Answer 1

Hi,
If i didn't misunderstand you ,you mean recover the DCs from the backup, right? If i misunderstand you ,please let me know.

Based on my understanding , you backup the servers at different times you if you restore the server from the backup, they will be back to the time the server be backup.

Not sure how many DCs do you have , but we don't need to recover every DC from backup.
Just select one RWDC replicate from BACKUP and make other DCs replicate from it.
For more details you can refer to this article.

Hi，

Sorry for the late reply, a little busy recently.

Based on my understanding, your issue is that we can't recovery from the backup over 45 days. If we use backup schedule, this may due to "Automatic disk usage management", Windows Server Backup will automatically reuse the space occupied by older backups when creating new backups.

If the backup over 45 days is deleted, this may due to there's no enough free space to create new backups.

Please check the following article for detailed information：

Besides, we may use the wbadmin command to set the oldest backup settings:
