VMware Virtual Disk Manager: VMware Virtual Disk Manager - build 2248791
VMware Virtual Disk Manager response for Hard disk 1: [datastore1] Cacti/Cacti.vmdk:
SSL_VerifyCbHelper: Certificate verification is disabled, so connection will proceed despite the error
[NFC ERROR] NfcNetTcpRead: bRead: -1
[NFC ERROR] NfcNet_Recv: requested 261648, recevied only 196608 bytes
[NFC ERROR] NfcFile_RecvMessage: data recv failed. retval = 3, expected 261648
[NFC ERROR] NFC_NETWORK_ERROR
Failed to convert disk: Operation completes asynchronously (0x300004650).
i Tips:
- Even though an SSL certificate error was encountered, certificate verification is disabled causing the error to be ignored. To correct certificate verification error(s), install a valid CA-signed certificate on your host server and install a valid CA-signed root certificate on your vBackup server.
- The 'NFC read' error is caused by a limitation in VMware Virtual Disk Development Kit (VDDK) and how VDDK handles reading and writing thick-provisioned virtual disks. This then effects host servers licensed with Thinware vBackup Standard Edition (and Advanced and Professional Editions when a backup job's compression level setting is set to none). To resolve this, for Thinware vBackup Advanced and Professional Editions, simply set the backup job's compression level to basic or advanced. For Thinware vBackup Standard Edition, the virtual machine's virtual disk(s) must be converted to thin-provisioned (backup of thick-provisioned virtual disks is not supported with Thinware vBackup Standard Edition).
Password file successfully deleted, but was left unencrypted during job execution (due to above error).
