Does file archiving require content- or CAS-based storage?  It
depends on why you're archiving your data. If you're archiving
for compliance, it's critical to understand the specific
regulations      Requires Free Membership to View  or policies
you are obligated to uphold. Some compliance regulations
indicate that you have to preserve and protect the data in an
unchanging/unalterable state. That might require storage on a
WORM device or a disk-based content-addressed storage (CAS)
system with access controls that prevent file changes using
authentication and preservation checksums. Some storage
solutions tout this approach as the "preferred" archiving
technique, but that's not necessary in every situation. For
general-purpose file archiving without regard to compliance
regulations, an ordinary disk or tape system would probably be
adequate.  Go back to the beginning of the File Archiving FAQ
