I have Retrospect set up to do a verify after each backup. This means that it reads each (just-created) backup file and compares it to the source file to ensure data integrity and ability to do a restore. If the data in a file changes between the time of the backup and the time of the verify, usually a few minutes, there will be an error in the log. Usually this is inconsequential and not a cause for concern. The backup file is still OK, but does not contain the most recent change(s). But Paul Welty is describing a different pattern of events. He describes a situation where the file changes between the initial scan and the backup of a file. I have not yet seen Retrospect report an error for this situation. And I don't know why it would cause Retrospect to fail to backup the file. I am using Retrospect 5.0 Desktop to backup 3 Macs: one running OS X 10.1.5, a client running X 10.1.5, and another client runningh 9.2.2. Two of these Macs have Entourage X SR1 installed. -- Julian Vrieslander <[EMAIL PROTECTED]> -- To unsubscribe: <mailto:[EMAIL PROTECTED]> archives: <http://www.mail-archive.com/entourage-talk%40lists.letterrip.com/> old-archive: <http://www.mail-archive.com/entourage-talk%40lists.boingo.com/>
