My company has a single Exhange 2k3 server running on Windows 2003 Enterprise Edition. Our information store is 43GB. Right now we back everything up to tape. I'm wondering if it would be better to backup our exchange server up to disk during the day then backup the disk to tape at night. What are everyone thoughts on this? I know going B2D is not bound by hardware in the event your backup server or tape drive failed.
