I've been backing up to disk for a while.  The disk storage unit shares the
single master/media server that services my entire environment.  You don't
need a special media server for this purpose but the media server has to
have access to the disk, DAS, SAN, NAS or similar.

I use to for the frequent small backups that I do for my Oracle archived
redo logs.  I have a script that wakes every four hours to duplicate the
images from disk to tape, then expires the disk copy.  This aggregates my
small backups & minimizes tape movement & delay.

The only problem I've had is that tape drives compress automatically while
disks do not.  Client-side compression isn't that good & loads the CPU too
much to use.  The images on disk, therefore, are full-sized.

Subject: [Veritas-bu] Looking to backup data to Disk vs. Tape


Environment-W2K Media/Master Server backing up about 500GB per night.

Does anyone have suggestions or comments about backing up data to disk?  

Would I need a media server allocated just for disk backups? 

Would this media server have to be directly attached to this disk device?

What are some problems users have experienced with disk backup?
