IMPORTANT NOTICE: 0 Backup is currently deprecated. It still works, but no active development will be done (not even to follow Android versions). This page will remain available for current users, but we strongly suggest not to install it unless you know what you are doing. If you need the features of 0 Backup, you will probably like FolderSync, which provides almost all the features of 0 Backup and many more (although probably with a larger degree of complexity, since it does many more things).
0 Backup is backup solution for your Android device, allowing you to fully backup your external SD card to your own computer.
Think about it: your contacts and calendar are probably synchronized to your Gmail account, your mail corporate server or your MS Exchange corporate server, but what's about the data in your SD card? The documents you have created with Documents To Go, Quick Office or any other office suite; the passwords you keep within KeePassDroid; the photographs and videos of your family; the quick notes you take with your favorite notes editor; all of them and many others live in your SD card, so most of your data lives in your SD card. Back it up!
Other backup solutions say to make a backup of your phone, but if such backup is kept only on the SD card of your phone, it is still in risk of being lost or stolen. 0 Backup can help you back up also such data form the SD card to your own computer.
Other backup solutions store the backup on online storage servers, usually subject to a monthly fee. 0 Backup does the backup to your own computer, so no extra or hidden fees apply.
