The location depends on what mode is the Android currently running in. When you use adb
while running recovery, the location is like /data/media/TWRP
(or /BACKUPSdata/media/0/TWRP
). When you have the system running, the location is /sdcard/TWRP/BACKUPS
.
If you do not want to install Droid Explorer as advised by Hariharan G, you can use adb
from command line to copy the files:
While running recovery:
adb pull /data/media/TWRP/BACKUPS BACKUPS
While running normally:
adb pull /sdcard/TWRP/BACKUPS BACKUPS
(Those are paths I see for backups with TWRP 2.7.1.0 on rooted Motorola Xoom with Android 4.1 and 4.4.4 - TWRP prints the path valid while running in recovery when performing backup, you can check it in the log)
