Step 6: Retention
During backup, BDRSuite Backup for AWS takes a snapshot of the target EC2 instances at the scheduled time using Amazon APIs. The snapshots are stored in the same AWS Account and Region of the target EC2 instances.
Each time a snapshot is taken, it corresponds to a restore point (i.e.) a point-in-time from which the backed-up instance can be recovered. With BDRSuite Backup for AWS, you can retain up to 10 snapshots of each target EC2 instance that you backup.
If you set a retention limit of 5 snapshots, then if the backup job is running for the 6th time in its schedule, the oldest snapshot will be deleted to retain only 5 latest snapshots of the target instance.
