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
How immutable do you need?
S3 offers a flag that prevents modification or deletion for a set period, and afaik basically every S3-compatible provider offers that.
I use that along with a lifecycle rule to maintain my backup buckets on iDrive.
If you need a ‘you cannot touch this and the provider has no way of allowing it’ then you’re talking specialized corporate talk-to-a-sales-person-for-a-quote, as you found out.
Edit: if you don’t need cloud, there’s options for WORM media from the humble BluRay to fancy SSDs that don’t allow deletion.
I use Backblaze B2, but stored in an encrypted Restic container, set up using this guide:
Restic has been great for automating backups, and even letting me mount the encrypted storage to grab individual files. I like doing it this way since I don’t have to trust Backblaze isn’t reading my data - I know for sure that they can’t.
Performance of storage that is both remote and encrypted is about what you would expect, but I don’t need access to the data unless something bad happens.
