As a workaround, you can use the command line option --run-script-before-required
to launch a script that performs one or more tests. If one of the tests succeeds, the script exits with errorlevel 0, otherwise it exits with errorlevel 1.
Duplicati will abort the backup job if the script specified with --run-script-before-required
returns anything else than 0.
A script could look something like this:
@echo off
setlocal enabledelayedexpansion
set ErrLev=1
rem Check if connected to SSID "MyHomeNetwork"
for /f "tokens=1,2 delims=:" %%a in ('netsh wlan show interfaces ^| find " SSID"') do (set SSID=%%b)
set SSID=!SSID:~1!
if "!SSID!" equ "MyHomeNetwork" (set ErrLev=0)
rem check if IP 172.16.1.254 can be reached
ping -n 1 -w 500 172.16.1.54 > nul 2> nul
if errorlevel 1 goto :IP_172_16_1_254_Not_Found
set ErrLev=0
:IP_172_16_1_254_Not_Found
rem check if wired interface "Ethernet" is connected AND \\SERVER1\Share\Testfile.txt can be found
for /f "tokens=1,2 delims=:" %%a in ('netsh interface show interface Ethernet ^| find "Connect state:"') do (set State=%%b)
if "!State!" equ "!State:Disconnected=!" (
if exist "\\SERVER1\Share\Testfile.txt" (
set ErrLev=0
)
)
exit !ErrLev!
