NetVault Plug-in for VMware 12.3.3.5 - Release Notes

Added support for VMware 7.0.3.

DNVMWARE-2368

When restoring data to an alternate datastore, the plug-in does not verify whether the datastore is available. Verify that the datastore is valid and has sufficient disk space to accommodate the virtual machine.

DNVMWARE-18 (1714)

The configuration setting [Custom:MountOperationTimeoutSecs], which is stored in the vmware.cfg file, determines how long the plug-in process waits for the mount daemon to respond to a request. The default value is set to 600 seconds during a fresh install and 300 seconds during an upgrade. If the mount daemon is unable to complete a request within the specified interval, the virtual machine is left in a mounted state.

If you have many backups running simultaneously or your server is running under heavy load, modify the value for the [Custom:MountOperationTimeoutSecs] setting to avoid this issue.

DNVMWARE-505 (3131)

Virtual Disk Development Kit (VDDK) does not support non-UTF8 locales. On Linux-based clients that use non-UTF8 locales, the plug-in reports the error “Child Process died unexpectedly” and exits abnormally.

DNVMWARE-584 (3340)

You cannot back up virtual machine templates using the Plug‑in for VMware.

Workaround: Convert the template to a virtual machine.

DNVMWARE-713 (13728, VMW-202)

The file-level indexing process does not generate indexes for symlinks.

DNVMWARE-977 (21793)

The file-level indexing process does not treat hard links in any special way and generates index entries for them as if they are separate entities. When you restore a saveset that includes a hard link, the plug-in stops responding.

DNVMWARE-978 (21794)

When restoring NTFS sparse files, if the actual allocated size of a data run is smaller than the total size of the data run, the restored file might be corrupted.

DNVMWARE-1456 (29043)

Backups that have Active Block Mapping (ABM) enabled might stop working when memory is exceeded.

DNVMWARE-1584

The plug-in is unable to restore a virtual machine protected by VMware vSphere Fault Tolerance (vSphere FT) to an alternate VMware vCenter Server.

DNVMWARE-1691 (32398)

Backing up a virtual machine succeeds if the Virtual Machine Disk (VMDK) fails to open and the Exclude data disks option is selected.

DNVMWARE-1696

If the inventory view is toggled, the selection set is grayed out on the Edit Set and Clone Set operations.

DNVMWARE-1900

ATTENTION: Aborting a restore to the original location deletes the original virtual machine. This issue may result in data loss.

Workaround: Before you begin a restore to the original location, clone the original virtual machine.

DNVMWARE-1906

Plug‑in for VMware does not work on CentOS 6.x and RHEL 6.x, because those operating systems do not include glibc-2.14.

Workarounds: Upgrade NetVault Backup Client server to CentOS 7.x or RHEL 7.x, or Downgrade the plug-in to Plug‑in for VMware 12.3.0.

NV-1086

When backing up a powered on virtual machine through a VMware vCenter Server, the plug-in may fail to back up the “.nvram”, “.vmx”, and “.log” files. For more information, see http://kb.vmware.com/kb/1019286.

When a snapshot is created on a virtual machine that uses thin-provisioned disks, VMware vSphere (the client and the underlying disk library) identifies the disk as thick. For more information, see http://kb.vmware.com/kb/1020137.

At the time of enabling CBT for a virtual machine, no snapshots must exist on it. For more information, see http://kb.vmware.com/kb/1033816.

If an ESXi 5.x host is managed by a vCenter Server, the virtual machines should not be restored when connected directly to the ESXi host. This restriction is due to a feature introduced in vSphere 5. For more information, see http://www.vmware.com/support/developer/vddk/VDDK-500-ReleaseNotes.html#knownissues.

To prevent the migration of a virtual machine while its disks are being accessed for a backup or restore, the plug-in uses VDDK APIs to lock and unlock a virtual machine. This functionality is disabled by default. To enable it, see the user's guide for the plug-in. Currently, the locking functionality has the following known issues:

On a Windows 2012 virtual machine, data corruption may occur during or after a network copy operation. For more information, see http://kb.vmware.com/kb/2058692.
