NBU备份Vmware

错误ID：4292

官方文档解释：

For VMware Change Block Tracking support, you must ensure that no snapshots exist on a virtual machine when NetBackup enables Change Block Tracking on that VM. NetBackup enables CBT on a VM if Enable block-level incremental backup is selected in the backup policy and CBT is not enabled already on the VM. Note: If a snapshot exists on the VM when NetBackup enables CBT, the backup job fails and reports error 4292, "snapshot creation failed."（备份虚拟机存在快照）
