I’ve been using this little piece of software for about a year now, and it’s really great. While the default one-hour backup of OS X’s Time Machine is definitely a nice feature, incremental backups per hour is not what everybody wants. Actually, the one-hour backup makes your external drive get full in a blink of an eye. So, to avoid this you can set the Time Machine to a predetermined schedule for your incremental backups. The best part, its free! So start downloading and customize your Time Machine Backups. Happy days!
TimeMachineEditor is a software for Mac OS X Leopard, Snow Leopard and Lion that lets you change the default one-hour backup interval of Time Machine.
Note: I know there are a lot of people having trouble with Time Machine on Mac OS X Lion and the WD My Book World Edition. After months of partial solutions I’ve come to a decent solution. I will post this later this week.
