I would like to use a cloud backup service on my home server. I am a complete beginner. I purchased a subscription for Proton Drive, but it looks like that just won’t work. Is there a secure cloud backup that works well on Linux? Bonus points if there’s a way to use proton drive. Extra bonus points, if I can set it up for automatic backups through a GUI.
Any cloud is a secure backup on Linux if you use rclone crypt :)
It works with Google Drive, Dropbox, One Drive, and countless others to create an encrypted cloud storage, where the cloud provider can never view your file contents.
I’ve loved using Backblaze B2 buckets. Been using them for years and it’s very reasonable. Many different backup titles can use them.
Maybe consider a Hetzner storage box. They support borg, restic, rsync and probably more, there’s no ingress or egress fees and you get unlimited traffic. Very nice for off-site backups if, like myself, you’re on a limited budget.
You can try rclone, but their Proton Drive integration is in beta
https://rclone.org/protondrive/So there’s a storage protocol called “S3” (I wanna say it stands for simple scalable storage?), first created by Amazon for AWS. Many types of software, including backup programs, have been designed to use it as a storage backend. There are now many S3 compatible providers, last I looked the best value was backblaze B2.
You need a backup program with end-to-end encryption, S3 compatibility, and whatever other features you like. I use restic but it’s CLI only, there’s also borg backup and many others.
If you encrypt locally with a good key, you don’t have to trust the remote storage provider. They just see a bunch of meaningless noise. Just don’t lose the key or your backup is useless.
Run a transparent encryption program and buy a Google drive subscription of 2TB for a year for $100.
I personally use restic for local backups which then get synced with rclone into a Hetzner Storage Box.
R2 has no ingress or egress fees
