Test-Connection fails

[rawtaz]

I've followed the installation instructions and am running stuff as an administrator, but noticed that the scheduled task didn't start properly. Turned out that it's due to this (the following is from a manual run in an administrator PS shell, to see the errors):

WARNING: Errors found! Error Log: C:\restic\logs\20200216T2334197164.err.txt
Something went wrong. Sleeping for 15 min and then retrying...

I'm using the following config (it's for a repository on a rest-server):

# restic backup repository configuration
$Env:AWS_ACCESS_KEY_ID=''
$Env:AWS_SECRET_ACCESS_KEY=''
$Env:RESTIC_REPOSITORY='rest:https://user:[email protected]/user'
$Env:RESTIC_PASSWORD='password'

I did see the comment in https://github.com/kmwoley/restic-windows-backup/blob/master/backup.ps1#L216 and am guessing it's the string parsing that doesn't work properly.

Is this something you could fix easily or is it a more long-term issue? I realize that a fix should preferrably be backend-agnostic, which isn't very straight-forward.

For now I'll just hardcoded the proper hostname into that variable.

I think it’s an easy one to address. I’ll look into it this week.

I have the same error using an SFTP connection.
I would be glad if you could look into this.

[flicksolutions]

As a quickfix:
I just set the variable $repository_host to the IP-Adress/Hostname of my SFTP-Server.
So i just replaced Line 220 of backup.ps1 to the following:

    $repository_host = <MY HOSTNAME/IP>

I'll get a fix for this pretty shortly; the internet connectivity check didn't handle all repo types. It will in the next release. Thanks for letting me know!
