not so long ago i developed a bmr solution for linux. I did the following Dow loaded the superrescue cd ( a redhat 7.2 live cd). Then customized this cd (deinstalled stuff you don't need and install stuff you do need) In my case i installed the tsm client and webmin. Recompiled the kernel to include some network drivers/scsi we have in our servers. Then recompile the cd and burn it. (instructions do come with the cd) We have already scripts running on the clients which collect system info sand send this to a central email address. This includes partitioning information. When a machine dies (or for testing) 1 - grab another piece of hardware, the more equal the better but it is ok to have something different in most cases depending on your situation 2 - grab the system info from the to be restored machine 3 - boot the new hardware from the rescue cd 4 - recreate partitions etc 5 - restore your data from tsm (you have the client installed on the rescue cd) you only have to change the nodename in the dsm.sys file .You can use the data from the standard backup (no image backup needed) 6 - adjust some stuff in the config files if other hardware (like scsi to ide ) 7 - reinstall lilo or grub (using chroot) 8 - make some dirs (initrd and proc) 9 - reboot
i tested it and it works pretty good for redhat and suse.(on software and hardware raid) To rebuild a machine it takes approx 30 min human intervention, the data restore time will vary ofcourse. You will need good understanding of the linux os. (esp. what it is doing when booting)
have fun mvg

Anyone care to share any experiences on doing Linux BMR?
I've read through the redbook "Disaster Recovery Strategies using TSM" as well as the Linux-Complete-Backup-and-Recovery-Howto. I have AIX background, and trying to equate things...is the stage-1 backup where you tar the system like doing the mksysb on AIX? Except it's not bootable. How often would you need to do this stage-1 backup? If it's not as often as my incremental backups with TSM, then the restore with TSM would then have to include the system files to pick up any changes....right?
