Online Nandroid Backup | Nandroid Backup without re-booting

Nandroid backups are usually performed in recovery mode. This means you would have to turn off your phone and reboot in recovery mode, which wastes a whole lot of time rebooting and a lot more time offline. For me, this has been a killer as I do regular nandroid backups. Having to reboot in recovery and finding missed calls, sms from my wife and friends is totally not accepatable for me. So, I set to develop an online nandroid backup tool which can do nandroid backups without switching off my phone.

Today, I am releasing it to public, as it may serve good for some others too. Originally I developed this tool specifically for Xperia devices, but now I am releasing it for all android devices.

This tool backups /boot (from version 5) , /recovery (from version 5) , /wimax (from version 5) , /appslog (from version 5) , /system , /data , /cache , /datadata (from version 5) , .android_secure & sd-ext (from version 3) partitions to /sdcard/clockworkmod/backup directory. The date format used for folder name is the same used by CWM itself and nandroid backups created with this tool can safely be restored using CWM. If you would want to have a custom name for backup folder, pass an argument with the name to the script and it will use the name.

Feedback (especially ideas to improve) are most welcome.

1. Rooted android phone
2. A terminal emulator installed on phone
3. Busybox
4. A working CWM based recovery installed
5. Some patience

1. Download and copy zip file to SD card
2. Reboot into recovery
3. Choose install zip from SD card, select zip and flash .
4. Reboot!

1. Open terminal emulator
2. Type su to obtain root
3. Type onandroid
4. Wait and watch

Custom Backup Name
* Example:
onandroid custom_name
* Please be careful not to include characters not allowed in filenames.

Timezone modifier
* Example: Use home/phone timezone for backup file name
onandroid -h
* Example: Use UTC (default) for backup file name
onandroid -u
* Note: UTC is used as default (if no timezone modifier is passed). This is to comply with CWM nandroid backups.

If you are getting error mkyaffs2image not found in path, try fix tool in this post.
