Figure 2-1. EBR Software on Client Workstations and Servers

Creating the EBR Service

Reboot the server to start the portmapper process that EBR clients and servers use to connect with each other.
Create and configure the EBR service using Banyan's MSERVICE or StreetTalk Explorer management tools.
Start the service.

EBR Components

A portmapper process, started at server boot time, that EBR agents and services use to find each other on a network.
A service manager that allows the VINES server service to start, monitor, and stop the EBR agent.
A remote execution service that responds to backup requests from an EBR service. These requests include backup criteria, such as which disk volumes to back up and what data should be backed up (that is, all data, data that has changed since a certain time, and so on), as well as the identity of the EBR service making the request.
Save programs that scan the server' s disks and, applying the backup criteria supplied by the EBR service, generate backup data that they send over the network to the EBR service that made the request.
A recover program that lets you browse the contents of an EBR service' s on-line directory of data backed up from this server and select items (files, directories, services, and so on) for recovery. The recover program then sends this recover list to the EBR service, which locates the selected items on backup volumes (tapes), then streams the data back over the network to the server that made the recover request. The recover program on this server then reconstructs this data stream into files and directories and writes them onto the server' s disk.

A Network Save and Recover Daemon (NSRD) that sends save requests to the agents on its client list and responds to recover requests from those agents.
An index daemon that manages the on-line file and media indexes from which the agents' recover programs select data for recovery.
A media manager that writes data to and retrieves data from backup volumes (tapes).
Media utilities that can be used to recover indexes and data directly from tapes in the event of a crash or other disaster.

EBR Service Optional Parameters

Location of the EBR service data directory
Trusted server names

Backing up the EBR Server

Installed and created an EBR service on a VINES server that has an 8mm tape device. (8mm is the default tape device for EBR. If your server has a 4mm or a QIC device, you must first use EBR Administrator's device configuration dialog box to tell EBR what type of device the server supports. See Chapter 4 for more information.)
Installed the EBR Administrator, EBR, and EBR Scheduled Backup programs on a VINES workstation running Windows.

1. Insert a writable tape in the server's tape drive.

2. Choose Label and Mount from the Media menu. The Label and Mount dialog box appears:

Figure 2-2. Label and Mount Dialog Box

3. Accept the volume label provided, and the Default media pool. Click the OK button or press [Enter] to begin labeling the tape. The Devices status window shows that the tape is mounted.

4. Choose Groups from the Client menu.

A group is a collection of (one or more) EBR clients scheduled for backup starting at a specific time.

5. In the Groups dialog box, highlight the Default group and click the Edit button. The Edit Group dialog box appears:

Figure 2-3. Edit Group Dialog Box

6. Change the Autostart field from Disabled to Enabled. Leave the Start time at 3:33 and Client retries at 0. Click the OK button or press the [Enter] key.

7. Choose Group Control from the Client menu, or click the Group Control button on the speedbar. The Group Control dialog box appears:

Figure 2-4. Group Control Dialog Box

8. Highlight the Default group, and click the Start button to start backing up the group immediately, rather than at 3:33 a.m.

Adding a Client

1. Select Setup from the Client menu. The Clients dialog box appears, displaying the names of all clients already known to the EBR service on redwood. Note that redwood is on the client list.

Figure 2-5. Clients Dialog Box

2. Inside the Clients dialog box, click the Create button. The Create Client dialog box appears:

Figure 2-6. Create Client Dialog Box

3. Enter the name of the client into the Name field. If the client is a VINES server running an EBR agent, the name is the server' s hostname. For example, if the server' s StreetTalk name is Redwood@Servers, enter redwood in the Name field. (You may use upper and lowercase letters or a combination of both.)

If the client is a VINES workstation running EBR or Scheduled Backup, you must pick a name for it. The name can be any combination of letters and numbers up to 16 characters long. Once you have selected the name, you must ask the workstation' s primary user to log in on that workstation, run the EBR program, and type this name in at the Client Name dialog box.

In the Schedule field, use the default schedule. Later, you may decide to use one of five provided schedules, or create a custom schedule. Accept the default Browse policy and Retention policy for now. If the client is a VINES server, you may also use the default Directives. However, if it is a Windows workstation, you must select DOS Standard Directives from the directives list.

In the Group field, make sure the Default group box is checked.

4. Click the OK button or press the [Enter] key to save your work.

Tip: After the backup has completed, check to see that it was successful by bringing up the Group Control dialog box again, and clicking the Details button.
