Backup Environment

While you can run a backup for a network environment where there is only a single Cisco Vision Dynamic Signage Director server, the recommended environment that is described in this document is a redundant environment for either Platform 2 or Platform 3 servers or a virtualized environment. In a redundant environment, you are running Cisco Vision Dynamic Signage Director on a primary server, with a secondary server connected to the same subnet where the backup data from the primary server is saved.

The backup process can be scheduled and also run manually. When a backup is completed, the CMS is automatically restarted.

In Cisco StadiumVision Director Release 4.1 and later releases, the backup task can run even while an event script is running. As part of this change, the database is no longer optimized or repaired during the backup process—a new TUI option is added to run database maintenance manually if needed.

Although it is not expected that database maintenance should be needed on a regular basis, a possible symptom could be slow performance indicating a need to run database maintenance.

Tip: You can look at the backup log (/var/log/svd-config/backup-YYYMMddHHMMSSz.log) to see if the table updates are “OK” and up-to-date. If not, then use the TUI option to run database maintenance. For more information, see the “Running Database Maintenance” topic in the Cisco StadiumVision Director Operations Guide.

What Cisco Vision Dynamic Signage Director Data is Backed Up

There are several areas of Cisco Vision Dynamic Signage Director that need to be backed up. The backup process backs up the following areas of the Cisco Vision Dynamic Signage Director server:

■Uploaded fonts

■Cisco Vision Dynamic Signage Director Content Management System (CMS)

■Cisco Vision Dynamic Signage Director database

■Cisco Vision Dynamic Signage Director system configuration files

■Content Integration data

■Dynamic Menu Board data (including GAR files)

■Proof of play report data in the /var/sv/pofp/data directory

Caution: The proof of play raw data in the /var/sv/pofp/raw directory is not backed up.

Disk Storage and Maintenance

Note: To be sure that your system has enough disk space, Release 4.0 and later releases only retain one backup file by default.

For more information, see the “Managing Server Resources in Cisco StadiumVision Director” module of the Cisco StadiumVision Director Operations Guide.

Restore Environment

As with backups, you can schedule the restore process or run it manually. When the manual restore screen is displayed, it lists backups from both the backup and restore directories, concatenated together. This allows you to run a manual restore on either the primary or the secondary server. An automated restore always uses the most recent backup file in the restore directory.

Also, the schedule of tasks to run in the primary database and the secondary database will be different, due to the existence of the backup and restore tasks. Therefore, the schedule itself is not automatically restored.

Enabling the Backup Account on the Secondary Server

Before you set up the primary Cisco Vision Dynamic Signage Director server for automatic backup and restore with a redundant secondary server, you need to enable the backup account on the secondary server using the TUI.

For more information about using the TUI, see Cisco Vision Dynamic Signage Director Server Text Utility Interface.

To enable the backup account on the secondary server, complete the following steps:

1. On the secondary server, log into the TUI by doing the following:

a. Use a directly connected console, or use an SSH client from a laptop computer that is connected to the Cisco Vision Dynamic Signage Director server network to run a secure login to the secondary Cisco Vision Dynamic Signage Director server using the IP address for your server.

b. When the login prompt appears, enter the installer userid followed by the installer password at the password prompt.

2. From the Main Menu, go to the System Accounts > Enable/Disable Backup User menu (Figure 1).

Figure 1 Enable/Disable Backup User Menu

1. Select Enable backup user account.

Tip: To navigate through the TUI menus you must type the character that corresponds to the menu area where you want to go (a, b, c, and so on) and press Enter. To return to other menus, you must back out of the hierarchy of menus using one of the indicated keys to return you to prior menus.

When successfully created, the following messages are displayed:

2. Press any key to return to the Enable/Disable Backup user menu.

3. Continue to return to the Main Menu and exit the TUI.

Setting Up the Primary Server for Automatic Backup and Restore

The configuration of the backup accounts and directories between the primary and backup server is automated using a TUI menu option. You need to use the TUI to setup the Cisco Vision Dynamic Signage Director Server environment to be able to run the backup and restore processes.

Note: The TUI is only used to configure the backup environment. You need to use the Management Dashboard to schedule or run any manual backups. For more information, see Scheduling a Regular Backup and Starting a Backup Manually for Immediate Execution.

To set up the primary server for automatic backup and restore, complete the following steps:

1. On the primary server, log into the TUI by doing the following:

a. Use a directly connected console, or use an SSH client from a laptop computer that is connected to the Cisco Vision Dynamic Signage Director Server network to run a secure login to the primary Cisco Vision Dynamic Signage Director server using the IP address for your server.

b. When the login prompt appears, enter the installer userid followed by the installer password at the password prompt.

2. From the Main Menu, go to Cisco Vision Server Administration > Setup automatic backup and restore.

Figure 2 Setup Automatic Backup and Restore Menu Option

3. At the prompt type the IP address or hostname of your secondary server as shown in the example in Figure 3:

Figure 3 Secondary Server IP Address Configuration

4. At the prompt, type the password for the installer account on the secondary backup server.

5. When accepted, the system generates the RSA keys and the public key is copied to the secondary server. Confirm that the keys are created without errors as shown in (Figure 4):

Figure 4 Generation of RSA Keys

6. Wait until the “Press any key” message appears (there can be a short delay before it is displayed).

7. Then, press any key to return to the Cisco Vision Server Administration menu.

8. Continue to return to the Main Menu and exit the TUI.

Scheduling a Regular Backup

After you have configured the servers to support the backup process, you need to schedule backups using the Management Dashboard in the Cisco Vision Dynamic Signage Director software.

To configure a backup to run on a regular schedule, complete the following steps:

1. Log into the primary Cisco Vision Dynamic Signage Director server as an administrator.

2. From the Cisco Vision Dynamic Signage Director main menu, click Management Dashboard.

The Cisco Vision Dynamic Signage Director Management Dashboard opens in a new window.

3. Select Tools > Advanced > Scheduled Tasks.

4. Click Add Row and scroll to the new blank line.

5. Click in the Task Type column and type BackupTask (Figure 5).

Note: Be sure to type the name of the task exactly as shown with upper and lowercase characters.

Figure 5 Adding a Backup Task to Run on a Regular Schedule

6. Click in the Task Time column and specify the time (in 24:00 format) when you want the backup to run.

7. Click in the Servers column and type config.

8. Click Apply.

Starting a Backup Manually for Immediate Execution

If you want to start a backup other than at the regularly scheduled time, you can run a backup manually.

To start a backup manually for immediate execution, complete the following steps:

1. Log into Cisco Vision Dynamic Signage Director as an administrator.

2. From the Cisco Vision Dynamic Signage Director main menu, click Management Dashboard.

The Cisco Vision Dynamic Signage Director Management Dashboard is opened in a new window.

3. Select Tools > Advanced > Run a Task.

4. In the Tasks to Run box, select the BackupTask ( Figure 6).

Figure 6 Running a Scheduled Backup Task Manually

5. Click Apply.

The backup begins immediately. When completed, the CMS is automatically restarted.

Note: The “success” message that appears means that the backup task has started. It does not mean that the backup has completed.

Verifying Backup Completion

To verify backup completion, you should confirm that a backup file exists and also that no errors appear in the log file.

Verifying That a Backup File Exists

Note: Verifying the existence of a backup file only tells you that a backup was attempted, but not necessarily if there were any errors.

To verify that a backup file exists, complete the following tasks:

1. Log into Cisco Vision Dynamic Signage Director as an administrator.

2. From the Cisco Vision Dynamic Signage Director main menu, click Management Dashboard.

The Cisco Vision Dynamic Signage Director Management Dashboard is opened in a new window.

3. Select Tools > Advanced > Restore system data from backup.

4. Verify that backup files with dates and times appear.

Finding Backup Errors in the Log File

Note: Be aware that the messages “Starting backup” and “Backup completed” will always appear in the log regardless of success.

To find backup errors in the log file, complete the following steps:

1. Open the /opt/sv/servers/config/logs/sv_dev_debug.log file.

Tip: You can access log files from the TUI, or by running a System State Report from the Cisco Vision Dynamic Signage Director main menu.

2. In the sv_dev_debug.log file, find messages that include the string “com.cisco.sv.backup.”

These are the backup process messages.

3. Find the “Starting backup” message.

4. After the “Starting backup” message (but before the “Backup completed” message), look for a “com.cisco.sv.backup” message that also includes “ERROR” in the string.

If you find this error, the backup did not complete successfully.

Modifying the Number of Backup Files to Retain

To reduce the amount of disk storage required in your system, the default backup retention policy is to keep one backup file. This retention policy can be modified to retain 2, 5, 7, or 10 backup files.

Caution: Be aware of your overall disk utilization and the size of your backup content to be sure that the number of backup files that you want to keep can be supported by your system resources.

Note: This task must be run on both the primary server and secondary backup server.

To modify the number of backup files to retain, complete the following steps:

1. Log into the TUI by doing the following:

a. Use a directly connected console, or use an SSH client from a laptop computer that is connected to the Cisco Vision Dynamic Signage Director server network to run a secure login to the primary Cisco Vision Dynamic Signage Directorserver using the IP address for your server.

b. When the login prompt appears, enter the installer userid followed by the installer password at the password prompt.

2. From the Main Menu, go to Cisco Vision Server Administration > Retention Policy > Backup/restore Files.

A menu of policy options is displayed (Figure 7), where you can choose to retain 1 (the default), 2, 5, 7, or 10 backup files.

Figure 7 Backup Retention Policy Menu

3. Type the letter that corresponds to the number of days that you want to retain files and press Enter.

4. When the change of policy confirmation message displays, press any key to return to the Cisco Vision Server Administration menu.

Figure 8 Confirmation of Policy Change

5. Continue to return to the Main Menu and exit the TUI.

Starting a Restore Manually for Immediate Execution

If you want to start a restore other than at the regularly scheduled time, the Cisco Vision Dynamic Signage Director software also allows you to run a restore from backup to begin immediately.

Caution: You cannot successfully run the restore process while an event script is running. In addition, if your venue was running any script when the backup took place, then those scripts will begin running after the restore.

To start a restore manually for immediate execution, complete the following steps:

1. Log into Cisco Vision Dynamic Signage Director as an administrator.

2. From the Cisco Vision Dynamic Signage Director main menu, click Management Dashboard.

The Cisco Vision Dynamic Signage Director Management Dashboard is opened in a new window.

3. Select Tools > Advanced > Restore system data from backup.

4. For Components, select All components except Scheduled tasks (Figure 9).

Figure 9 Running a Restore Task Manually

5. (Optional) If you do not want to restore the latest backup (the default), then in the System backup time box, select the date and time of the backup file that you want to restore (Figure 9).

6. Click Apply.

The restore begins immediately.

Note: If you need to also restore the scheduled tasks, you can rerun the Restore system data from backup and for Components, select Scheduled Tasks.

Restarting the Cisco Vision Dynamic Signage Director Software

After you perform any restore on a Cisco Vision Dynamic Signage Director server, you must restart the Cisco Vision Dynamic Signage Director software to resume normal operation of the services.

To restart the Cisco Vision Dynamic Signage Director software, complete the following steps:

1. On the primary server, log into the TUI by doing the following:

a. Use a directly connected console, or use an SSH client from a laptop computer that is connected to the Cisco Vision Dynamic Signage Director server network to run a secure login to the primary Cisco Vision Dynamic Signage Director server using the IP address for your server.

b. When the login prompt appears, enter the installer userid followed by the installer password at the password prompt.

2. From the Main Menu, go to Cisco Vision Server Administration > Restart Cisco Vision Dynamic Signage Director Software.

3. Return to the Main Menu and exit the TUI.
