Like any database, you should periodically back up the RASD to prevent data loss in the event of a device failure.
Sybase recommends that you always back up the RASD after you truncate
the primary database log.
The Replication Agent places RASD backup files in the directory identified by the rasd_backup_dir configuration parameter. See the Sybase Replication Agent Reference Manual for more information about the rasd_backup_dir parameter.
You need not interrupt replication to back up the RASD. You can back up the RASD at any time, when the Replication Agent instance is in any state.
To back up the RASD
Log in to the Replication Agent instance with the administrator login.
Use the following command to back up the RASD:
rasd_backup
After the backup completes successfully, the Replication Agent returns a message to confirm that the RASD backup was successful.
If the Replication Agent could not find the directory identified in the rasd_backup_dir parameter, or if it could not write the RASD backup files in that directory (for example, because of a permission problem), it returns an error. You must correct the cause of the error to successfully back up the RASD.
