There is no such version as 7.11
The only way I can see to do this is to have a script that checks for the existance of this file. If the file is found, in the script, run
/opt/omni/bin/omnib -datalist [Backup Specification Name] Do not include the [ ] marks
I am assuming that you are talking about having the file arrive on teh client system. You would need to have the User Interface component so that you actually runthe command to start the backup from that server. You would also probably need to have a line in the UserList file that contains a user with 'root' permissions for that server
