Script Help

[Nobody's Hero]

Ok, Still dealing with this dat auto loader issue. I was told to go to this link and use this script in conjunction with my fbackup -y command. I still am not sure how I do this. Do I start the fbackup command on 1st line and then append this script? Can someone please advise?

Hi Robert:

A key element is to declare the script (by name) in 'fbackup's configuration file (which you should have anyway to provide adequate 'fbackup' performance).

Have a look at the man pages for 'fbackup'. In the configuration file ('-c) is an optional entry "chgvol". The value of this argument is the name of the executable script.

Regards!

This needs to run as a seperate process. So start your fbackup, then launch this script.
