Azure File Recovery

Question

I have a simple weekly backup running of one directory to test Azure Backup using the MARS aagent.

Today I needed to restore a file, and each of my 3 recovery images when mounted are reporting the file I want is the same date/time stamp. All 3 images mounted report the file I am targeting to have the same date/time stamp:

1. 09/25/21 - shows file datetime 10/13/21 3:46AM
2. 10/02/21 - shows file datetime 10/13/21 3:46AM
3. 10/09/21 - shows file datetime 10/13/21 3:46AM

Any thoughts appreciated.

Hello @R. Paul Warriner - Thank you for reaching out to us and I apologize for the delayed response!

Backup through MARS agent for the first time is always full backup and rest are incremental. An incremental backup stores only the blocks of data that changed since the previous backup.

From the details you provided it seems there was no change occurred on that file which is why you see the file with same date and time.

Ref doc: https://learn.microsoft.com/en-us/azure/backup/backup-architecture#comparison-of-backup-types

If you are sure there were changes made to the file and still the restored file reports the same date and time then we can investigate this further.

Just to isolate the issue, could you please perform some changes to that file and then monitor the backup in the next schedule and let us know if issue persist.
