I can tell you that to some extent I am already doing what you described. I have two STK Powder Libraries with 10 9840FC drives between the two libraries that are located in different building (about 2 miles apart), a Win2000 Cluster in one location and the disk for that cluster in the second location. Everything is connected by fiber switches and the 2 fiber switches are connected through dark fiber. The database backup is performed to the library were the physical server nodes are so that it is away from the disk that contains the live database. The Library that is with the servers contains the tapepool and the second library were the disk are contains the copypool. Disaster recovery is kind of like this.
If building with physical servers, primary tapepool and database backup is destroyed then I would build a server in the backup location were the disk is located (database is already there in production) and then mark the primary tapes as destroyed. Should be up and running in the amount of time that it take me to build a Win2000 machine for the most part. If building with the disks are destroyed then I would have to get new disk connected to SAN and then restore the database and delete are copypool tapes and recreate them. The Win2000 server is already built so the recover would be the time it takes to restore the database. -----Original Message----- From: PAC Brion Arnaud [mailto:[EMAIL PROTECTED]] Sent: Wednesday, February 06, 2002 5:10 AM To: [EMAIL PROTECTED] Subject: 2 servers and libraries , 2 sites, I want super disaster protection ! Hi Gurus ! I have a question concerning security : we currently have one TSM server (H80 AIX server) connected to a 3584 library. As our library reaches it's capacity limit, we plan to buy a new one, and possibly another server, to build a double server and library solution. I'm looking for an improved disaster-resistant solution, that could give us the opportunity rebuilding the whole system, case one server and it's library would be destroyed. The actual situation : we do nightly backups, followed by a complete stgpool backup and dbbackup that are stored offsite. We also own DRM. What we plan to do : split our backups data over two libraries, to benefit of the increased tape drives quantity and tape capacity, and to split DB data over two systems (therefore accelerating expiration process etc ...). The two server-libraries couples will be installed in two different locations, to minimize risks in case of fire, earthquake ... How would you build such a solution, that would give you the opportunity rebuilding the whole system in case of total destruction of one of those sites ? Would you use virtual volumes for crossing Dbbackups and STGpool backups ? Any suggestion will be welcomed ;-). Thanks in advance !
