Immutable backup for important data (sh.itjust.works)

submitted 3 months ago by [email protected] to c/selfhosted

21 comments fedilink hide all child comments

Hello,

I am looking for recommendations for a service provider of immutable backup that has options for a homelab user.

My research has led me to services with expensive options, or no pricing at all unless you ask for a quote.

Thank you

Backblaze B2 has the option: https://www.backblaze.com/docs/cloud-storage-object-lock

Cheap storage too.

I use B2 for my backups with object lock on

Thanks for the information, I will look into that.

I use backblaze storage with Kopia, which supports using object lock. Every time a backup is made the objects for it are locked for a configurable amount of time. I use 30 days, so an attacker would have to compromise my backup software for a month before being able to erase my backups.

I like the thought of having timed backups to keep the costs lower by pruning the olds backups.

Also only differences are stored, so if your files don’t change much each backup costs very little. I keep hundreds of backups for the previous year of changes, and it uses less than double the amount of storage the files take up. You can also enable compression, which I do, so it’s even smaller.
