So might Droid Bionic users... I was thinking about this the other day when my SD card on my phone died(grr.. lucky for me I had a week old backup!).
I plug my phone into my laptop every night when I go to bed to let it charge. Are there any apps out there that can do a backup of your phone(/sd-ext and /sdcard) when the phone is plugged into the computer? I figured by now someone would have invented one but some searching has come up empty handed.
The other option I guess would be a program that would let you backup the /sdcard and /sd-ext over wireless LAN using Windows shares or FTP. FTP would be my last option because it does not have any protection from corrupted network packets.
