| Cynthia,
Those files will be automatically created if you have to restore a system state. It does not back them up because the files themselves are expendable. When the services start, if those files do not exist, they are created.

TSM is backing up the system state successfully, according to the log files, however I was under the impression that the files I listed (ntfrs.jdb, etc) are not included in the system state. Therefore, wouldn’t a ntbackup, or TSM for that matter, of the system state be useless in this regard?

TSM can do system state backups (which will include AD,) but generally you will find most robust installations of TSM will have a scheduled NTBackup of the system state as past versions of Tivoli 5.x have had hanging problems with system state backups. As of 5.3-5.5 there aren’t any issues with those backups. Usually I have done both, but configured TSM to skip system state if there is a problem. Note that TSM is a scripted piece of software, so you might need to bring in an experienced TSM consultant to setup the system state skip.

Cynthia,
The 2 files listed are open and cannot be backed up using a file level backup type of backup.
When the System State is being backed up then you have backed UP the AD – unknown how this is called within TSM but TSM need to be AD aware (like it must be Exchange aware to make an online Exchange backup).
AD is, like Exchange, a JET Database and has open files during its operation.
The edbtmp.log file is a template file for the actual transaction log file(s) and the edb.log is an actual log file.
See http://support.microsoft.com/kb/247715 for more info.
Bottom line, if the backup product understands AD then you should use its feature of “backup AD”, if it does not understand AD and you can only use a file level backup then I suggest you run a scheduled version of ntbackup on a domain controller to make a backup of the system state and then backup this file using TSM.

Subject: [ActiveDir] FRS Database Not Backed Up
TSM is the default backup solution for our environment. We get a daily backup status report for all servers we manage, which includes the DCs. When investigating a “failed 12” backup status (which basically could mean anything from “backup missed some files” to “backup missed an entire drive” to “TSM made VSS freak out”) I noticed that TSM regularly fails to back up files in the %SYSTEMROOT%\ntfrs\jet directory…specifically nftrs.jdb, \log\edbtmp.log and \log\edb.log. I combed through enough Google results to find out that those files are not included with the SYSTEMSTATE backup, but I’m still trying to find out if
a) they could/should be excluded from the backup and…
b) …if not, how to close them properly so that they can be backed up.
Could anyone offer help on the above?
