My Time Machine backups are done wirelessly to a Time Capsule located\nin a different room of the house. The backups are scheduled to run each\nhour on the hour using TimeMachineEditor. About once every several\nweeks the backup fails, delivering a message that the backup drive\ncouldn't be found. When this happens I'm able to "cure" the problem by\nunlocking Time Machine Preferences and manually running a backup, after\nwhich I relock Time Machine Preferences so that backups are again\nscheduled by TimeMachineEditor. Then things are back to normal until\nthe next failure occurs.\n\nSuggestions as to how this problem might be cured are most welcome.\n\nI'm running on the latest model iMac and the latest model Time Capsule.\nI'm running on the latest releass sof Lion (10.7.3), and\nTimeMachineEditor (2.5.3 (26)).
