Veeam对于备份虚拟机而言,挺不错的,而且还有免费版,目前最新的是Veeam Backup Free Edition 9.5。
- 免费版只能使用VeeamZip进行完整备份,不能设置备份计划(Backup Job)。
- 收费版可以设置备份计划,会自动进行增量备份,也可以在计划内设置完整备份的时间。
因此,免费版每天的备份量是很大的,有条件的可以考虑使用收费版。
言归正传,我们现在来设置一下,让免费版也有计划任务。
免费版在程序界面是设置不了计划的,谁让它是免费的呢,但是我们可以借助PowerShell和PS脚本,手动来做个包含批量备份的计划任务。

VMNames:后面跟虚拟机的名字,在vCenter、ESXi上显示的名字
HostName:vCenter服务器的IP或域名,我只在vCenter上面试过,因为涉及到多台服务器。如果没有vCenter并且要备份多台服务器里的虚拟机,不清楚能不能像vmnames这样做一个foreach。
Directory:目录,支持网络路径,即\192.168.x.x\Folder
CompressionLevel :默认是4,数字越大压缩率越高,相关文档没介绍这个值可以最大多少
Retention:这个没有测过,备份保存天数。In1Week是保存一周。不清楚会不会自动删除旧备份。如果不会删,看我之前的一个帖子,手动写个清理脚本也可以。
EMAIL那部分就是SMTP地址、发件人、收件人,最后两行我注释掉了,如果需要发送邮件,去掉最后两行的注释就可以。
然后保存这个脚本,可以放到C盘,起名VeeamZip.ps1
PowerShell路径:C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe
计划任务里,设置powershell的路径,参数设置"C:\VeeamZip.ps1"
OK,设置个任务它就可以自动备份了,添加完后可以手动执行一下看看效果。
以上脚本参考外国网站,具体哪个网站我没记,搜索一下应该可以搜索到原文的。
