Where to enter the dump command

You can enter the dump command through a Remote Shell connection, such as through the rsh command, through a Telnet session accessing the storage system console, or through the storage system console directly.

Note: Other than potential problems associated with any remote connection, console access through a Telnet session and direct console connection to the storage system behave the same way.

Benefits of entering the dump command through a Remote Shell connection

Entering the dump command through a Remote Shell connection gives you these benefits:

  • When the dump command is in progress, you can still use the console to manage the storage system.

    If the dump command entered on the console is backing up a large number of files, you cannot use the console for a long time.

  • You can start multiple dump commands using the rsh command.
  • Data ONTAP is less likely to inadvertently terminate the dump command, especially if it is run in the background from a Solaris system.

    If you enter a dump command on the storage system console, it could be terminated by pressing Ctrl-C entered on a host connected to the storage system using a Telnet session.

  • You can automate storage system backups through shell scripts and crontab entries.

Benefits of entering the dump command at the console

If you enter the dump command at the console, you can read and respond to screen messages and prompts displayed by the command. For example, the command might prompt you for another tape to complete the backup, whereas a dump command entered through a Remote Shell connection does not generate any messages when the command needs user intervention, and terminates instead.
