Windows 2000 System State in backups
There are a lot of reasons to do regular backups, but Windows 2000 adds another one to the list. You must have a current copy of the System State files.
System State files include the Registry, Active Directory, the boot files and the COM+ database. If these files are corrupted or not present you're going to have serious trouble trying to restore the system. The Windows backup utility provides an option to save the System State files and it is a good idea to use the option. The reason is that the System State files have a lot of dependencies in them so they must be backed up and restored as a set.
There are a couple of other wrinkles about backing up the System State. One is that the time between backups of those files cannot exceed the Active Directory's Tombstone Lifetime -- the amount of time deleted objects are kept in Active Directory. Beyond that time limit, the restore utilities will reject all the data as out of date. The default setting on the Tombstone is 60 days, which could be a problem for a system using a generational backup system and attempting to restore from an older tape.
The other consideration is that the System State can only be backed up on the local computer. As Microsoft notes: "You cannot back up (or restore) System State data on a remote machine."
Microsoft covers this in its "Windows 2000 Server Disaster Recovery Guidelines", which is available
