DFDSS will not dump an offline volume. So, IMO, online to the host does matter if the intent is to use DFDSS for the backup.
However, this doesn't affect, in any way, the validity of your points about the guest, buffers, multi-volume files, etc. In our case, it was determined that we did not need to be concerned about these questions as these backups are for system recovery only. Application files have their own backups (I believe they're using Netbackup). ddk >In the recent past, we were using ADRDSSU to create backups of our >zVM/Linnux volumes for our DR, but it required that we vary the volumes >online.

How do you ensure that all buffers are synched? Is there any risk to multi-volume files? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
