RE: Restoring to another system using an image catalog

Just to clarify,
I was planning on getting the new partition up to the point of having TCP running.
We will assume the customer has the disk space to create a backup using virtual tape.

The following are the high level steps I am fuzzy on - whether to save the image catalog or use save files?

Have the customer do a system save to the virtual tape.
Load it to an image catalog
Send the image catalog to the new system via FTP
Restore the image catalog
Do the system restores from virtual tape on the new partition.


Thanks,
Sherry

So with remote sites the virtual optical back to the host site is not so likely to be the best bet unless you have a very solid high speed (especially low latency) pipe. The network based virtual optical stuff works over NFS and that doesn't appreciate high latency environments.
Then if you think about it you have to move the entire contents of the partition anyway so perhaps simply moving it first is a better plan although it does use up disk space on both sides. (WHICH I am OK with because I sell disk. :-) )

So to copy the images would require you get the new partition up to the point of having TCP/IP running in order to FTP in the images. That may work for you or not, your call.

I know you guys have 'more than one' system so perhaps the images could be FTP'd to another system at the DR site and then accessed there. Which is faster FTP or sending tape depends on the speed of the connection between sites and the size of the systems.

Another different course is something such as a Crossroads SPHiNX at each site, you back up to the local one, it replicates the virtual tape to the remote site, and you restore from the remote tape. The SPHiNX appears to be an LTO drive to the system so you're using standard IBM Save/Restore commands but the tapes are virtual.

If these partitions are in the same room this "FTP" thing is so last decade! What you really want is a network based virtual optical drive.
With that you leave the image catalog on the system where you saved it and restore directly to the new system.

Many varieties of configuration exist for your server of course. Can you describe a little better your host and client partitions including IBM i versions?

Does anyone have a high level checklist of how to do a system save on one partition, save to an image catalog, ftp the image catalog to another system and then restore from the image catalog? I am looking for 2 different scenarios. The first is: I have just a minimal partition built and want to replicate the host system to the new partition and the second option is the partition is up and running and I just need to restore all of the libraries. I have this document from IBM, but I wanted other opinions and additional insight and any gotcha's.
