Also, check the VMware KB article for additional information.Īt this stage the virtual disks or their links are attached to the agent. If it is not created or created zero size it is better to contact VMware support and provide them information about the error. You should be able to see the vss-manifest.zip file.Navigate to the virtual machine datastore: _ESX, then open the problem virtual machine location.Uncheck the "Snapshot the virtual machine's memory" and click OK.Right click on the machine > take snapshot > check the "Quiesce guest file system".Open the vSphere connection to the ESX host.To troubleshoot the issue, run the native quisce snapshot for the problem virtual machine: Under normal circumstances, the vss-manifest.zip file should be created (not zero in size) in the virtual machine snapshot directory and the Acronis agent should parse metadata information from it. If a problem appeared on the metadata collection stage, you will see an error message like: Failed to parse MsExchange VSS writer metadata. For additional information, refer to KB article Acronis vmProtect: Adding vCenter/ESX(i) Host Fails. In order to resolve the problem, please configure proper IP and DNS settings on the Agent agent and make sure that ESX(i)/vCenter are up and running. If the output contains the following line:"Ping request could not find host NAS_name" then the hostname cannot be resolved.In the command prompt type: ping NAS_name.Open the command line: Start > run > cmd.If the output is empty the hostname cannot be resolved.
#Acronis backup for vmware windows
For Windows Agent LAN-free backup is possible, when Agent is connected to the SAN storage with the virtual machines.If VA is connected to the host, vdisks themselves are attached to the VA. In case VA is connected to the vCenter, the linked clones of vdisks are attached. In case of a Virtual Appliance (VA) it happens when it is deployed to the ESX(i) host, to which the datastore with the VM disks is attached.LAN-free backup is activated automatically when available.
For additional information, please refer to this link Acronis agent parses the manifest file and places it in the backup archive. This file is stored in the snapshot directory of the virtual machine. vmNAME-vss_manifestsXXXX.zip) containing the backup components document (BCD) and writer manifests. When the quiesce snapshot is triggered, VMware tools generate a file (e.g. Metadata collection (in application-aware backup) If the process fails on the VMware side, the API request returns error and this causes Acronis Backup for VMware (Acronis vmProtect) backup failure. Read this VMware KB article with detailed description of a VM snapshot. At this point all operations are made by the ESX(i) host. VMware Tools installed inside the guest OS performed the quiescing of the system and applications. Snapshot the virtual machine's memory = off.The agent (Virtual Appliance or Windows Agent) sends an API request to the ESX(i) host to create a snapshot with the following options: When the backup is executed, the agent (Virtual Appliance or Windows Agent) connects to the ESX(i) host or vCenter server to perform the next step. Major steps in ESX(i) Virtual Machine backup:
