Re: backup stgpool from one server to another?
You're welcome!.

Re: backup stgpool from one server to another?
Yes, you can use one TSM server as an "electronic vault" for another TSM server. Look in the Administrator's Guide under the topic "Using Virtual Volumes to Store Data on Another Server". It may not be the best approach, however: * The data is sent from the primary server to the secondary server via TCP/IP. How well it works for you will depend a lot on the available throughput you have, and the amount of data involved. * It may not work like you want: Server-to-Server virtual volumes create an "electronic vault", not a "standby server". If your primary server goes down (or burns up!), the data is safe on the "other" TSM server, but cannot be restored directly from the other server. You have to recreate your pirmary TSM server image first. * First let me say that I don't even know what "on demand" is, but I'm not sure what you mean by "temporary stuff". If you are talking about backups, TSM doesn't really understand the notion of "temporary". How will you get those backups to expire off the "other" server? Archives are a better choice for something that is "temporary". * "Virtual" volumes also have to be reclaimed, and that involves transfer via TCP/IP again. * Have you considered creating a second copy pool and just moving the tapes of this "temporary" stuff to the other server's location? It's usually faster and easier to manage than virtual volumes, if you have a lot of data. * I assume from your question that your TSM servers have separate libraries. I don't have enough information about your config to say for sure, but if your library will support it, a better solution may be to use a fibre connection to let your 2 TSM servers share one of the libraries, and have your TSM "on demand" server write its copy pool into the other machine's library. Hope that helps.
