SMS backup and restore operations

The following diagram shows how a typical backup session is set up and established:

A typical backup session

1. To be able to backup and restore files on a UnixWare system, a NetWare server's name must appear in the unixtsa.conf(4) file on the UnixWare system. The protocol that the NetWare server will use to attempt to connect to the UnixWare system must also be listed next to the NetWare server's name.

2. Then, the tsad(1) daemon must be started on UnixWare. See ``Configuring UnixWare for backup/restore from NetWare''. This daemon listens over the network for connection requests from backup engines running on the NetWare servers listed in unixtsa.conf.

3. After making sure the NetWare server has the appropriate protocols available, load at least the TSAPROXY NLM and then load the backup engine (such as SBACKUP). See ``Configuring NetWare for UnixWare backup/restore''.

4. Once the backup engine is loaded, the backup or restore operation is under the control of the backup engine. Through it, you send a request to the UnixWare system.

5. The tsad daemon receives it, and launches a tsaunix(1) process.

6. The backup engine and the tsaunix process now cooperate to perform the operation you request. Data is backed up onto the media you select throguh the backup engine on NetWare. The SBACKUP software included with UnixWare can access any NetWare device known to the server on which it is running.

The restore process works much the same way, with that backup engine and a tsaunix process cooperating to restore data from the backup media. See ``Restoring backup onto UnixWare''.
