Hey @MorgothSauron and welcome to the restic community!
So as far as I understand this is, you have restic and rclone installed. Right?
If that’s the case, then the restic documentation for the rclone backend suggests that you can safely use the rclone environment variables and restic will honor them.
Other Services via rclone
Rclone can be configured with environment variables, so for instance configuring a bandwidth limit for rclone can be achieved by setting the
RCLONE_BWLIMIT
environment variable:
But there is also this:
The rclone backend has two additional options:
-o rclone.program specifies the path to rclone, the default value is just rclone -o rclone.args allows setting the arguments passed to rclone, by default this is serve restic --stdio --b2-hard-delete --drive-use-trash=false
So maybe this is what you were looking for in the first place.
Hope this helps And if so, please let us know.
