If a file env exists in the folder ./jobs/ it will be sourced by the backup scripts.
Here you can set custom environment variables.
A common usage is extending the variable PATH to execute binaries that are not located in any directory.
Example:
This might be helpful on MS Windows. If you put the restic binary “somewhere” eg. c:\portable\restic\restic.exe then you can add the path to the env file:
PATH=/c/portable/restic/:$PATH
