In my environment, it appears I am 3 out of 5

- The VM is Thin provisioned (Thick provisioned virtual disks on the host server (may not cause error if disks have minimal free space))
- I am forced to use None (Compression Level is set to None on the job in vBackup (only option with Standard Edition))
- I have an iSCSI connection to the target- not sure how that compares to the speed of USB 2.0 (Backup target is on USB 2.0 (or slower) external hard drive (results in slower write speeds))
- The Backup target is on a Network Share (Backup target is on network share (results in slower write speeds))
- Backup Server is a 64-bit Window Server 2012 (Backup server is running 32-bit Windows)

So is Thinware recommending I install the software on the same server as where I store the backup VMs?

This should have been clear in the beginning of the installation manuals before I get a separate server to do all my Sync-ing and backing up and before I requested the hardware ID/licensing for it.

Similar issue here:
Thinware(R) vBackup(R)
Version: 4.0.0.2708 (Version 4.0)
...
[NFC ERROR] NfcNetTcpRead: bRead: -1
[NFC ERROR] NfcNet_Recv: requested 262016, recevied only 131072 bytes
[NFC ERROR] NfcFile_RecvMessage: data recv failed. retval = 3, expected 262016
[NFC ERROR] NFC_NETWORK_ERROR
Failed to convert disk: Operation completes asynchronously (0x300004650).

E Unable to complete backup. Unable to verify successful transfer of virtual machine virtual disk file Z:\ibiza\WebServers-Internal\140609_144555\WebServers-Internal.vmdk.
----------

I tried to increase the NFC timeout in my ESXI server but nothing changed. I'm with standard license, no compression and remote (ethernet) backup disc.

Thinware support please find a solution or enable again basic compression for standard license.

What we are saying then is the standard version of this product doesn't work. I have only had standard licenses as I wanted to test the product with a view to purchasing, in a way I'm glad I did, I have to say I'm not filled with confidence.
I was on the verge of purchasing until I had to install version 4, I now have no backup cover for some VM's. I have to ask myself should I be looking elsewhere?

We are sorry you are having problems.

The Standard Edition of vBackup does work.

If you are getting an error similar to the following ALL you need to do is use faster storage for your backups.

[NFC ERROR] NfcNetTcpRead: bRead: -1
[NFC ERROR] NfcNet_Recv: requested 261720, recevied only 229376 bytes
[NFC ERROR] NfcFile_RecvMessage: data recv failed. retval = 3, expected 261720
[NFC ERROR] NFC_NETWORK_ERROR
Failed to convert disk: Operation completes asynchronously (0x300004650).

This error is reported by VMware VDDK and typically points to slow write performance on your backup storage.

An EASY way to improve write speed on your backup storage is to use compression, but yes, this requires either vBackup Advanced or Professional Edition AND this does not always do it. In some cases the write speed, even with compression, is not fast enough.

Another way to improve write speed is to use locally attached drives for your backup storage. This can be in the form of internal or external USB drives directly attached to your backup server. Using faster RPM drives and interfaces will always improve performance (e.g. 7200 RPM is better than 5400 RPM and USB 3.0 is better than USB 2.0).

The following forum post might help as well.

The pre 4 standard edition worked when backing up to a QNAP connected to the backup machine and machines being backed up on a Gig switch.

Version 4 standard edition fails. If I buy a professional or advanced licence and use compression will Gig switch to the QNAP be fast enough ?

Thanks
