How exactly did you "move" the backup tree from A to B? Did the move operation preserve all the attributes that your backup operation normally preserves? If not, the first backup would have fixed all the attributes and, if mtimes were not preserved, retransferred the files. If your computer was always on and your external drive A was always mounted, there's another possible explanation. The inodes and directories on drive A were probably cached in RAM, allowing the backup script to conclude very quickly that no files needed to be transferred. However, the first time you backed up to drive B, inodes and directories had to be read from the drive, and from then on they were in cache. The trouble with this explanation is that one would think drive B's inodes and directories would be cached as the backup tree was moved to drive B. -- Matt McCutchen [EMAIL PROTECTED] http://hashproduct.metaesthetics.net/ -- To unsubscribe or change options: https://lists.samba.org/mailman/listinfo/rsync Before posting, read: http://www.catb.org/~esr/faqs/smart-questions.html
