Improve AOT backup performance

See this idea on ideas.ibm.com

We're using IDAA loader V 2.1 to run backups for very huge AOTs. When IDAA loader takes a backup from an IDAA AOT it uses SQL multirow fetch to transfer the data from IDAA into a z/OS sequential file. This may work fine for small AOTs. But in our environment the AOTs are very big and the SQL fetch mechanism to backup the data is not a good choice since this leads to very high CPU usage and very long elapse times. For example we determine a 70 time longer elapse time, 35 time higher CPU usage, 2.8 time higher I/O-Count and 46 time higher SU count (including zIIP-SU for the IDAA loader Backup Utility) compared to a full DSNUTILB IC for a table containing the same data in Db2 for z/OS and on IDAA. (51'239'384'238 Rows)

From a product like the IDAA loader we expect a much better backup performance. There should be another mechanism than SQL fetch to transfer the data from IDAA to z/OS. For example DSNUTILB uses direct access paths to the VSAM Cluster to read the data instead of fetching it.
