Restoring backup from samba fails #6544
Description
Describe the issue you are experiencing
Restoring a backup from a samba share fails. The backup was created by the same HA instance a few hours previously, so there should be no issues with write permissions. The temp folder is created correctly, but the extraction of the tar file fails.
Copying the file to the local backup storage and restoring from there works as expected.
What type of installation are you running?
Home Assistant OS
Which operating system are you running on?
Home Assistant Operating System
Steps to reproduce the issue
- Add a samba share as backup folder
- Create a backup
- Restore the backup
