Is Backblaze a reliable provider? (infosec.pub)

Hi everyone,

I've started pushing backups of media important to me (family pictures, video etc) to backblaze with client-side encryption.

However, are they a reliable storage provider? I can't help but compare them to something like Amazon who likely has a better chance of maintaining my files but they are so expensive that I don't even bother.

What do you think? Yes, I've heard of 3-2-1, however for now I only have backblaze and a local backup. I'm trying not to spend too much on this.

Thanks!

I think the main thing is for you to try doing a test restore of your data before you need to (and you already have a local backup anyway if your test goes wrong)

That will give you a better understanding of the whole process - they might be 100% reliable in storing data which is totally unusable by you because you've lost your decryption key, weren't backing it up correctly, etc (for example).

I've never really understood the logistics of how to do a test restore.

Do you have to buy a 2nd computer?

You dont need a second computer, just replace the drive with an empty one.

No, you can jusy restore to a second location...it depends on whether everything was backed up, or just a few test files.

I prefer backing up specific folders rather than "everything", so it's easier to test. (I'd just reinstall the OS if that was nuked)

Let's say I want to do a test restore of all my photos. I just rename that folder to simulate that it's been accidentally deleted... then I just do a normal restore - and do a bit-by-bit comparison of the two folders and check it all went well.

I just have a smaller dataset using the same settings, which I try to recover a couple of times/year.

It’s not perfect as recovery exercises go … but it feels safe enough for me.

I really need to do a test restore. I've been backing my NAS up to B2 for about a year now and haven't done one yet.

[–] [email protected] 1 points 1 month ago

Yeah, that was me a couple years ago... I'd read some blogs, watched some yoochoobz and had data going from my NAS to Backblaze... encrypted...so... ok... is it restorable? No idea.
