
seems like a feasible workaround.
after switching the target you can delete the previous archive-dir, as
it is only needed for incrementals or restore and will be recreated if
needed. using option `-name` might ease to find the correct
archive-dir per target(-folder).
