VMware backups for windows 2003 vm clients fails with statsus code 156 .

Error Message

In the bpfis logs we see the below error message .

" Cannot create a quiesced snapshot because the create snapshot operation exceeded the time limit for holding off I/O in the frozen virtual machine"


The issue is with application based quiescing .

App based quiescing is not supported in windows 2003 .

Also quiescing is done by vmware and not by netbackup .

Netbackup just back up the VM *after* it is quiesced


The issue is can resolved by disabling the quiescing .

For more information, refer to VMWare KB Article 1007696.
