Help Cannot backup

ultradj83

Lurker
Dears,
I cannot succeed in doing a full backup.

Device is P5110 with android 4.0, rooted with CWM 5.5.

If I do a CWM backup to extSD it stops saying there's a file that is too big. Card is 8GB, totally free, and when operation is aborted there's still 2.7GB free.

So I decided to try with "adb backup -system -apk -noshared -all -f backup.ab".
At 1st run it went above 11GB so I killed it, at 2nd it stopped automatically at 3.6GB without any success or error message, so I converted the .ab file to .tar with "java -jar abe.jar unpack backup.ab backup.tar", but the resulting tar is corrupted, there's unexpected end of file and overall, in the file I see some apks and some content from sd, also with -noshared option.

This tablet will be used by a child so my target is to create a full backup to be restored in case of need.


Is the command I used correct?

Can anybody help me to understand what's wrong?


Thanks and best regards
 
I think the tab is telling the problem already. An 8GB card is probably too small to backup your device (which is probably 16gB?). Get a bigger memory card and try again.
