That's a good idea. I just checked and, based on the names of the folders, there appears to be only one per hour. So, this suggests that the listing within the Time Machine app is reporting two backups per hour when in fact only one is being performed (or at least only one is being kept in the usual location).

I opened the Time Machine app today and, as usual, there are the tick marks along the right side of the screen that show when the various backups were performed (when the mouse hovers over a given tick mark). Ideally the backups are about an hour apart. In my case, there are pairs of tick marks with the same time listed. That is, the last two tick marks show exactly the same time, the next two tick marks also show the exact same time (though an hour earlier), and so on. I don't know if two backups are being performed each hour, or if the listing is just messed up. Has anyone seen this? Does anyone know how to fix it? Is there some preference file somewhere that is messed up? > > Thanks in advance for any help you can give me, > > Gregg _______________________________________________ MacOSX-talk mailing list MacOSX-talk@omnigroup.com http://www.omnigroup.com/mailman/listinfo/macosx-talk
