Immutable backup for important data (self.selfhosted)

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

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

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.

My goal is that if for whatever reason, my homelab is compromised, I will be able to at least restore my important data.

If i can modify the data on the other end, but cannot from my proxmox, then its fine.

I would like a offsite solution in the future, but for now it's going to be a cloud for data blob only.

Borg backup?

[–] Croquette 1 points 3 months ago (1 children)

Never heard of it, but I will look into it. Thanks

Borg append only seems like the way to do this easily

[–] [email protected] 1 points 3 months ago

restic can run append-only, too. It's more about the remote not allowing deletions.
