Overlapping continuous backups on the same resource - AWS Backup

Overlapping continuous backups on the same resource

In general, you should protect each resource with no more than one continuous backup rule. This is because additional continuous backups are redundant. However, as you scale up your backup estate, it is possible for multiple backup plans, rules, and vaults to overlap on a single resource. AWS Backup handles these overlaps as follows.

If you include the same resource in more than one backup plan with a continuous backup rule, AWS Backup will only create a continuous backup for the first backup plan it evaluates. It will create snapshot backups for all of the other backup plans.

If you include multiple continuous backup rules in a single backup plan:

  • If your rules point to the same backup vault, AWS Backup only creates a continuous backup for the rule with the longest retention period. It disregards all other rules.

  • If your rules point to different backup vaults, AWS Backup rejects the plan as not valid.
