The daily/weekly/monthly backup scheme is often recommended for backups. As far as I understand rsnapshot, backups are really cheap due to hardlinking.

Is there any advantage of say

retain      daily   7
retain      weekly  4
retain      monthly 12

compared to

retain      daily   365

if every new backup just takes a little disk space?

They're cheap, but they're not free. You can keep a year's worth of dailies if you want, and if you've got the space, but the moment you start to have disk space pressure, the cost/benefit of keeping them all isn't going to be worth it. Once you're more than a week out, the need for such high fidelity backups tends to disappear.
