According to this answer, it is not possible to determine the size of an individual Amazon EC2 snapshot, but they do provide "the total usage and cost numbers for all snapshots in the account."
Where can I see that total?
Background: I'm trying to determine how encryption affects snapshot size. If I encrypt an EBS volume using dm-crypt, will EC2 still be able to compress it when making a snapshot, and will incremental blocks still help for subsequent snapshots?
The only way I could think to figure this out was to check on the size of snapshots, and since they are not available individually, I would have to check the total, make a snapshot, check the total again, etc. BTW I'm still on the Free Tier so some billing info may be suppressed.

You should be able to see that information in the Billing Management Console with the Usage Reports for the Elastic Compute Cloud service. I can select "SnapshotUsage" for the different regions in there.
