Re: Question on Tape Density, etc...

[Chuck Lewis <CLEWIS@xxxxxxxxxx>]

That I HAD figured out back in the 3490 - 3590 days. :-)

Our Nightly backup went from 88 minutes to 36 minutes last night !!! This was
TOTALLY a result of reinitializing the tape as a 5GB instead of a 2GB - UNREAL
!!!!!

Thanks AGAIN,

Neil
