NethVoice Module Backup Restore Fails with Errors

[Amygos]

When attempting to restore a backup of the NethVoice module, the restore
operation fails. The process triggers several errors related to container
management and missing files or directories, resulting in the restoration being
aborted.

Steps to reproduce:

1. Create a backup of the NethVoice.
2. Attempt to restore the backup onto the same or a new NethVoice instance.
3. Observe the failure during the restore process.

Expected behavior:
The restore should complete successfully.

Actual behavior:
The restore process fails with errors indicating missing files/directories,
container access issues, and failed file copy operations. The task is marked as
aborted. The GUI displays an error window summarizing the failed steps.

Components:

• NethVoice module version 1.3.3
