You just use cold backups.
For home, I have two USB disks I use for backups and I alternate which I use. Neither is plugged in at the same time. At least one is always "cold".
For larger scale, you can do the same thing with tape. One tape backup goes off-site (perhaps) or at least cold.
The cost isn't that high. A USB spinning disk may cost a third to a 5th that of your SSD hard drive. And you can get hard drives up to 18TB now. But even a portable 2TB USB-powered 2.5in external hard drive is only $60, so this is a cheap and robust strategy.
- benhurmarcel 5y agoThat mitigates the risk, but it relies on the assumption that you'll notice when files get encrypted. It's not a guarantee, malwares can hide themselves long enough for you to plug both disks before you notice.
- Robotbeat 5y agoTrue, but I don’t rotate them every day. Maybe once a week or month. Unlikely to not notice by that time. With tape backup, you might keep a tape in cold storage for years.

Why not have one of those drives off site, and rotate every so often? Carry the drive with you when you swap, so that the original and all backups are not in the same place at the same time. I have three external drives. Originally I planned to keep two offsite, but I don't have an offsite office anymore.
