Force backrest to use its own internal restic binary instead of system installed

[notDavid]

Hi there,

So the readme says:

Backrest will use your system install of restic if it is available and matches Backrest's required version. Otherwise it will download and install a compatible version of restic in its data directory. Backrest will keep restic up to date with the latest version. You force use of a specific restic binary (or non-standard version) by setting the BACKREST_RESTIC_COMMAND environment variable to the path of your restic binary.

I'd like to FORCE backrest (running as user root on macOS) to use/download its own internal binary, and keep that updated, despite of also having a system installed version available (installed by HomeBrew, which is also read/write accessible to other users.)

Is this currently possible ?

I tried setting BACKREST_RESTIC_COMMAND to /var/root/.local/share/backrest/restic and putting the binary there, but that does not seem to keep it updated / download the latest version:

2025-01-26T12:03:39.383+0100 �[33mWARN�[0m restic binary "/var/root/.local/share/backrest/restic" may not be supported by backrest: want restic 0.17.3 but found version 0.17.2
