I'd go for (B), especially if you're continuing to do daily backups, so
the oldest backup with an alternating pattern is 2 days.
I do daily backups to a permanently-connected drive (I used to use
rsnapshot for that, then rdiff-backup, now I use borg); monthly syncs of
that drive to one of two external drives (rsync of the borg repository),
which live off-site and I alternate those. If I lose my
permanently-connected backup drive, one of the external drives is a
month old and the other two months old, which I am happy with.
