Issue with backup. Contacts and SMS not backed up.

[soplaris]

Hello, I'm trying to back up my Samsung A21S with this script. I got everything started but encountered problems while backing up. Here is the command-line output (german):

Exporting contacts (as vCard), call logs as well as SMS messages (as CSV). adb: error: failed to stat remote object '/storage/emulated/0/open-android-backup-temp/.': No such file or directory Errors occurred while backing up . - this file (or multiple files) might've been ignored. mv: der Aufruf von stat für './backup-tmp/open-android-backup-temp/open-android-backup-contact*.vcf' ist nicht möglich: Datei oder Verzeichnis nicht gefunden No contacts found on device - ignoring. mv: der Aufruf von stat für './backup-tmp/open-android-backup-temp/SMS_Messages.csv' ist nicht möglich: Datei oder Verzeichnis nicht gefunden

Maybe someone can tell me how it will work. Doesn't seem to be a great problem, as I expect.

Thanks
