You're right - that is impossible. I just phrased it badly.

I meant that I:

1. copy the original data to a second machine; this is "the backup"

2a. copy that data to another partition on the second machine

2b. rsync with hard links to a daily-named subdirectory in that "other"
partition; this is "the archive".

I then have my data, a copy of the data, and a disk-space-efficient daily
archive of that data going back some years.

All are accessible and usable using standard utilities such as find, grep, ls,
cp, rsync etc.
