>what is "snapshot technology" ??
try google.. it's an old paper, but definition of snapshot still applies.
http://www.oracle.com/technology/deploy/availability/pdf/oscp_snapshot_use
.pdf
Introduction
With the constant increase for corporations and organizations to store
high volume amount of data,
and the need for implementing high available systems (HA) with minimum
down time for
maintenance, storage system vendors have developed and implemented new
technologies to fulfill
this requirement. One such technology is snapshot storage systems. Storage
snapshot
technology may allow Oracle customers to quickly backup and restore large
amounts of data
without jeopardizing data integrity nor performance of the online service.
---
The difference being that Oracle RMAN now has technologies like block
change tracking, guaranteed recovery points (utilizing flashback
technology), etc.. that may make snapshot technology less applicable to your
environment/needs.
Can RMAN with change block tracking meet your backup window requirement?
Can you effectively use RMAN to clone your environment? how fast do you
need to be able to clone?
