Deleted Max Age
When set to a number greater than zero, AutoExpire will force expiration
of Deleted recordings when they are this many days old.
Its default is 0. It existed in 0.21 (it was added during the 0.20-0.21
development cycle just a couple of months after the "Auto Expire Instead
of Delete Recording" option).
The default /must/ be 0, though, because we don't want to delete
/anything/ at all unless a) the user tells us to or b) we have to delete
something to make room for new recordings.
In truth, though, the setting isn't very useful as permanently deleting
the recordings in the deleted recording group has no benefit at
all--it's equivalent to telling the Linux kernel to not use RAM to cache
disk contents. It made sense at the time that the setting was added
because users with full disks had no idea how much space was consumed by
Deleted recordings, but that information (and information about how much
space is used by LiveTV and auto-expirable recordings) is now reported
in the backend status page (and will be reported in the frontend's
System Status page "soon").
So, by telling your system to permanently delete any Deleted recordings
after 1 day, you're saying, "There's no possibility whatsoever that I
may reconsider whether I should have deleted that recording after the
first 24 hours."
Unused storage is wasted storage.
