About multiplexing
Multiplexed media contain interleaved data of multiple objects. Such media may arise from
backup sessions with a device concurrency of more than 1. Multiplexed media may compromise
the privacy of backups and require more time for restore.
Using the Data Protector object copy functionality, you can demultiplex media. Objects from a
multiplexed medium are copied to several media. Data Protector however reads the source
medium only once. To enable demultiplexing of all objects on the medium, the minimum number
of destination devices needed for the operation is the same as the device concurrency that was
used for writing the objects. If fewer devices are available, some objects will still be multiplexed
on the target medium.
