Why on earth you'd backup swap?
Also encrypted swap is pretty easy to setup, then again most distros don't give that option on install.
We have tiny swap, like 1GB, working basically as "early warning" of "hey, this server probably could use few GBs more of RAM". There is very little use for any more swap than that
>I don't think non-cloudy admins realize there are cloudy admins out there with forests of little systems with like 8 GB of ram and 16 GB of storage, so the "old" rules from the 1980s about provision twice your ram as swap would increase the disk required from 16 GB to 32 GB doubling my costs for, essentially, nothing.
The "old rules" for swap were never relevant. But dumb myths die hard.
