We now have another way to Backup and Restore data on any device that has been update to iOS 4 or greater. The nice part about this is that it will use the USB cable, so there is no need for Wi-Fi like with Time Master Central. It is a bit more work than TMC, but it is another way to do a backup.
In iTunes, select your device from the left side column. Select the "Apps" tab (top). Next you will need to scroll down below the Apps section, to the lower part of the screen, where you will see the "File Sharing" section. Select "Time Master" and then you will see some items in the "Documents" list. The main file is named "database.rsd". "Save to..." a safe place on your computer. You will also want to rename it something that tells you when it's from (date wise). For example rename it to "database 06.21.2010.rsd". Whatever you do, DO NOT delete the database.rsd file from the Documents folder or you will loose the data (unless you have a backup that you can put back in there).
If you need to Restore the database, you must rename it back to "database.rsd" first (this is mandatory). Click on the "Add..." button. "Choose" the file and and when prompted you will need to "Replace" it. Your iPhone should be restored with the contents of that database file.
