System Restore

The following feature is only available at the System or Product Administrator level. SO and Customer or Site level accounts cannot access this feature.

Restoring the database allows you to replace the database on the MSP N-central server with a backup in the event of a failure or data loss. After the database has been backed up, the date, file size, and the backup downloadable files are listed on the Restore Backups screen.

The backup files include a backup file and a backup digest file. The backup file contains all of the information needed to restore the database. The backup digest file contains the checksum needed to verify whether or not the backup file has been corrupted.

When you restore the database, you can also indicate whether or not you would like to restore the historical data or network information. The historical data includes statistics on device statuses and system events while the network information includes data on the DHCP, hostname, IP address, netmask, default gateway, primary and secondary DNS, and mail relay server.

When restoring the database, the time zone configuration of the target server must be the same as the source server.

Restore the database using a backup file

  1. Reinstall the same version of MSP N-central that was installed before the failure.
  2. In the navigation pane, click Administration > System Backup and Restore > Restore Backup.
  3. In the Restore Backup screen, configure the following properties:
  4. Backup Details

    Restore Method

    Select the type of database restoration from one of the following options:

    • From Local System - which allows you to restore the database using the backup files stored on the MSP N-central server.
    • From My Computer - allows you to restore the database using the backup files that you have downloaded to your computer.
    • From FTP Server - which allows you to restore the database using the backup files that you have saved on an FTP server.

     

    If you selected From Local System, select the Backup File Name (ncbackup file in .TGZ format) that you would like to use to restore the database.

    If you selected From My Computer:

    1. Type the Backup File Name (including the directory path and name of the backup file in .TGZ format) or click Browse to navigate to the file.
    2. Type the Digest File Name (including the directory path and name of the backup digest File in .SHA1 format) or click Browse to navigate to the file.
    3. If required, click Check Digest Values.

    The Current Backup File, Current Backup File's Digest Value, Current Backup Digest File, and Current Backup Digest File's Value are displayed.

    The digest values are generated at the time of the backup. If the backup files have been modified, the digest values will not match and an error message will be displayed to indicate that the backup files may be corrupted.

    The maximum upload size is 2Gb. For larger backups, use the FTP method.

    If you selected From FTP Server:

    1. Type the Server Address (in the form of an FQDN or IP address) of the FTP server.
    2. Type the Username of the FTP server account.
    3. Type the Password of the FTP server account.
    4. Type the Directory on the FTP server in which the backup files are stored.
    5. Type the Backup File Name of the backup file (*.tgz).
    6. Type the Digest Filename of the backup digest file (*.sha1).

    Disable All Outbound Communication

    Select this option to suspend outbound communication from the MSP N-central server.

    If this option is selected, it will prevent all PSA tickets, notifications, warranty requests, and other messages from being transmitted by the MSP N-central server.

    Include Historical Data

    Select this option to include the historical data in the restoration. This is the bulk of the data used for reports. Do not select this option if you are only restoring the configuration.

    Include Software And Script Repository Data.

    Select this option to include the software and script repository data in the restoration.

    You can restore the software and script repositories only if you have backed them up first.

    Include Network Information

    Select this option to restore the DHCP, hostname, IP address, netmask, default gateway, primary and secondary DNS, and the mail relay server name.
