Warning: Expired Backup

Active Directory cannot be restored because the backup file's contents have expired.

When restoring a backup file, Active Directory generally requires that the backup file be no more than 180 days old. The limit is 60 days if the AD forest was originally created with Windows Server 2000.

How to Fix This Error

Use a more recent backup that has not expired. Generally the backup must have been made within the past 180 days.

Overriding the Warning Message

If you override this warning message you may encounter problems with lingering objects in Active Directory.

It is safe to override the warning message when you are restoring an entire forest where the backups were all made around the same time (within the same 180 day window). It is also safe to override if there is only one DC for the whole forest (e.g., Small Business Server).
