To use DB2® Advanced Copy Services (ACS), or perform snapshot backup operations, you must install, activate, and configure DB2 ACS.
DB2 ACS is part of the IBM® DB2 High Availability (HA) Feature. To use DB2 ACS, you must have a license for the DB2 HA Feature.
After you have enabled DB2 ACS, you can perform snapshot backup operations.
For detailed instructions on the setup and usage of ACS, refer to the most recent Tivoli® documentation for Advanced Copy Services at: https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Tivoli%20Storage%20FlashCopy%20Manager
