Using Backup and Restore Services on Windows NT

For instructions on backing up and restoring eDirectory on a specific server rather than the entire tree, refer to Upgrading/Replacing Hardware on Windows NT/2000 and Restoring eDirectory on NT after a Hardware Failure.

The Novell SMS architecture extends to Windows NT. Use any SMS-compliant backup/restore utility to perform backup and restore operations on your eDirectory database located on your NT server. If you want to back up the eDirectory on NT database to a NetWare server, the following components are essential for backing up and restoring:

• The Storage Management Engine (SME) provides the interface for a user to perform backup and restore operations. SMSENGN.EXE is a basic SME provided by Novell for Windows NT. If you are already using an SMS-compliant backup engine, you should continue to use it. SMSENGN creates backups to a set of files---a data file (.DAT) and an index file (.IDX).
• The Storage Management Data Requester (SMDR) communicates between the SME and Target Service Agent (TSA) software. The SME and TSA can be on two different computers or the same computer. If the SME and TSA are on different computers, then an SMDR is required on both machines.

  If you are using Novell SMS on a NetWare network, you should use the SMDR provided with this utility in your regular SMS backup procedures.

• Target Service Agents for NDS (TSANDS) passes requests between the SMDR and the eDirectory database and prepares the data for SME.

  When eDirectory is installed, the SMDR and TSANDS are set up by default as a Windows NT service that is always available. If it is not available (service can be verified in Settings > Control Panel > Services), start W32SMDR.EXE located in the NDS\SMS directory.
