Backing up to Amazon Glacier: What is it and How Does it Work? Synology and ARQ

This video is a snippet from a Weekly Wrapup episode that you can find here: lon.tv/ww231 . A few viewers asked about how to use Amazon's Glacier backup service on a NAS device. I thought I would explain exactly how the service works and why it works for my purposes.

Amazon S3 Glacier automatically encrypts data at rest using Advanced Encryption Standard (AES) 256-bit symmetric keys

[@grantcivyt]

Amazon encryption protects your data reasonably, but obviously Amazon can decrypt, which means you have to trust their employees. You can also expect them to decrypt for whatever authorities may approach them. Lastly, you have to worry that a hacker could conceivably obtain the decryption keys and access your data.
Probably all fine for most people, but I prefer to avoid those security holes. Either way it's good to be aware.

Very nice vid, thanks for all the explanation. I am doing the same as a kind of disaster recovery, so I upload my pictures and recorded videos, my documents and some other files. You need to be careful, when you want to backup lots of smaller files. If you leave them unprocessed and back up the whole directory, you will get charged more for the number of requests. What I do: I first run a scheduled task, that creates a zip of every subfolder in the photos folder into a backup photo folder. I then back up that zip container with glacier. Like that, I only have a certain amount of files and my monthly fee for ~150GB of data is less than €0.60. pretty cheap last resort recovery option if everything else fails.

Thanks. I liked that you went through your bill as it gives me a sense of what to expect cost wise. I have about 20k/1.5TB photo's/video's to put in deep storage for disaster recovery. So I now have a better sense of what this approach would cost. I know Synology seems to be avoiding offering an option to backup to AWS Glacier Deep Archives. I guess C2 customers would leave en mass. So I've been trying to research ways to do this but as a rookie, not sure if I am about to do something that would result in a huge bill. The best advice I've found is use Synology Cloud Sync to a S3 Standard Storage Class and then use a Lifecycle rule to transition to Glacier Deep Archive a day later. However, I'd love it if someone with more knowledge than me went though this in the detail of this video (hint hint :) ).
