You have to take gemini's daily backups into consideration as well.
They already take up a lot of backup space [1] and several hours to
finish every day. I can see gemini falling over if we start processing
and storing a lot more sources on it.

# journalctl -o cat --since -5d --grep Duration -u borg-backup
Duration: 4 hours 55 minutes 12.55 seconds
Duration: 4 hours 21 minutes 40.80 seconds
Duration: 4 hours 34 minutes 10.01 seconds
Duration: 4 hours 41 minutes 27.67 seconds
Duration: 5 hours 24 minutes 44.55 seconds

# journalctl -o cat --since -5d --grep Duration -u borg-backup-offsite
Duration: 4 hours 9 minutes 2.50 seconds
Duration: 4 hours 24 minutes 19.42 seconds
Duration: 4 hours 40 minutes 17.96 seconds
Duration: 5 hours 33 minutes 47.30 seconds
Duration: 8 hours 2 minutes 20.43 seconds

td;dr: Best to wait until the daily backup duration drops by a lot,
perhaps after more efficient package archiving is implemented (as part
of repod?). The current hardlink-based archive is very disk I/O heavy
(consists of over 61 million inodes).

[1] borg repo size grew from 4.69 TiB on May 13th to 5.86 TiB
currently; trimming the archive once a year helps a bit but the upward
trend persists
