VMware: Snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine

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.

    Ok, so please correct me if I’m wrong but not only does vmware VDR not only support VSS for applications but you also need to remove it from the guests in order to get reliable backups?

    My apologies, I meant “not only does VDR NOT support VSS for applications”

    Unfortunately, Volume Shadow Copy Services Support is ALREADY disabled in my VMTools and I’m still getting this exact error!

    This is not a solution to the problem. It only makes sure that the quiescing operation is not performed during snapshot.

    From VMWare:
    Quiescing a file system is a process of bringing the on-disk data of a physical or virtual computer into a state suitable for backups. This process might include such operations as flushing dirty buffers from the operating systems in-memory cache to disk, or other higher-level application-specific tasks.
