The Auxiliary (DASH) copy is almost double to its primary copy.
The data size of jobs under primary copy are almost double when compared to jobs under primary copy.
Both Primary and Secondary copies were stored in different media agents.
In Aux copy, under General Properties 'Space Optimized Auxcopy' option is enabled too.
Retention period of aux copies is identical to its primary copies.
Even Tried sealing the DDBs and still of no improvement.
The block size is same for the two Global DDBs (Primary copy and secondary copy - 128kb)
Any ideas or suggestions would be helpful.
