Did you mean from the command line?
You can restore the IDB from the command line in this manner:
omnir -omnidb [object ID] -session [session_id] -tree [path to IDB] -into [destination directory]
for example:
To restore an IDB on the client "server" and pathname "/usr/omni/config" from data created
in the backup session "2011/07/24-2", run:
omnir -omnidb server:/ -session 2011/07/24-2 -tree / -into /tmp/omnidb
When using the CLI method, entering the session ID of the backup is required
