Restoring from MARS to different domain

Question

We recently needed to create a new domain due to a outage with our former domain. Single server DC and file storage SMB environment... Long story... ultimately we formatted the server and started fresh with a new AD install - since the SID's don't match what was backed up in Azure, we are now running into issues as the mount point is read-only to restore the files from. Any way to mount the restore job in a read-write option so we can re-apply the permissions and get that data restored down to the new domain?

Hello IT Admin,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Since the restore point is mounted as read-only, you cannot change a mounted point to read-write.

Instead, you can manually copy the files to a different writable location (such as another volume, file share, or local disk). Then use the Instant Restore feature to mount a writeable recovery point snapshot as a recovery volume. You can then explore the recovery volume and copy files to a local computer.

You can refer to the below MS Article for better understanding:

https://learn.microsoft.com/en-us/azure/backup/backup-azure-restore-windows-server

And as you mentioned, if your primary server got down/lost where the backups were taken, you can restore the backed-up data to an alternate machine (in New Domain) by using the same passphrase that you provided during registration.

Here is the necessary steps to follow this method: https://learn.microsoft.com/en-us/azure/backup/backup-azure-restore-windows-server#use-instant-restore-to-restore-data-to-an-alternate-machine

in this way you can restore the data to the new domain.

Hope this helps!

Please reply if you have any further queries.
