我在 Ubuntu 10.10 上运行 VMWare 工作站。我每周都会克隆一系列虚拟机。
我编写了一个 bash 脚本，它在每个虚拟机之间循环，轻轻地挂起它，克隆它，然后尝试恢复它。
问题是，VM 没有恢复，所以我必须手动恢复它们。我试图弄清楚如何修改我编写的脚本以确保虚拟机恢复。我已经包含了脚本和显示错误消息的生成日志文件的示例。

## Purpose: Perform full backups of Virtual Machines
## Running under VMWare Workstation
## Script won't run if the /nas directory doesn't exist
## The /nas directory is a mounted Buffalo Terastation
## Check /etc/fstab if this mountpoint is broken
BACKUPDEST="/nas"
## No need to modify
HOST=`hostname`
DATEFILE=`/bin/date +%G%m%d`
## Run Command to find list of VM names:
## this will only be the name of the vm, no path and no .vmx
VMLIST=`vmrun list | grep '/' | cut -d'/' -f3 | cut -d'.' -f1`
## Initialize Counter variable used to cycle through VMs in VMARRAY variable
COUNTER=1
## Run Command to find list of VM Names and then store them in an Array:
## This will include full pathnames
VMARRAY=( `vmrun list | grep '/'` )
