Need solution for backup cleanup

Siva 736

Hi Team,

We could see that post backup stop with Immutability, it is still with the policy and it is getting expired as per the retention, but the last restore point is not getting deleted and we need to manually delete the backup every month. In order to avoid that monthly activity do we have any further step or suggestions from ms to get that everything deleted as per retention without manual intervention.

Mostly the last restore point for vm is bit getting updated with expiry date, so what will be the ms recommendation on this issue?

Hi Bharath,

Apologies for that, Type is Azure VM and SQL.

If you see the azure docuementation, when you are stop backup with retain data as per policy, it is getting deleted as per policy but the final restore point is not deleting.

It is like we need to check every month once and delete manually post retention. so we need that different way to make it automate or MS have any solution for this behaviour?

Just getting questions..
After retention period, why we need to keep the recovery points? what is the use of backup policy and its retention settings?

Hello Siva, Recovery points are time‑based snapshots of your data. Even after the retention period, older recovery points may be required for audits, compliance needs, or recovery from issues that affected newer backups.

Backup policy defines how backups work. A backup policy defines When backups are taken, how long recovery points are kept and Which retention layers apply

Microsoft documentation explicitly states that a backup policy defines the schedule, frequency of recovery point creation, and retention duration.

Hi Bharath,

We understand about the backup schedule policy, only concern is last restore point is not deleted irrespective of retention period, we have soft delete and enhanced soft delete option also for keep last data post deletion for some time. if required you can allow us single recovery point retention modification, that will be great.

Hello Siva, The last recovery point is intentionally retained by design as a safety measure to ensure at least one usable restore option always exists. Soft delete and enhanced soft delete further protect against accidental or malicious deletion.

While some platforms allow limited, exception-based retention adjustments for the final restore point, these are typically restricted due to recoverability risk.

This behavior is by design and serves as a safeguard to ensure that at least one usable restore point always exists.

Safety net Prevents scenarios where all recovery points are purged, leaving no option for data recovery.

Soft delete Retains backup data for a defined grace period after deletion, enabling recovery from accidental deletions.

Enhanced soft delete Extends this protection further to guard against malicious or unintended removal of backups.

Because of these protections, the final restore point is typically excluded from standard retention cleanup.

Hello Siva, Azure automatically deletes expired recovery points based on the retention policy. However, the last hardened (vaulted) restore point and the most recent restore point are kept permanently to ensure recoverability. The final restore point is not deleted automatically after the retention period. If you no longer need it, you must delete it manually. This behavior is by design and is intended to prioritize data protection over automatic cleanup.

Hello Siva, It sounds like you're dealing with some nuances around Azure Backup retention and the deletion of restore points. Here’s what you can do to set up a more automated cleanup process for your backup restore points:

Check Your Backup Policy: Ensure that your backup policy is correctly configured for your retention requirements. If the last restore point is not getting deleted, it might be due to incorrect settings in your backup policy.
Retention Rules: According to Azure Backup's guidelines, retention rules dictate how long recovery points are preserved. If you have extended retention periods, older restore points won’t be deleted until they fall outside this window. Review your current retention settings and adjust them to meet your needs.
Soft Delete Feature: Ensure that the soft delete feature is properly configured for your backups. This feature retains delete operations temporarily, which means that deleted restore points won’t be purged until the retention period has expired.
Automating Cleanup: Unfortunately, if you're facing challenges with the last restore point not deleting automatically, you may need to check Azure's documentation for additional scripts or automation tools that can facilitate this (e.g., Azure CLI scripts).
Manual Deletion: If all else fails, and until you can automate this, unfortunately, you may still have to delete the restore points manually as you are currently doing.
Consult Microsoft Documentation: For more detailed steps and to ensure everything is set up properly, you can refer to the following resources:
