I have a Galaxy Tab (T-Mobile version). The file locations on this version are somewhat different than most other Android devices. Specifically, the internal memory is partitioned into a system/user area and an area that it identifies as "sdcard". I have an external micro SD card and it is identified as a folder on "sdcard" called "external_sd". By default, Titanium Backup places the backup files on the SD card. Unfortunately, on these T-Mobile Tabs, that means that the backup files are actually located on the internal memory. I would really prefer to have the files located on the external SD card. I can't find any settings in TB to change the location of the backup files. The only alternative I can see would be to manually copy the files from the "sdcard" to the "external_sd".
