Remember... on Skytap you can mount a bootable/IPLable ISO with the SAVSYS. You need to use the Skytap media repository.

If you are uploading you data for DR purposes perhaps is a matter of creating a restore strategy. Maybe create a starting point with your Opt21 and then upload differential backups. Uploading 650GB is possible, but requires enough bandwidth , processing power and a nice script to restore smoothly.

Here we need to send a full system save (virtual tape in image catalog volumes) to a cloud provider (SkyTap) because they don't support physical tape.

The SavSys21 is about 650GB.  It is broken up into segments/catalog:

SAVSEC
SAVCFG
SAVIBM
SAVALL
SAVDLO
SAVIFS

Each image catalog is broken up into 25BGB volumes.

Sigh.

If files are big enough: Have you tried splitting in parts and using simultaneous uploads/downloads?

Hi Jerry,

DNS is not the same as Routes, but yes, adding a host entry and using *LOCAL on DNS configuration (check there’s no dead DNS entry) can help too.

Probably meaning to add entries to IBM I host table and specify *LOCAL for DNS lookup.

When connecting from IBM I you can add static routes to your target servers and avoid network broadcasting.

May I kindly ask for more details on this statement(s)?
