The machine was backed up by Data Protector, so I was able to boot the other copy of Solaris 9 and have data protector remote-installed and be on my way. What I lost was an install of Bacula that had the DIR, SD, and FD. Therefore if I had a rescue that only included the FD, I'd still be up the creek. Probably my most likely plan is to backup the base OS with Bacula just to get to a restore point (far enough up that I can have Data Protector installed) and then worry about restoring the rest from the datacentre backup. The situation with this box is that it is a webserver as well as Bacula director/sd/fd. I am concerned with my ability to quickly return the machine to service to continue making backups -- the other mission of the box is not my responsibility. The root volume is now mirrored and this SHOULD never happen again, but we know how that goes. > IMO, the simplest and quickest way to get a Bacula server back up is first to > have a Bacula rescue disk, or perhaps the new Knoppix remastered disk that > includes the Bacula rescue files, AND a separate machine where you can at > least temporarily bring up a Director, SD, and a database.

This is a Sun UltraSparc E450, not a Linux machine. Does Knoppix exist for UltraSparc? Actually, is the "solaris" tree in the rescue perhaps aimed toward Solaris x86? In that case, I suppose I'm out of luck anyway. > In most companies, the cost of having a "hot spare" is about $300 for a > second > SCSI card, and maximum 100 MB of disk space holding Bacula and a dummy > catalog database.

I also have 3 SCSI controllers (a total of 6 channels) so I'm set in the case of any kind of large-scale failure, but I still need to be able to restore this machine in the case of a disaster of a larger scale. I likely will not have extra hardware for a backup director, so I'd like to find out how I can make a complete enough rescue disk/disc to get back on my feet. Perhaps some builtin Solaris utility would be a better idea, then restoring Bacula from Data Protector as I did this time. However, my datacentre is relatively slow with restores and this time I missed 3 days of backups by the time the box was back in shape. - -- ---- _ _ _ _ ___ _ _ _ |Y#| | | |\/| | \ |\ | | |Ryan Novosielski - User Support Spec.
