Hi, Ive recently got the Samsung galaxy tab 10.1 (wifi only), and its great but im very much used to pc, so i need a few gaps in my knowledge of android filling for me please. At the moment I am wishing to back up my tablet -mainly just the apps in case i need to do a factory reset in the future, but possibly user settings and browser bookmarks too. My first stumbling block is how/where data is actually stored on the tablet? My tablet says it has 16gb storage (obviously though, i realize some will be used for the system). I suppose the memory type is a flash card of some kind? if so is it just one 16gb, if it is then is it more or less partitioned like a hard drive can be? Or does it have more than one memory type ie a system memory on a flash card as well as user data on a flash card? This will help me in understanding the back up process as far as the back up process goes, ive found it a bit puzzling. im more than happy to just use a free app that backs up only my apps onto a removable sd card via a samsung to sd adaptor i have already. so i'd downloaded a few apps that seem to do the job; ultimate backup, AppMonster free, iSdBackup. then i mounted the sd card adaptor and inserted a 16gb sd card into it. it immediately showed launched the 'files' app, detailing the pathway /root/storages/usb/sda to it, so i opened 'ultimate backup', selected all apps, then hit the backup button, it showed a progress bar and informed it was backing up the apps before finishing by alerting me with a notification and vibration, (seems to have missed the wikipedia app but thats ok). now i come to check its done it okay, since i want to know its all worked safely and i can forget about worrying about it, so i turn off the tablet, put the sd card into my pc via a usb adaptor. it shows me a familiar folder name 'LOST.DIR', inside the folder is nothing and the sd card has used a mere 96 kb, despite knowing myself that the tablet has 900mb of apps on it and 'ultimate back up' app telling me it had successfully backed up my apps. so im a bit confused here to where im going wrong, if its saying its backed up the apps then where to? i havent set up an online account to backup my apps to and it doesnt seem that ive duplicated the apps on the tablet either, yet the sd card is just showing an empty folder when i insert it into the pc to check whats on it. also its worth noting that i go through more or less the same process with the AppMonster free app and i dont get any evidence (other than the app itself) showing me its backed up. with 'iSdBackup' it said it too had backed up my apps and when i put the sd card into the computer it did show a different folder name .android.secure however this was also just an empty folder too. all help would be greatly appreciated, thanks for reading.
