Re: QFileSvr.400 and *IMGCLG

As I understand it they are tackling the remote backup piece in a slightly different direction. Rather than have only the catalog's images on a remote machine I expect some sort of virtual tape drive that points at a remote virtual drive or possibly directly at the remote image catalog. Initially I think it will be only across LPARs due to speed limitations on networks. The theory would be that you'd have one partition with lots of big disks and the physical tape drives attached there. Backups would run through the virtual tapes to images on the big 'backup' partition. These backups could even be in parallel depending on I/O capabilities of the 'backup' partition. As the backups are completed the virtual tapes can be copied to physical tape thus maximizing physical tape use and reducing cost. It's possible they would do the same thing with optical image catalogs thus allowing at least PTF and software installation from one set of images on this central partition. As Marty mentioned though using such an image catalog for i5/OS upgrades would mean some amount of communications getting to the 'remote' catalog entries so this would be a tad more challenging, though clearly not impossible especially if implemented on LPARs rather than physically separate systems.

It might be nice, but I imagine that it would be tough to do. Let's say
you're upgrading the OS or putting on PTFs. There would have to be
enough communications support up and running to allow the remote image
to be read. Just speculating.

Thanks for your reply.
It's a shame it doesn't work though. Seems like a missed opportunity to do a simple cross machine/site backup.
