Backup AWS #Volume (to #S3 or similar).

Problem: I have some old instances, and even worse, old data volumes, that needs to be stored for some time, then removed. Very likely noone would look at it again.

EBS costs (per TB) - 110$
EBS Snapshot - 55$
S3 IA storage - 12,5$

90% cheaper!

Is there any reasonable way to backup this to S3 other than mounting the volumes and dd (bit-copy) manually?

    EBS Snapshots are compressed and to some extent deduplicated against others, so you should look at your cost and usage billing detail records to see how much these snapsnots actually cost. At last check, my actual snapshot charges were a small fraction of what you would anticipate if you assumed a snapshot of a 100 GB volume consumes 100 GB of snapshot storage. It doesn't.

  • If you want to access the data on the EBS volume you need to mount it. I wouldn't backup using dd, I'd probably just upload the useful data to S3, perhaps in a zip file. I wouldn't do anything with a boot volume, too much risk of not being able to boot it again.
