The problem with this DLL is that even newer systems are also affected by this problem.
I had tried Urbackup privately yesterday and was pleasantly pleased with how easy and clear backups are to set up and use.
However, when I tried the trial Hyper-V client today, I had to spend hours looking for a connection issue that had solutions that didn’t work or only worked briefly… and when reading the documentation found by chance IN THE APPLIANCE (also to be tested) it turns out that for months / 1-2 years a wrongly documented and in the web interface specified “Internet Port” 55414 must actually be 55415 - which was also shown wrongly in various Youtube videos.
Now that the backups are running, I wanted to try listing / restoring such a backed up VM specified in the documentation and was running into the error message:
ConvertFrom-Json : Invalid JSON primitive: 2023-08-06.
and encountered the same problem after manually calling the command generated in Powershell:
PS C:\Program Files\UrBackup> Get-ComputerInfo | Select-Object OSName, OSVersion, OsHardwareAbstractionLayer
OsName OsVersion OsHardwareAbstractionLayer
------ --------- --------------------------
Microsoft Windows Server 2016 Datacenter 10.0.14393 10.0.14393.5786
PS C:\Program Files\UrBackup> .\UrBackupClientBackend.exe --cmdline --silent true --required_plugin cryptoplugin.dll --plugin fileservplugin.dll --required_plugin urbackup.dl
l --restore true --restore_cmd get_backupimages_json --virtual_client_name -VmName 'test (10.30.2.211)'
2023-08-06 01:40:04: ERROR: Error loading fsimageplugin
[{
"id": 0,
"letter": "NO RIGHTS",
"time_s": 0,
"time_str": "0"
}
]
PS C:\Program Files\UrBackup>
I am running this cmd in administration mode of powershell and as admin user and use the default connection for it. But also when trying the admin / password credentials it fails with same message.
So I think from
ERROR: Error loading fsimageplugin
that this is the same cause as here written last year.
