Operating system error 5 (Access is denied.) when using MSSQL

[WilliamRockett]

Summary

I am trying to set up db-backup for MSSQL using the default configuration in compose.yml. I have manually created the test1 database as instructed. However, I am encountering a permission error from mssql when the backup performs.

Steps to reproduce

• Clone repo
• Run docker-compose up from folder examples/mssql

What is the expected correct behavior?

It should backup the test1 database from mssql without any permission error and copy the backup file to the backup folder.
