Re: [Networker] Backing up Large File Systems

Kathleen-
I was recently in the EMC Avamar admin class gave some recommendations:
1TB files systems
<10 Millions files
<2TB databases

I would approach the vendor or applications people and explain some of the
inherent limitations in backing up file systems that are too large or have
too many files.
