I need a way to back up my whole Android device on my PC, which is running Windows 7.

I don't have USB cable for my phone, but I have wireless router, so my best option is using Wireless connection.

I have encrypted my rooted Nexus S device, and now I am locked out of accessing SD card via recovery. The only way to decrypt my device is Factory data reset, which will erase all data on my phone.

Before doing that I need to backup all my SD Card content, Apps, App data content to my PC. I need something much like Ultimate Backup Tool, but instead of recovering data through USB cable, using wireless instead.

Not a duplicate, but a lot of information:… – Al E. Mar 4 '13 at 17:05
Are you rooted? – Evil Angel Mar 4 '13 at 17:07
Yes, I updated my post. – xcyteh Mar 4 '13 at 17:50
Definitely give AirDroid a shot. It's an excellent tool for accessing the filesystem of your phone over a wireless network. – Nathan Osman Mar 5 '13 at 8:44
I did it that way, I backed up all the apps using Rom Toolbox, and than used Airdroid to transfer SD card content to pc, which later I restore to Android the same way. – xcyteh Mar 5 '13 at 11:54

Summing up the solution from the comments and expanding:

This process basically includes two steps:

  1. Create a backup
  2. Transfer it to the Windows PC wirelessly

A further pre-condition for the following is that the device is rooted, which is the case here.

Create the backup

Depending on what you need to backup, there are different good solutions available (you can see the backup tag-wiki for more information):

All three options store their backups on the SDCard. So if your device features a microSD slot, you could even simply take out the card, and attach it to your PC using a card reader. This generally works without a cable, and such could also count as "wireless" :)

One thing you might need to care for manually are the media files, and other downloaded/manually created stuff. Usually, this is stored on the SDCard as well – but that could be the internal one, so in case of the "card-reader option" you might need to copy stuff to the external card manually, which can be done with a good file manager such as ES File Explorer.

Transfer via WiFi

Now for the WiFi transfer. This can be done with the just mentioned ES File Explorer, which includes a "Samba client" to access Windows shares: Just share a drive from your computer, and then copy all files over. This also can be done "the other way round", pulling the files: with e.g. Airdroid you can access your device from any web browser. Airdroid includes a file manager, and lets you upload and download files.

Another more elegant variant, especially if you want to automate things, is to use a sync tool. Here you might want to take a look at FolderSync: As the name suggests, this app lets you synchronizes files and folders. Like with ES File Explorer, you can use Samba/CIFS here to access a Windows share.

Elegant permanent solution: Set up scheduled backups with Titanium Backup, and set up a matching sync interval for TiBu's backup directory with FolderSync. That way you always have an up-to-date backup off-board your device, in case of brick/loss/whatever.
