Kenneth also picked up on an important point. With a VTL you can use
multiple devices for parallel saves, it speeds up the save to almost the
speed of the communications link. A really good thing. There is a BUT.
In a recovery you must have at least the same number of devices used to save
with. While it's possible to recover from fewer, it's painstaking and
tedious, and massively slow, almost to the point of not worth the effort.

Is anyone using a "tapeless" backup process that FULLY integrates with
BRMS?
Yes, we use an IBM ProtecTIER Gateway VTL. It emulates an LTO3 tape drives
tape library, and deduplicates and writes the data to an external storage
disk system. It also provides tapes IP replication to another VTL for DRP
purposes.
In other words, one that just "presents" a virtual tape library to the
system and allows BRMS to manage everything, such as parallel BU, tape
volume initialization, D-IPL capability etc...
Full functionnality as you expect. We intensively use parallel backup, as
the VTL limits the throuput to an LTO3 drive's one, and duplication to
physical tapes.
