>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?

  Job

  what is "snapshot technology" ??
