Good or bad idea?...offsite disk.

[Johnny Lea]

One of my TSM servers is using disk only for onsite pools and tape for offsite. 
 I am considering putting a SAN offsite to mirror my onsite diskpools thereby 
doing away with tape all together.  This server has about 12TB of storage.  I 
have a dedicated fiber link to my offsite location.
Is this a good or bad idea?  I understand that DRM won't be in effect any 
longer.  Client restores would be more readily available if needed but what 
about the database?  Any considerations or recommendations there or elsewhere?
 
Thanks,
Johnny
