This chapter introduces you to EBR. Once the system administrator has installed it on your system, you can start becoming familiar with EBR.
If the software is installed, you should have a program group called "EBR" inside Program Manager, containing the following two icons:
EBR is a backup and recover program that allows you to save data over the network and to recover data that was saved manually or as part of a regularly scheduled backup. Use this icon for manual backup, data archiving, file verification, or any recovery request.
Scheduled Backup makes your system available for regularly scheduled backups. This program can be placed in your StartUp group for fully automated backup.
To start EBR, double-click on the EBR icon.
The EBR Main window appears. Labels identify each window element.
The title bar contains four standard Windows elements. From left to right they are the control menu box, active or inactive title indicator, minimize button, and maximize button.
Initially, the menu bar has three choices that are dimmed: Tree, View, and Window. When you select an Operation, such as Backup or Recover, these choices are enabled, and Operation is dimmed.
The speedbar provides buttons for common operations. When you select an Operation, the buttons change according to the operation. The speedbar and status line can be hidden and displayed again using the Options menu.
On the status line there are three boxes: the EBR server name, the EBR client name, and a brief help message that appears while you are selecting menu items.
Note: A system administrator decides which EBR service will back up your workstation. Before the EBR program can operate, it must recognize the name of the EBR service that will back it up. This name can be specified during installation of the EBR program, or it can be centrally assigned by the administrator. In addition, an administrator must add your workstation' s name to the EBR service's client list.
If this is the first time you are using EBR, it will prompt you to choose a name for your workstation. Workstation names are limited to 16 characters. Your system administrator may want to assign your workstation' s name, or you may be allowed to choose the name yourself. It is very important that you and your administrator agree upon a client name. Before you run the EBR program, however, the administrator must assign your workstation, by name, to the EBR service that will back it up. You must complete the information in the following dialog box:
1. Enter the name of your system into the Client Name field.
2. Click the OK button. EBR verifies that the name you have selected matches a name on the EBR service's client list. Once the name has been verified, the EBR Main window appears. From this window, you can initiate backups, recovers, archives, or you can verify files.
Administrators: Before a user can establish a unique client name, you must create that EBR client using the Clients command of EBR Administrator. Refer to the VINES EBR Administrator's Guide for details.
This section shows you how to back up and recover a file using EBR. Follow the instructions in this section to become familiar with the program. Chapter 3 has more detailed information on using EBR.
Depending on how your system administrator has set up the network, you may back up either:
Your workstation's disk drives only Any network drive, and your workstation's disk drives
To try out EBR, back up any file or directory on your local disk to the EBR server. In addition, you may recover files on your local disk. However, you cannot perform a scheduled back up on a network drive. When you back up a disk volume, directory, or file, an index is created on the EBR server for your system.The index contains entries for the files you back up. Later, you can browse this index to mark volumes, directories, or files for recovery.
Follow these steps to back up a file:
1. Click on the Backup speedbar button:
If you prefer, you may choose Backup from the Operation menu.
The EBR speedbar changes, and a Backup browse window appears. A browse window contains a graphical representation of your files and directories. It is similar to the Windows File Manager. If you are familiar with that program, your skills will help you navigate EBR browse windows.
2. In the left portion of the Backup window, click on the directory folder labeled "C:" , then select a file to back up - for example AUTOEXEC.BAT, by clicking on it.
Notice the slash (/) at the top of the directory tree in the left window pane. In EBR, slash represents root, or the very beginning of the file systems on your workstation, including all disk volumes with the directories and files they contain. Whenever you mark slash for a backup, you are selecting all hard disk drives on your system for the backup. Whenever you mark the C: or D: directory folder, you are selecting an entire disk volume for backup.
3. Click on the Mark speedbar button to mark selected files (in this case, AUTOEXEC.BAT) for backup.
If you prefer, you may choose Mark from the File menu.
A check mark (_) appears next to the directory or file you select. If you selected a directory, all its nested subdirectories and files are marked for recovery.
To unmark an item in the Backup window, click the Unmark button on the speedbar, or choose Unmark from the File menu.
Note: If you have a multi-button mouse, the secondary button (usually on the right) alternately marks and unmarks files.
4. Click on the Start speedbar button to initiate backup:
If you prefer, you may choose Start Backup from the File menu.
It will take a few moments to back up your file, depending on file size, network traffic, server load, and tape positioning. During this time, confirmation messages appear for each file backed up in the Backup Status window, so you can monitor the progress of your backup.
Note: If your backup takes a very long time with no new messages appearing in the status window, there may be no backup volume mounted on the server. Contact your system administrator for assistance. You may cancel the backup by choosing End Backup from the File menu, or by pressing [Esc].
After your backup is finished, the EBR speedbar returns to its initial state.
5. Close the Backup Status window, either by double-clicking on its control-menu box, or by choosing Close from the File menu.
Now that you have successfully backed up a file, you can learn the recover procedure.
Backing up Network Drives
You may back up files and directories on network drives if your system administrator permits you to do so. To back up a network drive, you must use the Change Selection command, described in Chapter 4. You may also use Change Selection to back up a floppy diskette.
Follow these steps to recover the file you just backed up:
1. Click on the Recover speedbar button:
If you prefer, you may choose Recover from the Operations menu.
The speedbar changes again, and a Recover window appears, similar to the Backup browse window.
2. Click on the directory folder labeled "C:" in the left portion of the Recover window. The backup index for your C: disk drive appears in the right portion of the window.
In the Recover window, look only at entries for your backed-up disk files on the EBR server's index, not the actual disk files currently on your system. Notice that backup times are listed to the right, and that files are organized exactly like the disk volumes, directories, and files on your system. This arrangement makes it easy for you to navigate.
The speedbar's Find button helps when searching large indexes. See Chapter 4 for details.
3. Select a file to recover, in this case AUTOEXEC.BAT, and mark it for recovery by clicking the Mark button on the speedbar.
If you prefer, you may choose Mark from the File menu.
A check mark (_) appears next to the directory or file you select. If you selected a directory, all its nested subdirectories and files are marked for recovery.
To unmark an item in the Recover window, click the Unmark button on the speedbar, or choose Unmark from the File menu.
Tip: If you have a multi-button mouse, the secondary button (usually on the right) alternately marks and unmarks files.
4. Click on the Start speedbar button to initiate recovery.
If you prefer, you may choose Start Recover from the File menu.
It will take a few moments to recover your file, depending on file size, network traffic, server load, and tape positioning. During this time, messages appear for each recovered file in the Recover Status window, so you can monitor the progress of your recovery.
Since you did not actually lose any data, the file you are recovering already exists on your local disk. EBR displays the Naming Conflict dialog box, allowing you to choose between renaming or discarding the recovered file, and overwriting the existing file.
5. Click the OK button. EBR renames the file.
6. EBR displays the Rename dialog box and suggests a new name. Accept the name by clicking the OK button.
The Naming Conflict window appears for each file you recover that already exists on your disk. To prevent the Naming Conflict dialog box from appearing for each file, check the Suppress Further Prompting option in the Naming Conflict window, after selecting the Conflict Resolution you prefer.
Tip: For instructions on placing recover files in a directory of their own, see Chapter 5.
Note: If the backup volume with your system' s files are still on the tape currently in the tape drive loaded in the EBR server, the recovery will proceed. If it is not, the EBR service notifies the administrator (but not the person who made the recover request) that a specific tape is required. Until that tape is mounted, your recover request will wait. You may cancel the recovery by choosing End Recover from the File menu, or by pressing [Esc].
When the recovery is complete, EBR displays messages in the Recover Status window:
You can look for your recovered files to confirm they were really recovered. To look at the files on your system, view them from either the DOS prompt, the Windows File Manager, or the EBR file browser described in upcoming chapters.
The Exit command is in the File menu of every window. Exit quits the EBR program and returns you to the previously active Windows program. To exit from EBR:
Choose Exit from the File pull-down menu. Tip: Or double-click on EBR's control menu box.
Banyan provides the Scheduled Backup program as part of EBR so that you can back up your files automatically on a pre-determined schedule. Use the Scheduled Backup icon in the EBR program group to start this backup program. If you or someone else installed this program into the Windows StartUp group, Scheduled Backup starts automatically when you start Windows. If it was not installed in your StartUp group and you want it to be, see the instructions in Chapter 3.
1. Inside the EBR program group, double-click on the Scheduled Backup icon:
EBR displays the Scheduled Backup program, with a Scheduled Backup Status window inside, containing this message:
Waiting to be contacted for backup by servername...
2. Leave your workstation powered on and running Windows so that the EBR server can back it up. (You can also turn off your monitor).
3. When you come to work in the morning, check this window for messages about your backup. You should see a message similar to this one:
Scheduled save started at 7-13-95 10:57p
clientname: C:\ level=incr 4354KB 00:02:27 13 files
You should check the backup status from time to time. See Chapter 4 for instructions.
Once Scheduled Backup is running, you do not need to take any action to make your system available for regularly scheduled backups. However, you may want to customize your system for scheduled backup, using the Local Directives command. See Chapter 3 for more details.
During the quick tour of EBR, you learned how to:
Use the Backup window to browse your system and prepare for backup Mark a file for backup, and start a backup Use the Recover window to browse index entries on the EBR server for your backed-up files Mark a file for a recovery, and start a recovery Resolve a naming conflict during a recovery Make your system available for scheduled backup
The quick tour is intended to familiarize you with EBR. Upcoming chapters provide more detailed information about EBR features.
