I have a server running Debian with 24 TB of storage. I would ideally like to back up all of it, though much of it is torrents, so only the ones with low seeders really need backed up. I know about the 321 rule but it sounds like it would be expensive. What do you do for backups? Also if anyone uses tape drives for backups I am kinda curious about that potentially for offsite backups in a safe deposit box or something.
TLDR: title.
Edit: You have mentioned borg and rsync, and while borg looks good, I want to go with rsync as it seems to be more actively maintained. I would like to also have my backups encrypted, but rsync doesn’t seem to have that built in. Does anyone know what to do for encrypted backups?
I have my BD/DVD/CD collection backed up to S3 Glacier. It’s incredibly cheap, offsite, and they worry about the infrastructure. The amount of Hard drive and infrastructure space you’ll need to back up early that amount will cost you the about the same give or take. Yes it’ll cost a bit in the event of a catastrophic restore, but if I have something happen at the house, at least I have an offsite backup.
How much does Glacier cost you? Last time I checked, some hosts had warm storage for around the same price, at least during Black Friday or New Year sales.
