Point in time (PIT) policy - AWS Elastic Disaster Recovery

Point in time (PIT) policy

AWS Elastic Disaster Recovery allows you to select the number of days for which point in time snapshots are retained through the Point in time (PIT) policy field.

You can select to save PIT snapshots for 1 up to 365 days. Saving PIT snapshots for more days allows you more recovery options, but also results in increased costs. Learn more about Point in time.

Important

The PIT policy must contain exactly three rules: one for MINUTE, one for HOUR, and one for DAY. The snapshot frequency intervals and retention durations for the MINUTE rule (interval=10, retentionDuration=60) and HOUR rule (interval=1, retentionDuration=24) are fixed and cannot be modified. Only the DAY rule's retentionDuration is configurable, with a value from 1 to 365 days.
