Android 6.0.1
Starting about two-three weeks ago, i've noticed that automatic backup on SD Card is not working.
Backing-up Applications freeze always at 50%.
I tried a back-up via Xperia Companion, i choose only 'Settings' and 'Other', and somehow 'Other' is freezing.
What can be the cause? How can I investigate?
Solved! Go to Solution.
Problem solved! (08.01.2017)
Launching Xperia Companion, i have updated to last version (1.9.2.0), and try to backup only Other, like usually update failed, but this time indicating me the application causing the failure.
I have uninstalled the app (My Vodafone in my case), and after that i successfully made a full backup of everything both on Sony Device (using standard backup app) and using Xperia Companion.
So, thanks Sony for the update of Xperia Companion, nice job!
Hi @Kiu_RO,
I'm sorry to hear this. 
It sounds like there is something in your device that cannot be backed up if it only works when you don't include the other category. I have requested more information regarding what is included in the Other category, I will let you know when I know more. 
When you do a backup to your SD card, have you tried to uncheck the box for apps? Does the same thing happen then?
Is something very strange...
Last successful backup on SD Card, was on 12.09, all items checked
(i have scheduled automatic backup at 7 days, and starting from that time, nothing successfully).
Always at Applications, at 50% freeze.
Unticking Application check-box, create the backup with no problems.
I've tried to unninstall some apps, trying to imagine what app i have installed after 12.09, but it's more like a "guess" process, not something correct.
I don't know how to investigate at that percent 50 in fact what app is causin the freeze.
Or, do i have the possibility with a third app to investigate the exact date when a new app was installed. I'm thinking to try to disable all apps installed after that date, and to see if this solve the freeze problem at 50%.
Any help on this matter is really appreciated!
Thanks
Very strange situation: i also try to manually create a backup, only 'Applications', and i've changed the location, this time online account, not SD Card. The backup freeze from begining at 0% (not 50% as in the situation of SD Card)...
What could be the reason, is something behind blocking this...?
I accidentally discovered another thread similar with this, and sad to say, was marked as solved, but NONE of the solutions / ideas proposed there are in fact working...

The Other category performing a backup using Xperia Companion is simply all other applications that are not included in the first categories. This includes any third party application installed on the device that supports Backup & Restore.
If you experience that the backup fails when Other is selected you can try the following.
I followed your instructions, still no changes.
Backup is freezing, either on phone or via Xperia Companion...
