[Veritas-bu] NBDB backup scripts?
2001-01-24 20:38:22
No, it works. I just have trouble with all the things AROUND bysyncinfo:
1. Finding/getting an UNUSED tape in the NetBackup pool.
2. Protecting the tapes that used to be the NDBD backup tapes from being
overwritten.
Here's the script that I am currently using. I've taken some of the error
checking and functions out for brevity. I think it's working in its
current form. I'm open to suggestions.

# pool and in the robot that we are using #
