In theory, a journaling filesystem will do that. Veritas is a good name for these. The problem with most of these is that a $300 UPS is cheaper and more reliable. Most such filesystems are attached to such an increase in complexity that the most common cause of curruption is a filesystem code bug. Even a UPS does not help you then. Simon
