You can also alter this setting via the terminal, by running the command: sudo defaults write /System/Library/LaunchDaemons/com.apple.backupd-auto StartInterval -int n Where n is equivalent to the number of seconds between backups. one month would be: 60 seconds x 60 minutes x 24 hours x 30 days = Far, FAR too long to go between backups! Seriously! There's no reason to not have Time machine on. The first backup takes forever, subsequent ones take almost no time. Putting long delays between backups actually makes the problem worse, because Time Machine sees that a LOT of time has passed and I'm pretty sure that triggers some deeper examination of things to catch all changes. Seriously. If hourly is too long, change the value of n in the line above to 21600 (6 hours) or 43200 (12 hours), or just switch to Carbon Copy Cloner. Truthfully, I use BOTH. Time Machine's great advantage over CCC is that I can go back in time and undo changes to files; you can do this with CCC, but it's not nearly as intuitive and easy. CCC lets you have an 'instant restore' (just boot off your backup drive, and restore it to your main drive, or use it as a source for Disk Utility's Restore command.) They're complementary systems; either one lets you recover everything easily, CCC works better on smaller drives, TM lets you roll back changes if need be. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.
