I have virtual machines running on VMware ESXi and vCenter. Can I backup these VMs to BMR server?

Yes, you can backup virtual machines running on VMware ESXi host and vCenter server to the BMR server. All you need to do is, add the ESXi host and vCenter server to the BMR server and schedule the backup. Initial backup will be full image backup and subsequent backups can be full or incremental depending on the schedule.

Which versions of VMware ESXi host are supported by IDrive BMR?

Currently IDrive BMR supports ESXi server versions 5.5, 6.0 and 6.5. We do not support free ESXi.

 

Does IDrive BMR support agentless backup for Hyper-V machines?

Since Hyper-V is a Windows machine, backing it up using IDrive BMR allows you to protect all the VMs too. For a successful bare metal restore of the Hyper-V machines, ensure VMs are present locally on the same server during backup.

 

Which operating systems (OS) and file-systems does VMware file-level restore support?

You can enable VMware file-level restore with the following operating systems (OS):

Microsoft Windows Linux BSD, Solaris Mac Disk Types RAID
FAT, FAT32
NTFS
ext2, ext3, ext4
ReiserFS
JFS
XFS
Btrfs
UFS
UFS2
HFS
HFS+
Basic and Dynamic disks are supported Mirrored RAID volumes are supported. Since there are two disks with the same data, both the VMDK images will be mounted for file restore.
Note:
Microsoft Windows - ReFS is not supported.
Linux:
  1. ZFS is not supported.
  2. Linux LVM is supported; however, encrypted LVM volumes are not supported.
BSD, Solaris:
  1. Limited support for variants of UFS, used in the following systems - SunOS, Sunx86, HP-UX, NeXTSTEP, OpenStep

  1. All other types of RAID configuration are not supported.
  2. Striped volumes, and split volumes are not supported.

 

Which operating systems (OS) does BMR VMware backup support?

IDrive BMR is compatible with all operating systems and therefore, supports VM backups running on the VMware machine, irrespective of the OS.

 

I am receiving an error message during VM backup, which says, “An error occurred while taking a snapshot: Failed to quiesce the virtual machine.” What should I do?

You are receiving this error message due to an issue with the configuration of the virtual machine.

The possible causes of this issue include:

  • As per VMware KB 2069952, the Virtual Disk service does not start in the Windows guest operating system on the affected virtual machine.

    If you face this issue,

    1. Log in to the Windows operating system as an administrator.
    2. Click 'Start', type services.msc, and then click 'Enter'.
    3. Right-click the Virtual Disk service and click 'Start'.
  • As per VMware KB 1018194, this issue occurs when the I/O in the virtual machine is high and the quiescing operation is unable to move all the data to the disk, while further I/O is created.

    Follow the resolutions mentioned in this VMware article to successfully complete the VM backup:
    http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1018194

  • When the virtual machine does not have any free space, you may receive this error message. Free up some space on the virtual machine to address this concern.
  • Other VMware KBs related to creating snapshot failure:
    • 2068653 - Quiesced snapshots fail on a Windows Server 2012 virtual machine with Microsoft Exchange 2013
    • 2015181 - Creating a quiesced snapshot of a Windows 2008 virtual machine fails with the error: "Snapshot 0 failed: Failed to quiesce the virtual machine"
    • 1031298 - Cannot take a quiesced snapshot of Windows 2008 R2 virtual machine.

Follow the resolutions mentioned in the respective VMware articles to address these issues and successfully complete the VM backup.
