No I don't imagine so. > Actually, is the "solaris" tree in the rescue perhaps > aimed toward Solaris x86? In that case, I suppose I'm out of luck anyway. No, it was aimed at Sparc, but no one ever offered to make it work -- I don't have a Sparc and the one I had access to I never had root permissions so could never run the scripts 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.

Well, I haven't looked at the Solaris rescue code for a long time, so I doubt very much that it is at all useful. It would be rather a lot of work to get it into shape. My previous recommendation still goes, have a "standby spare" on a separate Solaris system ready to go. If you don't have a spare Solaris system, the next best bet is to spend about $1500 for a suitable Linux machine that could at least host the Dir, FD, and database to restore your other machine. This would not be so simple though since it is not clear that restoring a database written on a Solaris to a Linux machine would work. In addition, there would be some rather important changes needed to your SD conf file because of drive naming convention differences ... Now that you have had this problem, you may want to quickly glance over the Rescue chapter in the manual, and more importantly read the Restore chapter of the manual. The later has a lot of suggestions for how to recover in case of disaster. Any comments about the doc in this area would be *much* appreciated since there is nothing like someone who has just been through it to know what the real problems are -- I can only guess ... ------------------------------------------------------- Using Tomcat but need to do more?
