Backupset TOC

I wanted to clear up an error in a statement I made either here or ADSM.org about backupset TOC's. I previously thought that the TOC for a backupset was not portable. I was wrong. After looking into the DEFINE BACKUPSET command I realized that a TOC can be generated for a backupset after the fact. This feature helps make it more portable and requires that a TSM server be available to store the TOC. A TSM server is required to rebuild the TOC, but if the backupset is meant to be portable you can skip the TOC creation locally and allow the alternate TSM server to create it when you define the backupset to it.

TSM Express Flaw!

I don't know how many of you readers use TSMExpress but there is a flaw that has been identified by IBM. ComputerWorld has a description of the flaw here. So if you do have TSMExpress in use make sure you look into this.

DR Tests & System Restores

I know I have covered this before, but we have been doing DR tests and when restoring UNIX servers I find it easier and faster to use the Web/Java GUI to select all file systems required to restore the data than following the IBM guideline to build a small script that runs them serially. The thing I don't get is why they would push command line restore. Doing the restore file system by file system will require the same tapes be mounted multiple times where the GUI will restore all the data available on the tape for the selected backup. They do state that you can execute more than one restore simultaneously, but in every DR exercise I have run that would just cause tape contention since I do not collocate by file space. Unless I am wrong in how TSM handles a GUI based multiple file system restore wouldn't the GUI be the better solution when in a DR or full UNIX system restore scenario?

Of course this is all dependent on whether you have Java 1.4.1 or higher installed.
