Is there some new mysterious security BS in android 4.3? I've been setting up my new 2013 Nexus 7, and I'm trying to get rsync to work to backup the files Titanium Backup stashed on the sdcard, but it says "permission denied" when I try to copy them. I can't find any problems with any permissions: Here I am in /storage/emulated/legacy/TitaniumBackup and an ls -l looks like: -rw-rw-r-- root sdcard_rw 8271 2013-07-28 19:48 xcxin.filexpert-20130728-234815.properties -rw-rw-r-- root sdcard_rw 4029 2013-07-28 19:48 xcxin.filexpert-20130728-234815.tar.gz -rw-rw-r-- root sdcard_rw 8308712 2013-07-28 19:48 xcxin.filexpert-9349ab6bc87f0af18def492f0576caba.apk.gz It saves the .properties file OK, but can't save the .tar.gz file which has the exact same permissions. Anyone know what is going on? Am I going to have to make the rsync binary setuid root?
