Quiesced backup of an ESX 4 or 4.1 VM with multiple disks fails with Error 2800
설명
When performing a quiesced backup of an ESX 4 or 4.1 VM with multiple disks, and the disks have the same name, backups may fail with the error message "Backup failed: Error: 2800 - filter file contains the wrong number of blocks"
원인
This occurs because the datastore for the first disk is used for all snapshots. This will cause the filter file to have the same name and datastore ID leaving only one filter file for the multiple VMDK's.
해결 방안
In order to successfully backup these VMs, rename the disks to avoid duplicate names.
