Questions on backing up to S3 Glacier Deep Archive.
Questions on backing up to S3 Glacier Deep Archive.
Hi everyone. I was considering backup options to Glacier Deep Archive, and wanted to know:
- Which software do you use to encrypt client-side, obfuscate, compress and deduplicate the data before you send it to S3?
- What is the difference between
Restore Requests (bulk)andOutbound data transferand which one will I be using when I want to pull my data from AWS?
I'll be storing approximately 8TB or so of data, which is why I was looking at inexpensive ways to back it up other than buying an HDD outright.
Thanks!
Recently I looked into the same thing, since AWS caught my eye with their apparently ridiculously low prices. Then I found this (presumably indepdenant) review, that changed my view on things: https://b3n.org/b2-vs-s3-nas-backup/
After reading that, I won't go with AWS. I'm currently considering to abuse the OneDrive Office Family plan, which costs 99 $ a year for 6 TB of storage (split across 6 accounts), which comes down to 1,40 $ per month per TB. A price that I have not seen beaten by other storage / backup providers.
The problem with AWS is that one need to bring all storage from glacier to regular S3 (which is quite expensive), and then their egress costs are massive. I read more about it and completely agree that AWS is not worth it at all when pulling data in.
However, BackBlaze is quite expensive. I'd be paying $50 for my storage, which is simply not how much I'd like to pay. At this rate, I'd get a 10TB Ironwolf drive in an enclosure from Amazon for my cold storage.
TBH, I was looking at other providers, and Dropbox looks much less expensive at $20 for 9TB. It's a lot more than the 8TB I thought I'd be able to get away with for Glacier storage, but at least it's not $50. I will take a look at scaleaway, but I simply trust the bigger players to be around and keep my files safe than the smaller companies.
Edit: Scaleway seems less expensive than Dropbox with their glacier option. I really hope I can trust this company because this is an excellent price and I might even be willing to pay as much if it can be kept secure and safe. Now, I just need to read more about the value proposition of Dropbox vs Scaleway Glacier.
Regarding Dropbox: Where are you seeing 9 TB for 20 $? I'm in the EU so my pricing may vary, but all I can see is the Business plan for 16 € per month per user, with a minimum of 3 users in the plan, making it cost 48 € instead. Do you have access to something else?
Regarding Backblaze: Agreed that 50$ a month is a rough bill to pay, that sums up very fast if youre counting across the years. But their storage is also a lot more reliable than one single hard drive stored in a bank locker, with them always checking their arrays and replacing aged drives.
Regarding Scaleway: If im reading their pricing chart right, it would cost roughly 2 € / month / TB for glacier storage, and 9 € / TB when restoring from glacier to standard storage? A big questionmark for me is how ingress works. If I'm using this for backups in case of total system failure, i'll want to upload differential backups (borg/duplicati) every couple days. How is that going to work with pricing, is that all running through standard storage driving up monthly cost, do I have to manually manage file history and deletion of older stuff or does my backup software handle that? Plus, you loose out on the instant file access that you get with Backblaze, or with something hacky like Dropbox / Onedrive. I'm still undecided which I value more, money or fast access.
That class of storage is very expensive to get your data back. Buying a drive will be cheaper.
I think that people would be using the service as a last resort, like when all other local or physical offsite backups fail.
In that sense, the cost to recover shouldn't be the main factor when considering it.
Wait, I'm looking at the data retrieval cost (bulk request) and it says it's priced at $0.0025 per GB? That comes out to about $21 for a retrieval! Am i missing something important?
Take a look at the calculations here https://www.arqbackup.com/aws-glacier-pricing.html
It explains it a bit better. You have to factor in how many requests you need too. So both file sizes and amount of files.
Lots of answers in the comment about this particular storage type/vendor. Regardless, to answer your original question, rclone. Hands down. If you spend 30-60 minutes actually reading their documentation, you are set and understand so much more of what’s going on under the hood.

I don't encrypt before I push to S3. Probably bad practice on my part. I just rely on AWS encryption to secure my data. My backups are low-risk (imo). That said, I lock down the bucket so that only my account can access the objects. Compression I use
tar cjf(bzip). Protip: Once the tar file is made, runtar ljf $archiveFile > archiveFile-ls.txtand store the resulting file along with the tar file in standard storage. That way you know what is in the archive. -
Both.
Restore Requestsis to copy the data out from Glacier into Standard storage. Note that I said copy. When you perform a restore, your original object stays in glacier and AWS creates a copy to somewhere in S3 that you specify. Once the restore is complete, you can then download the copied object like any S3 object, triggering theOutbound data transferfee.
Thanks, I'll keep that in mind. I'd encrypt everything client-side since I don't want anyone to know what I'm storing; including the Cloud provider.

I'm using it too and even the current prices are reasonable (especially if you consider there's no other fees, no transfer, no ingress, no egress, ...). If you put it in S3 glacier and you ever have to restore a relevant chunk of your data (or god forbid, want to do periodic testing of the backed up data) then you'll be paying quite a bit of fees.
