RE: Recovering NWSD

The time it takes to save the IFS depends on the number of objects saved. The size is secondary! We had a directory with over a million objects that we were finally allowed to purge. They didn't take that much space, but the system has to write an individual entry on tape for each object. Backup time dropped by more than an hour!

If you are able to perform an Option/21 (complete system) backup, rebuilding the system doesn't take long from the backup. What takes time is re-loading all of the data!

An Option/22 backup saves the OS part of the system (and the IBM part of the IFS). It doesn't take long, but you should be able to boot from the /22 backup and rebuild the system without having to reload all of the original DVDs! It should include the OS, all program products, all PTFs, device descriptions (ie RTVCFGSRC), &c.

I didn't see any mention of what kind of storage you're using. Disk? Flash? Directly attached? V7000/V9000?

Bit of an odd query, but what is the impact of rebuilding a virtual iSeries from scratch (if you have retrieved the config via RTVCFGSRC) as oppose to restoring it from tape?

The reason I ask is that the image we have on tape is huge. We save the entire IFS to a VTL using BRMS only on a restricted state backup and it is taking up a lot of space on our VTL and takes a long time. We also backup the virtual iSeries in the normal way, again using BRMS.

If I could skip backing up the NWSD object, it would help.

Note: the virtual iSeries is test, not live and it is hosted on a development machine.
