Windows 8.1 Task Scheduler Won't Execute Rsync/SSH Without being Logged On

问题

I've created and scheduled a batch file in Windows 8.1 (to perform rsync offsite backups through an SSH tunnel) and I can run it:

manually
through task scheduler manually when I right click -> Run
through task scheduler automatically when I am logged on and it's scheduled to run at a given time

... but when I'm not logged on, it just sits at "Running" even though I've set it as follows:

user=me (I'm a member of admin group)
run whether logged on or not
run with highest privileges

I can see in Task Manager that rsync.exe and ssh.exe are running, so it must be hanging on the rsync/ssh call. That leads me to believe the problem is that, even though I've explicitly set the user name, something isn't really running as me? (sidebar: I've also tried running the task as SYSTEM user - no luck there either)

The command I'm issuing looks like this:

rsync --archive --verbose --human-readable --hard-links --delete --exclude '*.log' --exclude '*log*.*' -e  "%CWRSYNCBIN%\ssh -p 22103 -i C:\Users\test\.ssh\id_rsa" "/cygdrive/c/Users/test/Downloads" admin@1.2.3.4:/path/to/remote 1> %REPORTLOG% 2> %ERRORLOG%

Any ideas? (thanks!)

This seems to be problem with home directory and non-interactive environment in scheduled jobs in newer Windows version (starting from Server 2008 and Vista?). I find it in few discussions, but with not much info to solve it:

Rsync for Windows cannot run on Task Scheduler

https://superuser.com/questions/368828/rsync-on-windows-xp-works-fine-on-demand-but-hangs-when-run-as-a-scheduled-task

My solution was:

set task to run under user that is proven to be able to finish rsync, set run whenever user are logged on or not, I also set to does not save password,
find location of .ssh folder under this user (in his home directory),
copy .ssh to simplier path to use it in HOME variable (SET HOME=D:\CWRSYNC\HOME),
use following script to run rsync:




    @ECHO OFF
    SETLOCAL
    SET CWRSYNCHOME=D:\CWRSYNC
    SET HOME=D:\CWRSYNC\HOME
    SET CWOLDPATH=%PATH%
    SET PATH=%CWRSYNCHOME%;%PATH%
    rsync.exe -rtvz --delete /cygdrive/b/ user@192.168.1.2:/volume1/NetBackup/ >> D://nas-backup-log.txt

When I experienced this problem on Windows Server 2012 R2, I found SSH.exe was experiencing a permissions error when attempting to create a known_hosts file, despite the task running with an admin's credentials and with highest privileges.

The solution was to point to the user's existing known_hosts file using the UserKnownHostsFile SSH option:

rsync -e "ssh -i sshkey -o UserKnownHostsFile path/to/known_hosts" source dest
