Corrupted manual encrypted backup

Question

Corrupted manual encrypted backup

Closed this issue a year ago · 4 comments

Vinfall commented a year ago

Steps to reproduce

Go to settings
Enable encrypt backups as zip option
Go back to local tab, select export vCard
Choose and select a folder when prompted (its path is sdcard:/Aaa/backup)
A toast saying Exported appears
Go to the target folder and try to unarchive the zip

Expected behavior

The backup can be unarchived successfully.

Actual behavior

Output:

$ unar contacts.zip
contacts.zip: Zip
Archive parsing failed! (Unknown error.)
No files extracted.
# I thought this password is randomly generated by Connect You
# \ is added to escape the dollar sign, and removing it does not change the error
$ unar -p "TuvXYRa\$XLak" contacts.zip
contacts.zip: Zip
Archive parsing failed! (Unknown error.)
No files extracted.

$ unzip -tv contacts.zip
Archive:  contacts.zip
  End-of-central-directory signature not found.  Either this file is not
  a zipfile, or it constitutes one disk of a multi-part archive.  In the
  latter case the central directory and zipfile comment will be found on
  the last disk(s) of this archive.
note:  contacts.zip may be a plain executable, not an archive
unzip:  cannot find zipfile directory in one of contacts.zip or
        contacts.zip.zip, and cannot find contacts.zip.ZIP, period.

Connect You version

6.0 (23)

Android version

Android 12 (originOS, iQOO)

Other details

When encrypt backups as zip option is disabled, contacts can be exported without error. And the vcf file can be imported back too.
This alone is not a problem if automatic backup is working as intended. It just unfortunately does not work for me either😞.

Have you tried extracting the file using Material Files? It works very well for me, and I don't see how this is an issue of the app.

Answer 2 · 2023-08-25T01:03:00.000Z

Yes, I'm using Material Files too. Opening/Extracting the file throws an error java.util.zip.ZipException: Archive is not a ZIP archive. I think it's caused by either OEM system or special characters. Would report back when I investigate further.

Answer 3 · 2023-08-25T06:16:07.000Z

Could you try to create only one or two contacts (and delete all others), and export an encrypted backup to see if the issue is there too? That might tell us whether it's an issue with something special in your contacts or something else with the device.

Could you try to create only one or two contacts (and delete all others), and export an encrypted backup to see if the issue is there too?

I did so and the issue persists. I also tried to remove characters outside \u0000 - \uFFFF, keep them ASCII only, and it's still the same error. And removing all local contacts and creating a contact named test with the number 1234567890 cannot solve this for me. So I guess this has nothing to do with the contacts themselves and I really have no clue how this happened now. But I wrote a Termux script to do this for me so feel free to close this if you want.

BTW, I noticed that if encrypt backups as zip option is enabled, Connect You will make *.vcf greyed out and only highlight those zip files when importing contacts. I need to deselect the option to import raw vcards. This is unexpected IMO.
