For what it's worth we have a customer saving to virtual tape each night (actually backup goes directly to LTO-5 tape first because it's faster, and tape on a different controller to the disk, then the DUPTAP to virtual tape) then they FTP the virtual tape file to another system (Intranet, gigabit Ethernet, a couple of hundred meters away) and restore that to the backup box.
Last night the FTP job sent over 265,279,025,313 bytes.
It took 8 hrs 52 min 23 sec.

Subject: Re: replicate PROD iseries box to distant TEST box cross-country
Years ago, we created a "simple" CL and ran this type of sav/rst from PDM. Worked quite well.
But our systems were in the same room and 30 GB was not even on our radar.
Since it doesn't sound like the restore is time sensitive, I would just try it and if the 30GB aren't transferred within a day or two, then explore alternative. Obviously, you could trial this if the line is already in place. Just create a save file that is one GB and pass it over - multiply by 30 and add a few days for restart issues.

I thought we could do SAVE while active to Save files!!
Saves to a save file are limited to one /library/ object. Thus
"saving to save files won't allow" saving "more than one" library. And
that is irrespective the Save active (SAVACT) specification on the save
command.
Also, doesn't the SAVRSTOBJ needs SNA setup?
Yes.

_i ObjectConnect function i_
"...
To use the ObjectConnect functions, you must have ObjectConnect
installed on both the source and target systems. The systems must be
connected with one of the following methods:
* Local area network (LAN) or remote communications line with
Advanced Program-to-Program Communication (APPC) and Advanced
Peer-to-Peer Networking (APPN*).
* LAN or remote communications line with Transmission Control
Protocol/Internet Protocol (TCP/IP) with AnyNet* or Enterprise Extender
support.
* Fiber optic bus with OptiConnect.

Enterprise Extender [or AnyNet] would enable that capability over TCP/IP.

_Configuring Enterprise Extender communications for the iSeries system_
"Enterprise Extender is a networking architecture that allows Systems
Network Architecture (SNA) applications to run over IP networks using
High Performance Routing (HPR).
Enterprise Extender is the preferred way to run SNA applications over IP
networks with communications input/output adapters (IOAs), such as
Gigabit Ethernet, because these IOAs do not require an input/output
processor (IOP). Communications adapters that do not use an IOP do not
support SNA. Therefore, Enterprise Extender is required to run SNA over
these adapters. It is recommends that Enterprise Extender be used in
place of AnyNet®.

If more than one, do the objects and data need to be in synch in the
saved libraries ? If they need to be in synch, are you stopping any
processes that might cause updates while the save takes place ? This
is where a save to virtual tape might prove more effective as you
can use save while qctive to minimise the outage window and also save
all the libraries in <one> hit. Saving to save files won't allow you
to do that.
If it's only one library and the machine is another IBM i I would
skip the FTP option and go with SAVRSTOBJ in most cases. It uses
less storage and is much tidier, in my opinion.
