Restoring 8 month old Active Directory backup


At0mic

Recommended Posts

I’m using windows 2000 server.

Is it possible to successfully restore a backup older than 60 days of the active directory “system state” made using the Microsoft backup program?

I understand that there’s a 60 day limit to which you can restore to due to the tombstones of previously deleted objects. However, I’m thinking about putting the clock back on the server by about 6 months before restoring and then slowly putting it forward a month at a time. There aren’t any other servers in the AD of the backup so there shouldn’t be any complications in that respect.

I will then add more servers to the domain afterwards.

Does anybody know if this is a fool-proof plan?

Thanks

This type of restore can be accomplished by modifying the tombstone lifetime attribute first. The tombstone lifetime attribute is located on the enterprise-wide DS config object. The path for this attribute is:

CN=Directory Service,CN=Windows NT,CN=Services,CN=Configuration,DC=COMPANY,DC=COM

Use the ASDI and set the "tombstoneLifetime" to be older than the backup used to restore the Active Directory.
