Retention for Snapshots

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.

Retention for Incremental backup

If this option is disabled, all the restore points will be retained. If enabled, only the configured number of restore points will be retained.

The following two types of retentions are supported for AWS Backup in the BDRSuite Backup Server.

Basic Retention

Selecting the version based retention will let you enter the number of restore point version you would like to maintain

Selecting the time based retention will let you choose the number of days you want to retain the backup data and you can also enter the minimum number if versions that you want to retain.

GFS Retention

GFS with Full Backup: These will be created using the additional full backup and the synthetic full backup. You can manage weekly, monthly, quarterly or yearly retentions.

GFS with Incremental: These will be created using the incremental backups. With this option you can maintain daily, weekly, monthly, quarterly or yearly retentions.
