如何将计划的 XenServer VM 备份保存到外部驱动器

如何将计划的 XenServer VM 备份保存到外部驱动器

服务器:XenServer 7.1

管理:思杰中心

目标:将计划快照保存到通过 USB 连接到服务器的外部驱动器

问题:服务器将外部驱动器识别为可移动存储库,但我无法找到将其设置为快照的默认位置。

这是我创建的代码。它每天凌晨 4 点通过 SUDO 的 cron 运行

#!/bin/bash

datum=`date +%Y%b%d`
xsname=`hostname`
uuidfile=/root/xenuuids.txt
mountpoint=/var/removable
backuppath=$mountpoint/vms/$xsname/$datum

if [ ! -d $mountpoint/vms ]; then
 mount /dev/sdb1 $mountpoint
 mkdir $mountpoint/vms
fi

if [ ! -d $mountpoint/vms ]; then
 echo "No mountpoint found. Please check!"
 exit 0
fi

mkdir -p $backuppath
if [ ! -d $backuppath ]; then
 echo "No backup path found. Please check!"
 exit 0
fi

xe vm-list is-control-domain=false is-a-snapshot=false | grep uuid | cut -d":" -f2 > $uuidfile

if [ ! -f $uuidfile ]; then
 echo "No UUID file found. Please check!"
 exit 0
fi

while read VMUUID
 do
  VMNAME=`xe vm-list uuid=$VMUUID | grep name-label | cut -d":" -f2 | sed 's/^ *//g'`
  SNAPUUID=`xe vm-snapshot uuid=$VMUUID new-name-label="SNAPSHOT-$VMNAME-$datum"` 

  xe template-param-set is-a-template=false ha-always-run=false uuid=$SNAPUUID
  xe vm-export vm=$SNAPUUID filename=$backuppath/SNAPSHOT-$VMNAME-$datum.xva
  xe vm-uninstall uuid=$SNAPUUID force=true

done <$uuidfile

umount $mountpoint

exit

享受! :)
