Hi Team,

Hi Pradeep Mishra

Possible causes:

There have been some performance issues in Azure Backup service recently that can slow down file recovery.

The recovery process depends on network speed to Azure, so if your internet or firewall is limiting traffic, it can also slow things down.

If files are being recovered from older or archived recovery points, Azure needs extra time to rehydrate that data before download.

To resolve your issue:

Make sure the MARS agent is updated to the latest version.

Try restoring during off-peak hours.

Temporarily disable antivirus scanning on the Azure Backup folders during recovery.

If the slowness continues, please open a Microsoft support case to check if there’s a regional performance issue.

Please let me know if you face any challenge here, I can help you to resolve this issue further
