Where is my TWRP backups on encrypted Android? I encrypted my Android tablet which is a nexus 7. After that I did couple backups. Today I wanted to see the size of the total backups  so I open the TWRP folder on my sdcard. There is nothing there. I do not see them anywhere else either.

I made backups before encrypting my device. and TWRP backups always resided in the TWRP on the sdcard.

So where are the TWRP backups  after I encryted my device (via standard android enc). 

I am using TWRP Cyanogenmod11 Android 4.4.4 , using a recent build from this month.

thanks
Older versions of TWRP do not have the ability to mount encrypted file systems, so therefore, it cannot make backups.  In addition, TWRP only supports decrypting certain devices.  According to the TWRP2 Project Page, the only devices that they explicitly define as having decryption support are Galaxy Nexus and TouchWiz devices.
