BMR procedures for AIX are a no-brainer. Boot from installation media, restore your bootable mksysb backup image to get rootvg back, recreate the volume groups and filesystems, install the TSM client if it wasn't installed in rootvg, and restore all non-rootvg files. Easy, peezy. The problem with scripting a BMR procedure for Windows is that Windows simply lacks the required abilities. True BMR has the following requirements: 1. The OS must support booting from a network-attached image. NT cannot do this, and although I've been told Win2K will do it, I've never met anyone who has been able to make it work. 2. The OS must support the ability to insert missing drivers from local (or remote) installation media; this ability is vital for restoration to dissimilar hardware. (For instance, if the installation image lacks a driver for the NIC or SCSI adapter in the target box, it must be able to fetch that driver from installation media.) Windows completely lacks this ability during OS installation, except for SCSI-based RAID controllers. 3. The OS must support the ability to either overwrite hot (i.e., open) files, or support the ability to copy cold restored files to a hot location during a reboot. Windows can't do that. The application Bare Metal Restore (now published by Veritas, formerly published by The Kernel Group) found a handful of workarounds in order to get BMR to work with Windows. What I discovered in my work with BMR is that restores were absolutely breath-taking--as long as that restore is done in carefully controlled environments to exactly the same hardware. In the real world, on the two occasions that I witnessed, BMR failed to delivery despite the presence of a TKG engineer flown in to assist. We just couldn't get it to work. -- Mark Stapleton ([EMAIL PROTECTED]) Certified TSM consultant Certified AIX system engineer MCSE
