I currently have 3 machines backing up to b2 directly, and I would like to alter the setup so that those machines back up to an onsite SFTP server instead, which then copies the backups to B2 so that I can have identical and efficient onsite and offsite backups.
I’m thinking it might be possible to create a new local storage on the SFTP server and copy down from B2, but then will the client machines be able to back up directly to it? Or will they need to run the copy commands themselves? Ideally I’d like the SFTP server to run the copy operations rather than the clients, but I’m not sure if that’ll be possible based on other forum posts I’ve read.
It would be helpful if someone could give me a step-by-step/ELI5 explanation.
