Windows: Correct URI for repo on mapped network drive?

[m-reiter]

Hi,

I'm just trying to set up backrest on my Windows system. I'm new to restic as well, but I successfully managed to initialize a repo on my Synology NAS mounted via SMB as a mapped network drive (P:).

I can't however figure out how to connect to that repo in backrest. Here's what I have so far:

• With the restic CLI in Powershell , I can access my repo as "P:\backups\restic"
• When I enter the same in backrest's add repo dialog and select "Test configuration", I get a message "Connected successfully to P:\backups\restic. No existing repo found at this location, a new one will be initialized"
• When I then select "Submit" (with a second, empty repo), I get an error message

[unknown] failed to init repo: command "C:\\Program Files\\Backrest\\restic.exe init --json -o sftp.args=-oBatchMode=yes" failed: exit status 1
Output:
{"message_type":"exit_error","code":1,"message":"Fatal: create repository at P:\\backups\\r2test\\ failed: Fatal: unable to open repository at P:\\backups\\r2test\\: mkdir P:\\backups: The system cannot find the path specified.\n"}

I installed backrest from the release binary and it reports its version as "1.9.2-SNAPSHOT-899f30c". In the installer, I chose to run it as admin user since I intend to use --use-fs-snapshot. The successful interaction with the repo from the command line was done with backrest's bundled restic executable from within a PowerShell run as admin. Changing the backslashes to forward ones in the URI changes nothing.

Any advice? What is the correct way to specify the URI for a mapped network drive in Windows (10)? I searched here and on the web but didn't find any helpful info. Any help would be greatly appreciated.

Thanks in advance and all the best,

Manuel

am also new to restic/backrest and i ended up using restic-server, which by far is way more simplier and reliable than smb

on your synology you can run this docker compose file

services:
  rest-server:
    image: restic/rest-server:latest
    container_name: restic-server
    restart: unless-stopped
    ports:
      - "8877:8000"
    volumes:
      # Persistent storage for your backups
      - /save/location/for/restic-backups/:/data
    environment:
       - OPTIONS=--no-auth

in backrest/restic you use this repo url
rest:http://restic-server-ip:8877/repo-name/

if you want https and users auth you need to read docs, but locally on your own home network no outh/https should be fine
