下面是备份软件报错信息:
错误代码: [72:106] 说明: There are too many existing backup snapshots on virtual machine [虚拟机名称]. Backup snapshots are being cleaned up, however manual intervention may be required to ensure that all snapshots are removed. This may indicate that the storage is unable to keep up with the IO activity of the virtual machine during a backup. Source: cv-server, Process: vsbkp
vsphere中报错信息为:
移除快照,状态:对象已删除或未完全创建。
VMWARE上不能建立太多的快照,太多的快照会严重影响虚拟机的IO性能。
因为VMWARE的快照是保留原VMDK1文件,新的数据写入新的VMDK2中,再建的话又会保留VMDK2文件,新建VMDK3文件,最终虚拟机在VMFS中展现的是VMDK1---VMDK2---VMDK3---....,一次虚拟机的读I/O操作,必然会在多个VMDK文件中顺序查找,这样效率较单个VMDK文件低下很多,尤其是快照数量过多的时候,建议保留1-2个快照即可。。
备份软件每次对VMWARE做一次快照,然后备走,并删除前一个快照。
