Even assuming a chunky 512Kbps upload speed, that'd take over a year to
transfer.

Backup strategies depend on:

What you're trying to back up
How often it needs to be done
How far back in time you need to go
How quickly you need to get at it / how easy it is to restore
If you'll want to restore *everything* or just one file

We have about 4 different backup regimes at Watershed (which variously
overlap a bit) to cover all the bases with regards restoring data.

It also depends on what you mean by "cheap" :)

For a basic home one to guard against fire/theft, I'd recommend:
* Some large external drives, to which you copy your data (or a subset
thereof) once a week
* Somewhere to store the disks offsite, or a small 2-hour fireproof data
safe (not a document safe, has to be for data), e.g.
