Re: [Veritas-bu] NBU catalog backups hot vs cold

Incidentally, I was on a Netbackup 6.5 course last week, the instructor
mentioned that cold backups will no longer be available in NB 7.0

Thanks guys. Some good responses there and yes i can now see why its a 
good idea and extremely useful for people who don't have down time.

My systems are not large enough for me to hit that problem thankfully 
and so it hasn't been a requirement of mine as yet.

I think what i am best doing is enabling hot backups but to run during 
the day when i can assume most of the jobs have finished. If a job is 
still running the information for that will be backed up on the next 
catalogue hot backup, which while will leave me exposed should 
everything hit the fan before this second hot backup has ran, will still

leave me with the majority of good images.

Cheers
