I found today that Amazon S3 has a really cool one-click backup, where you can set things to back up regularly to Amazon Glacier.
And Amazon DynamoDB also has this thing where you can set it to automatically back up to a table in another region.
You can also set DynamoDB to back up to S3.
Glacier is apparently like a substitute for magnetic tape, without the inconveniences of tape. Takes a while to restore, as well. Pretty cool idea. I wonder what competition exists in this space, currently. A cursory search suggests none.
Glad this is there. It’s pretty essential.
