问题
In the past few months our snapshots backup volume increases and hence our monthly bill in amazon EC2. Now i wanted to delete some of our old EC2 snapshots. So here is the question:
How to find all the snapshots created from a single Volume ID using EC2 command line tool? I tried ec2-describe-snapshots but this list all the snapshots. We have lots of snapshots and it is very difficult for me to note them down one by one.
回答1:
aws ec2 describe-snapshots --filters "Name=volume-id, Values=vol-1234,vol-5678"
to get the values of only the snapshot-ids and the corresponding volumes:
aws ec2 describe-snapshots --filters "Name=volume-id, Values=vol-1234,vol-5678" --query 'Snapshots[*].{SnapshotId:SnapshotId,VolumeId:VolumeId}' --output table
Refer : http://docs.aws.amazon.com/cli/latest/reference/ec2/describe-snapshots.html
回答2:
Do ec2-describe-snapshots --filter "volume-id=vol-12345".
Well documented.
