チタンバックアップ「フリーストレージスペースが不十分」エラー -- insufficient-memory フィールド と titanium-backup フィールド android 関連 問題

Because of my external SD card issue, I thought I should factory reset my phone then reinstall the firmware on it. Before I'd do that though, I'd have to back up my apps and their data so that I can restore it afterwards. For that purpose, I had been relying on Titanium Backup Pro, so I entered the app, changed the backup directory to /storage/emulated/legacy/TitaniumBackup (as the external SD card was unavailable) and attempted to backup all user apps and system data. A progress dialogue appeared and was stuck at 0% for about 30 seconds until it close and Titanium Backup displayed the notification 'Batch backup interrupted: Insufficient free storage space' despite having 7 gigabytes left on /storage/emulated/legacy.

I tried searching on Google for a solution - the only one that came up was to remove /data/app/com.keramidas.TitaniumBackup-1.odex but the file did not exist on my end. How can I fix this issue?

Clarification: My copy of Titanium Backup is a Pro version activated by a Pro key obtained from the Google Play store. There is no need for any external patchers, cracks or keygens.

This is due to the 'Mount namespace separation' setting in SuperSU being turned on (by default). Untick that, reboot and try your Titanium Backup operation again.

This happens because the permissions to app-created folders are restricted in newer Android versions, I believe. Ironically, I didn't have this issue on Marshmallow-based CM13, but I did face it in the Lollipop-based OxygenOS for the OnePlus One.

This happens due to some service change in kitkat. Some research on google showed that there is an app available to modify the platform.xml file. The app once run, prompts the user to allow it to go ahead and make the modifications to the above file. Everything works fine after this.

At TB's startup it always displayed a warning that SuperSU's namespace separation feature "might not work reliably on some platforms".

Well, I never faced any problems until a recent SuperSU update...

So disabling that option in SuperSU and rebooting solved the "insufficient space" on my OnePlus One/CM12.1.

This was the obvious solution before fiddling around with permissions etc.

(Titanium Backup)batch backup interrupted: insufficient storage space this solution work for me any one can try see if it work. I have a fix. I did a little research and found that you can edit /etc/permissions/platform.xml and add a group to WRITE_EXTERNAL_STORAGE

Add the media_rw group:

Done. Doing a TiBU right now to my external card. This may fix other apps that have issues writing to the card, I personally didn't find any.

Suggest that you do an adb pull of the file for safekeeping before doing this. If you pull the file, edit it, and push it back make sure the permissions are set to 644.

In recent versions of Android, paths under /storage/emulated/legacy only work for the apps that created them. If the OS doesn't know that TB created /storage/emulated/legacy/TitaniumBackup, then you'll get this error.

Try using TB to create a directory, then use that for your backups. Alternatively, use a path that doesn't start with /storage/emulated/legacy, like /data/media/0/TitaniumBackup. Either should work.

just go to super user-settings-untick "mount namespace separation" and reboot done!!

If you are using Magisk as your superuser manager, go to settings > mount namespace mode and select isolated namespace. Hope this helps someone!

As @Izzy said, this was an XY problem - I could have looked for another backup solution instead of insisting on using Titanium Backup. And I did - I used the adb backup feature (which worked when I rebooted my phone). In the end, I didn't have to restore the backup at all, but that's a different story altogether.

Open Preferences of your Titanium Backup. Then look for an option called Backup app external data in Backup Settings. Make sure it is NOT Enabled. Rather set it to 'Enabled if smaller than a chosen size' and set the size to 35 MB.

Some apps have a hefty amount of external data (stored in /sdcard/Android/data), particularly games which may span over several gigs. This option disables backing them up as they can be downloaded again.

Go into Titanium Backup settings

• Backup Folder location
• Storage provider
• Select "DocumentProvider storage"
• Allow access to ____

I have also faced this weird situation. I don't know whether it will work or not. But for me it works.

Install lucky patcher. It will automatically remove the odex file and you will be able to install Titanium Backup.
