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?
Rsync is available out of the box in most linux distro and is used widely not only for backups, but a lot of other things, such as repository updates and transfers from file hosts. This means a lot more people are interested in it. Also the implementation, looking at the source code, is cleaner and easier to understand.
I think you should consider that not all files are equal. Rsync for me is great because I end up with a bunch of disks that contain an exact copy of the files I have on my own server. Those files don’t change frequently, they are movies, pictures, songs and so on.
Other files such as code, configuration, files on my smartphone, etc… are backup up differently. I use git for most stuff that fits its model, syncthing for my temporary folders and my mobile phone.
Not every file can suit the same backup model. I trust that files that get corrupted or lost are in my weekly rsync backup. A configuration file I messed up two minutes ago is on git.
Thanks for elaborating, the part about the pictures and movies not changing makes a lot of sense actually. Thanks for sharing!
