After installing VMware Data Recovery I scheduled a fresh job to make a backup of my VM’s in the datacenter. The first 8 VM’s backuped successful, but the VM’s with a iSCSI target (Exchange, SQL) crashing after creating virtual machine snapshot. I received this error:
Creating a quiesced snapshot failed because the created snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine.

To install vcb follow the instructions on this link.
The first time I came in contact with vcb I created some batch files to make vcb snapshots. I encountered all kind of problems. Snapshots that vcb didn’t remove. unexpected errors no vss support and some more issues.
To overcome some of these problems I created a vbs script vcbBackup.vbs. The full howto is comming soon for now only the code. Read more…
Mostly you have on a terminal (citrix) server just 1 volume. With Windows 2008 it’s default not possible to create a SSB to the source volume.
You can change this do doing the following:
Create a new registry entry with the following information:
Key: HKLM\SYSTEM\CurrentControlSet\Services\wbengine\SystemStateBackup\AllowSSBToAnyVolume
Type: DWORD
Value: 1
A value of 0 prevents the storing of system state backup on a source volume. A value of 1 allows the storing of system state backup on a source volume.
However, there are known issues with storing a system state backup on a source volume:
- Backups can fail. The backup can be modified during the backup process, which might cause the backup to fail.
- It causes an inefficient use of target space. Twice the amount of space is necessary for a backup than for the original data. The volume must allocate twice the amount of space for the shadow copy process.
Just seeing that I can use VMware Data Recovery (VDR) without connecting vCenter by vSphere client, I only connect to the ESX host. You need only install the VMware Data Recovery Plugin into your VMware vSphere Client and you can manage your backups.
Little note: vCenter must be online!

Indien je tape’s goed zijn genummerd en weet dat je ongeveer een tape (fabrieks verhaal) ongeveer 20x mag gebruiken om de kwaliteit van de tape te waarborgen kan je er voor kiezen om de Expiration Date kan omzijlen.
Dit kan door de volgende register instelling toe te passen:
HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\BrightStor ARCServe Backup\Base\Task\Backup\
Verander DWORD: ResetTapeExpirationDate
Geef deze een waarde 1
Vanaf nu zal er niet meer worden gekeken naar de Expiration date. Houdt het beheer dus zelf goed in de gaten.
Wat mij opgevallen is aan de nieuwe versie van Symantec Backup Exec, versie 12, er bij installatie maar
1 Media set is welke op alle tapes wordt toegepast die gebruikt worden door deze server, ik heb
binnen het pakket nog geen optie kunnen vinden welke het gebruiken van Media Sets uitschakelt.

We created a VCB bcakup script to simplify the vcb backup check out the article here
1. Install an appropriate version of Windows for the VCB Proxy. For more information, see the Virtual Machine Backup Guide.
Note: Setup your 3rd party backup software and hardware according to your vendor documentation
2. Download VCB at: http://www.vmware.com/products/vi/consolidated_backup.html
3. Verify that Automount is disabled.
- Click Start > Run.
- Type diskpart and press Enter.
- Type automount and press Enter.
- If Automount is enabled, type automount disable to turn off the feature. This prevents resignaturing of your VMFS LUNs when are presented to the VCB Proxy machine.
- Close the diskpart command prompt.
