name

Can be 1) logical pathname of the backup object, 2) user ID, 3) message store mailbox name. Backup objects and paths: 

• Entire message store: /

• Message store partition: /partition_name (default: /primary)

• Backup group—a group of users defined with regular expressions in a configuration file. See To Create Backup Groups in Sun Java System Messaging Server 6.3 Administration Guide for details. Path: /partition_name/backup_group(/primary/user represents all users under primary).

• User: /partition_name/backup_group/user_ID

• Mailbox:/partition_name/backup_group/user_ID/mailbox_name

• Message:/partition_name/backup_group/user_ID/mailbox_name/msgID

User IDs: can be any user ID in the message store. If the user is not in the default domain, the user ID must be fully qualified (example: Wally@siroe.com). If user is in the default domain, the user ID can stand alone (example: Wally).

mailbox: An email folder. It is specified using the following message store internal name:

user/user_ID/folder_name.

Note that user is a message store keyword.
