     .SYNOPSIS
          Set up a mirrored database
     .DESCRIPTION
          Backs up a database and tlog, copies it to the destination,
          Restores the database on the mirror server, sets up the partner,
          and starts the mirror.
     .PARAMETER  database
          The name of the database to be mirrored
     .PARAMETER  SourceServer
          The name of the primary server
     .PARAMETER  SourcePath
          Local Path for the backup
     .PARAMETER  DestServer
          The name of mirror server
     .PARAMETER  DestPath
          Local path for restore file
     .EXAMPLE
          PS C:\> Invoke-Mirror -database 'string value' 1
                    -SourceServer 'string\string' -SourcePath 'string' `
                    -DestServer 'string\string' -DestPath 'string'

wordpress 内容备份镜像站点建立方法及注意事项
作为虾米级站长一枚,实则是不懂代码的菜鸟,由于自己的站点是小水管主机,而且稳定性也难以保障,在很多访客的建议下,也想建立一个内容镜像站点,以实现当主站的主机维护时,能够有一个备用站点让访客访问。 最先我是想能够有一个共用的数据库可以给两个站点一起使用,但百度查了资料后,发现这对于虚拟主机建站来说好像不适用。
