I also received lots of mail from folks interested in this very topic. Rather than responding to each person directly, I am going to post the definitive word on the subject. Thanks to everyone for expressing an interest. Special thanks to Kirk Mckusick for taking the time to respond personally.

Date: 25 Nov 86 17:44:46 GMT There is a rumor around here that Mr. M. K. McKusick has written a paper on the backup of a live file system. It would certainly be appreciated if anyone could respond to me with the title of this illusive article (if it *really* exists). Thanks in advance for any cooperation. Lee Casuto Mail: ...ucbvax!hpda!lkc I hate to disappoint you, but no such paper exists. In fact I have gone out of my way over the years to make it as clear as possible that `live' dumps are NOT always going to work! The problem is that they usually do work, particularly if they are being used to extract individual files. But full incremental restores are likely to bomb out, and of course these are the ones that are most critical. Kirk McKusick
