Backup /data

Tue, 22 May 2012 10:00:33 GMT

Hello.

Analyzing the system in the .73 firmware I have seen that you i can´t make backups of our apps and their data due we haven´t permissions on the /data filesystem. In the /system you allows read but in the /data we should have read/write/execute but we can not access it, with the consequent problem of can´t make backups of our data ( /data/app ; /data/data )

Any solution?.

you need to root your phone to access that data, rooting could void your warranty

The most important folder , /data/data , have permissions 700 or less. This indicate that have all permissions for root ( read/write/execute ) but none for group and others.

Access with apps to explorer folders, or with adb console is restricted. Only root can access to it.

And...i have programs to make backups of SMSs, Call Logs, ...and i have made backup of /system/app . But is a error give access to /system/app and don´t give access to /data/app or /data/data . The most important personal folders ...restricted.

I buy a expensive mobile and i can´t make my personal data backup and cant make a system backup !?!?

you do need to root to do so, it's not just sony it's across all Androids.

My old models of android, since android 1.5 to android 4.0.3 , without root , had access to /data/data and always have been make my backups. Other models restrict access to /system/app , but never to /data/app or /data/data , because this is user filesystem.

The filesystem is /data and in it , the folder app is personal apps. And personal folder of personal apps and system apps normally is /data/data or /data/privatedata, ....

Its a big error can´t access to personal folders .

Who can i make a screenshot if i haven´t access to it ???

Go to / and then access to /data . This is the user filesystem but don´t have user permissions . Only root permissions.

either or you need to root your device, I'm surprised you had that option before. You will need to root your phone then either do it manually or use titanium backup

You say me that if i don´t make root I can´t make backups of MY DATAs ?

In my old Samsung, HTC, .... in all models and systems android from 1.5 to 4.0.3 , WITHOUT root and similar to any linux systems, the user filesystem have read/write permissions to one group that include system user. And root is restricted, but /data have correctly permissious. In XperiaS the /data filesystem have wrong permissious. And it´s severous error.

if you use root Explorer you can't access it, but if you use OI File Manager you can give it a shot

But , what doy you expect to see in the screenshot?. The filesystem /data must have full permissions for user because is where you store the apps and user data and does not. Among the /data with RootExplorer, OI File Manager or adb shell does not allow it because Sony mistakenlyleft him with access only by root. And it's a big mistake that a user does not have filesystem access to this filesystem. And it's a big mistake due root terminal to do so,when in very many cases we can not to have it because the bootloader are closed.

Root Explorer:

OI File Manager:

Adb Shell:

The access to /data is correct but in it , system user can´t see or access to /data/data or /data/app

And here the evidence that the /data/data and /data/app exist because in ALL ANDROIDs this is the folder to personal data and personal apps. And without access we can´t make backups.

My XperiaS, like that of millions of users is taken from an operator and has the Allow Unlock Bootloader = NO . We can´t make root.

I would keep checking the XDA Forum for alternatives

Re: Backup /data

Wed, 23 May 2012 13:25:06 GMT

There are no alternatives. It is a problem of rom / Sony original firmware.

This problem we have millions of users with "Allow unlock bootloader = NO " in HTCMania, XDA Developers, ....
