Re: [Veritas-bu] LTO tapes handling more that it supposed

Dear Justin, sounds make sense for the hardware compression. but, I never set the hardware compression on the NBU. Did the compression do it self without any configuration triggered? I mean, is it running automatically for few types of files or datas?
And this is happening not to all tapes.. only few tapes.. some is oracle database, and some is windows flatfile.
@Simon: hopefully not David Copperfield who make strange thing happens on my backup.. :)
@everyone: So this is normal if it's a database backup? (specially oracle). just trying to describe all the inputs.. :)
Rgrds, Martin

The tape drive does compression. We see upwards of 3.0++ to 1 in some
cases.
