Purely a hypothetical for me; I don’t have the means for a VPS or that many files. But in the future, if I’d want to use the 3-2-1 rule with a VPS subscription, what sort of software would I need to ensure that my files can’t be accessed on the VPS and need off-site decryption keys? What kind of setup would allow you to access said files from a different device if the decryption keys are stored locally on it? People who’ve done something similar, how has that gone for you?
Backing up linux is cheating as it can be compressed heavily.
I can backup my whole linux install on Veeam Backup and Replication about 2-3x for the full backup on optimal.
