Details

Body (from Message Center)

Starting May 11, 2026, the default backup retention for Power Platform environments will be changed from 28 days to 7.

All environments will continue to be automatically protected with a 7‑day default backup, ensuring reliable recovery for day‑to‑day scenarios. For customers with higher compliance, governance, or operational needs, enabling Managed Environments unlocks the ability to extend backup retention up to 28 days, putting control directly in administrators’ hands. Managed environments will support up to 28 days of backup retention if increased by administrator; otherwise, the default is 7 days.

How does this affect me?
This change impacts the point in time restore window available for active environments and will not impact deleted environments. Currently, when a production environment with Dynamics 365 apps is deleted, the data will continue to be restorable for up to 28 days and when a production environment without Dynamics 365 apps is deleted, the data will continue to be restorable for up to 7 days. These are not changing.

For users with higher compliance, governance, or operational needs, enabling Managed Environments can extend its backup retention up to 28 days.

What action do I need to take?
This message is for awareness, and no action is required.

For environments that you want to extend the backup to 28 days, you will need to enable managed environment and change the backup retention period.
