Today, I am releasing it to public, as it may serve good for some others too. Originally I developed Online Nandroid specifically for Xperia devices, but now I am releasing it for all android devices.
This tool, eventhough called "Online Nandroid", does not upload/save backups to any online/cloud services. Online here means that it does backup while phone is live or still running Android.
The short name onandroid is meant to be pronouced as o-nandroid or o'nandroid and NOT on-android.
Online Nandroid backups the below partitions to /sdcard/clockworkmod/backup directory.
- mmcblk0_start (for Acer devices)
- uboot (for MTK based devices)
- wimax (for Samsung devices)
- appslog (for HTC and Sony (Ericsson) devices)
- datadata (for Samsung devices)
- efs (for Samsung devices)
- preload (for Samsung devices)
- .cust_backup (for Huawei devices)
- flexrom (for Acer devices)
- custpack (for Alcatel devices)
- mobile_info (for Alcatel devices)
- boot (for HP Touchpad)
Feedback (especially ideas to improve) are most welcome.

The behaviour of Online Nandroid can be adjusted by using command line flags, some of which are described in detail below. Each command line flag has its longer counter-part and both forms can be mixed. For a complete list of command line flags and short descriptions, you can type:
onandroid -h OR onandroid --help
onandroid -c NAME OR onandroid --custom NAME
* Example: Use phone timezone for backup file name
onandroid -p OR onandroid --phone
onandroid -u OR onandroid --utc
* Good old backup mode (default).
onandroid -o OR onandroid --old
* Split backup mode (CWM6+ only).
onandroid -l OR onandroid --split
* CWM6 style incremental / dedupe backup mode.
onandroid -i OR onandroid --incremental
onandroid -gc OR onandroid --garbage-collect
onandroid -a PARTITIONS OR onandroid --advanced PARTITIONS
* TWRP backup mode.
onandroid -w OR onandroid --twrp
onandroid -w -ce OR onandroid --twrp --compression-enable
onandroid -w -md OR onandroid --twrp --md5-disable
* While using custom backup names, Online Nandroid will not allow an already existing backup name to be specified, by default. Trying this will return an error and halt backup. If you want to replace the older backup with a new backup, by using the same custom backup name, you can specify the below command line flag.
onandroid -c MyBackup -r OR onandroid --custom MyBackup --replace
