ec2-snapshot-replicator

Replicate snapshots to another region with delayed deletion.

$ gem install ec2-snapshot-replicator

$ ec2-snapshot-replicator start \
    --source-region=ap-northeast-1 \
    --destination-region=us-east-1 \
    --owner-id=123456789

• --source-region: region name where snapshots are replicated from (e.g. ap-northeast-1)
• --destination-region: region name where snapshots are replicated to (e.g. us-east-1)
• --owner-id: account ID of owner of snapshots
• --once: replicate once and exit (default: false)
• --delay-deletion-sec: if the source snapshot is deleted, the replicated one in the destination region will be deleted after delay-deletion-sec. (default: 604800 = 1 week)
• --interval-sec: interval seconds of loop (default: 600)
• --config: load configuration from YAML file (optional)

$ ec2-snapshot-replicator start \
    --delay-deletion-sec=3600 \
    --interval-sec=600 \
    --source-region=ap-northeast-1 \
    --destination-region=us-east-1 \
    --owner-id=123456789

If the above settings are provided:

• loop the following:
  • If a snapshot in the source region is not found in the destination region, copy it to the destination region and create SourceSnapshotId tag.
  • If a snapshot in the destination region is not found in the source region, create DeleteAfter tag which is (now + 1 day) in seconds since unix epoch.
  • If DeleteAfter time of a snapshot in the destination region is over now, delete it.
  • Sleep 10 minutes
