So you're having problems with free backup software of your free ESXi and want free help with it. Got it.
Has this worked at all ever or no? What is the size of the VM you're trying to protect?
If the backup destination is set on local hard drive it works perfectly, i have tried to backup a 10 GB VM and it's ok, the problem is when i select the NAS as backup destination.
This NAS is presented to the ESXi host? If so, can you create any files whatsoever from the ESXi host on this export?
The NAS is not registered as a datastore to the ESXi host, but inside the VM (Win server 2012) where is installed the backup software i can see the nas as a network NFS share, so in backup configuration I set as destination, the path to the NAS.
NAS is a dlink dns 320L
Don't know anything about this application or how it works, but it sounds like a problem with your NFS export configuration. You're better off seeing if you can get help from the vendor...for free.
the error is due to overly eager VDDK checks before creating large virtual disks. They sometimes result in false positives.
You may try to:
- change file system on the NAS side
- use a newer version of VDDK
I'm not very familiar with Thinware vBackup, but in my environment I get good results with VDDK 5.5.5 and 6.5.2. I haven't had the time to test newer releases. VDDK is under rapid development which means you really have to test thoroughly.
Let us know if you managed to resolve the issue!
