Both S3 and Google offer file storage where you can set that it can't be overwritten or deleted until a certain date. So you get the best of offline and online

I imagine it to be more expensive than both running disks or tape backup yourself.

  AWS S3 Glacier is dirt cheap as long as you don't need to restore. AWS S3 Object Lock is about $.02/GB, Glacier about $.004/GB. If you have a decent connection, cloud storage is hard to beat.

    > AWS S3 Glacier is dirt cheap as long as you don't need to restore. What does that even mean? If I don't have to restore, /dev/null will be even cheaper!

    It’s been a while since I looked further into this, but are you accounting for data transfer fees as well? I recall that being a non-trivial cost.

      I don't know the costs of data egress for Glacier, but standard S3 is around $.09/GB. Considering that most backups are never used, the cost of data egress is usually pretty minimal in the grand scheme of things.

    Hmm, the marketing for glacier says "starting at $1 per terabyte per month" (at the top of https://aws.amazon.com/glacier/ https://aws.amazon.com/glacier/) but the pricing page seems to quote $.004/GB = $4/TB as the cheapest storage in the US and the random selection of other regions I clicked on. At $4/TB why would I pick this over blackblaze B2 which is $5/TB (pretty basically the same) but works like live normal block storage instead of taking hours to retrieve (or minutes if you pay extra)? Moreover the download cost from glacier to AWS is $0.02/GB plus at least $0.003/GB in retrieval costs (or $0.09/GB to $0.05/GB to the internet), while the download cost from blackblaze to the internet is only $0.01/GB and is free if it's to many of the members of the bandwidth alliance (notably including cloudflare). I'd have to be looking at many petabytes of data before the miniscule cost savings of glacier data that I actually don't touch is worth it. Or I guess if the data was already in AWS and the egress to blackblaze was going to be too expensive to be worth it.

      S3 Glacier Deep Archive is $0.00099/GB which comes out to $1/TB. AWS also doesn't charge you to transfer from Glacier to any AWS service as long as you're staying in the same Region. Does Backblaze B2 have multi-site redundancy? We have our S3 buckets automagically replicated to a different AZ. That was a must have since we're highly regulated, and our backups need to persist for over 7 years.
