Stand alone network backup device. I plan on hooking a low power external USB drive, and using something like rsync over the network so that backups are isolated from the computer I'm backing up. There's already several techniques documented for using rsync combined with "cp -al" to create daily/weekly/monthly snapshots using incremental space; combine this with an appropriate "command=" parameter in ssh's authorized_keys file, and you can have a backup that can run automatically, and that can't be destroyed by malware on the host you are backing up.
- digitalsushi 15y agoI no longer allow myself to use backup solutions I invent. And that's just a calling to my own confidence in my code, but I have lost data that I liked because I did a home brew backup. It's all that logic that makes sure it's still working correctly over time. There are so many devices available for very low cost that provide this exact solution. For me, it's one of those things where it's dangerous to enjoy inventing because I am not a master tool maker.
