Backup Medium (NetWorker) (SAP Library - External Backup Tools: SAP DB 7.2 and 7.3)

Backup Medium (NetWorker)

Use

If you want to perform backups or restores with the external backup tool NetWorker, you must define the appropriate backup media with the Database Manager.

Procedure

To create the backup medium, follow the procedure described in the Database Manger documentation.

Database Manager GUI: SAP DB 7.3, Section Backup ® Managing the Backup Media

Database Manager CLI: SAP DB 7.3, Section Calling the Database Manager CLI ® DBM Server Command ® Backing Up and Recovering Database Instances ® Commands for Backup Media

The media name must begin with the character string NSR.

Example

Definition of a pipe as a medium for an incremental data backup with a DBMCLI command (Windows NT):

dbmcli -d <database_name> -u <userid>,<password> medium_put NSR123 \\.\pipe\Example pipe pages

The backup medium must be a pipe and must not have any capacity limits.

The name of the pipe must be specified as an absolute path. The pipes used must not exist.

Windows NT: Pipe names must be in the following form: \\.\pipe\<pipe_name>

UNIX: There are no particular naming conventions to follow for pipe names.

The absolute name of the pipe must be identical at backups and restores. Note that file or directory paths that are specified as links are resolved by the backup tool NetWorker.

Example

On Server A, a backup is performed using /tmp/nsr_pipe. The directory /tmp is a link to the directory /var/tmp. When restoring to Server B, you must use the pipe var/tmp/nsr_pipe.

You can perform parallel backups using multiple pipes.
