[Bug] ‎Databackup does not follow the symlink of the data folder #164

Closed ZhymabekRoman closed 8 months ago

ZhymabekRoman commented 8 months ago

Describe the bug ‎Databackup does not follow the symlink of the data folder. For example I store Termux application data in second partition of SD card to reduce internal EMMC degradation. To do that I just make symlink /data/data/com.termux to external card folder.

To Reproduce Steps to reproduce the behavior:

  1. Go to 'Databackup'
  2. Select application to backup
  3. Start backup
  4. See that data is too small size

Expected behavior Properly saved data folder of application

Smartphone (please complete the following information):

Consider to add -h parameter in backup cmds

Consider to add -h parameter in backup cmds

How can I do that in DataBackup options?

I will implement it in settings.

Can you give it a try? Switch on Follow symbols in the settings first. DataBackup-1.1.0-alpha04-arm64-v8a-foss-release.zip

Thanks @XayahSuSuSu, seems like backup works perfectly. But there some problem:

  1. After restoring from backup, Termux says that there some permission error problem. I don't known what was a problem. I tried to test restore from same backup by fresh installing Termux without any linking data folder into external SD card and there's no permissions problem.
  2. I checked data folder and released that after restoring, data folder wasn't linked to external SD card folder as before backup, instead it was in internal memory

I don't known, can we says that it's bug, because DataBackup doesn't designed to handle such non common things. But anyway thanks for this functionality, if you see that this is bug of DataBackup I will appreciate if you fix that. For now I have some ideas to create FOS tool that will manage applications data transformation to internal and external card with and without root access.

And there some problem in Russian translation, very hard to understand some things. If I have some time, I will try fix them.

I tested termux backup/restoring, it works fine on my phone, so I think it may relate to the linking

Okay, thanks, I close this issue since problem is solved

This is not easy to implement in app and I think it goes beyond the features of the app.
