First off, good luck with the test.

Just curious, why wouldn't you bring your boostrap, and/or index files? Scanning a tape takes quite a while, especially one that is close to 1TB
in size.   Also, the name of the server could come in to play, but I'm
not sure since you are doing the scan.

When I had to recover over 90 servers (Katrina), it was a lengthy (but
straightforward) process of recovering the index of each server to
restore. Once the index was restored, DR people could then start all of
their restores.

In your case, a boostrap, some renaming the res directory, and then
recovering 1 index could be done in a very short time frame. I think it
would be much quicker than scanning the whole tape.  Maybe others have
had different experiences with tape scanning.

Let us know how it goes.

Thanks. I was unclear. I don't care about the ability to recover individual files, although I will probably be asked just to recover two or three specific savesets via the scanner utility. I will know which saveset IDs to recover because I archive that information via an "mminfo -v" daily.. The scanner man page says it accepts a SSID as an argument. One thing I am not clear on is how scanner will know when a saveset spans multiple tapes.

So, unless I am really off base, all I need to do at SunGard is create a pool to match the one I use for doing the backups, and also a client resource. I also assume that I will need to recover to a different path and possibly the DR client might have a different host name than the production client. But from what I can see, this can all be done without recovering my production NSR server if I approach this from the standpoint of migrating data rather than doing a DR situation.
