aws-auto-snapshot

NOTE: As of October 2019 AWS Lightsail supports automatic snapshots with a seven day retention period. It is recommended to use the lightsail version instead of this tool if possible. Details can be found here.

aws-auto-snapshot is a set of tools that help to create snapshots for

• EBS volumes
• Lightsail instances

The so-called snapshotter lets you create those snapshots. By default it will snapshot all running lightsail instances in the account and all EBS volumes that have a special backup tag.

It can be configured how long snapshots are stored, i.e. when the tool will prune them.

Generally, you will want to run the tool on a regular basis, e.g. once a day, via, for example, a cron job. At gridX we run it as a cronjob in our Kubernetes cluster.

Metadata about each snapshot can be stored in a datastore. Currently, only DynamoDB is supported as datastore.

If metadata was written to a datastore, this can be used to automatically restore the latest snapshot of a resource. This is currently only supported for the EBS volumes, though.
