What is AMI Auto Backup?

The AMI Auto Backup feature allows data persistence within an Elastigroup. This feature creates an image from the running instance in the Elastigroup and updates the group with the newly created image. By default, a record of 3 images taken by the AMI auto backup are kept, these will be the 3 latest images. Upon Spot replacement, Elastigroup will recover from the latest image automatically.

The image is taken from the latest launched instance and will be applied as AMI to any future launched instance in the same Elastigroup until the next backup.
