Introduction

This appendix contains the procedures for performing a backup of the database to the FTP server and to restore a database from the FTP server using the chg-db command.

To backup the database, the chg-db command uses these parameters.

• action=backup - perform a backup of the database.
• dest=server - the destination of the backup operation, the FTP server.

To restore the database, the chg-db command uses these parameters.

• action=restore - restore a previously backed up database.
• src=server - the source of the database that is being restored, the FTP server.
• file - the name of the TAR file on the DB FTP server that contains database that is being restored.

A removable cartridge is not required and cannot be used to backup the database to the FTP server or to restore a database from the FTP server.

To perform a backup of the database to the FTP server or to restore the database from the FTP server, these items must be provisioned in the database.

• An E5-IPSM - perform the procedure Adding an E5-IPSM.

  Note:

  As of Release 46.5, the E5-IPSM card and its functionality is replaced by the E5-ENET-B (p/n 870-2971-01) or SLIC (p/n 7094646) card. Any references to E5-IPSM and the 870-2877-01 part number should be replaced by the 46.5 and greater card and part number.
• An FTP server for the DB application - perform the procedure Adding an FTP Server.

When the database is backed up to the FTP server, the database on the active partition of the active TDM is packed and compressed into a TAR file andsends the file to the FTP server through an E5-IPSM. Figure D-1 illustrates this action.

Figure D-1 Backup of the Database to the FTP Server

When the database is restored from the FTP server, the TAR that contains the database that is being restored is retrieved by EAGLE through an E5-IPSM. The TAR file is unpacked and uncompressed and the database files are placed on the active partition of both TDMs. Figure D-2 illustrates this action. The EAGLE must be reinitialized to load the restored database to all the cards.

Figure D-2 Restoring the Database from the FTP Server

To perform a backup of the database to the FTP server, perform the procedure Making a Backup of the Database to the FTP Server.

To restore the database from the FTP server, perform the procedure Restoring the Database from the FTP Server.
