Yeah.... that must be an error in the RedBook. I just checked and there
is an updated (02) version called z/OS Distributed File Service zSeries
File System z/OS V1R7 Implementation, but it says the same thing:
"You can back up zFS file systems by doing the following:
A zFS aggregate can be backed up and restored using IDCAMS REPRO.
The aggregate must be quiesced before the backup.
A zFS aggregate can be backed up and restored using DFSMSdss.
The aggregate must be quiesced before the backup."
Even if REPRO worked, you would have to unmount the zFS, not just
quiesce it since OMVS owns the data set and has an exclusive ENQ.
