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.
