SQL Server自动定时备份还原到另一台服务器

cgsthtm2025-10-11 12:38

10.101.10.252 服务器是生产数据库服务器，10.80.189.43 服务器是开发测试服务器，想要将 10.101.10.252 上的生产库每天早上6点备份还原到 10.80.189.43 上，操作如下：

首先在 10.101.10.252 上面创建一个 SQL Server 代理作业，以定时备份数据库，如下：

将 10.101.10.252 上创建一个共享文件夹，以便 10.80.189.43 拷贝备份的数据库文件，如下：

添加 SQL_Worker 共享权限，如下：

在 10.80.189.43 上面映射网络驱动器，如下：

在 10.80.189.43 上面创建一个 powershell 脚本，用以从共享文件夹拷贝备份文件，如下：

powershell 复制代码 
# net use F: \\10.101.10.252\Backup /user:10.101.10.252\SQL_Worker "Anfeng@2025" /persistent:no | Out-Null
$SharePath = "\\10.101.10.252\Backup"
$LocalPath = "E:\Program Files\Microsoft SQL Server\MSSQL16.MSSQLSERVER\MSSQL\Backup"
$DBName = "LGJL"
$DBName1 = "LGJLLOG"

$DateStr = Get-Date -Format "yyyyMMdd"

$FilePattern = "${DBName}_${DateStr}_*.bak"
$FilePattern1 = "${DBName1}_${DateStr}_*.bak"

$File = Get-ChildItem -Path $SharePath -Filter $FilePattern | Select-Object -First 1
$File1 = Get-ChildItem -Path $SharePath -Filter $FilePattern1 | Select-Object -First 1

if ($File) {
    $DestPath = Join-Path -Path $LocalPath -ChildPath $File.Name
    
    try {
        Copy-Item -Path $File.FullName -Destination $DestPath -Force
        Write-Output "$(Get-Date) - success copy file: $($File.Name)"
    }
    catch {
        Write-Error "$(Get-Date) - failed copy file: $_"
        exit 1
    }
}
else {
    Write-Error "$(Get-Date) - can't find file: $FilePattern"
    exit 1
}

if ($File1) {
    $DestPath1 = Join-Path -Path $LocalPath -ChildPath $File1.Name
    
    try {
        Copy-Item -Path $File1.FullName -Destination $DestPath1 -Force
        Write-Output "$(Get-Date) - success copy file: $($File1.Name)"
    }
    catch {
        Write-Error "$(Get-Date) - failed copy file: $_"
        exit 1
    }
}
else {
    Write-Error "$(Get-Date) - can't find file: $FilePattern1"
    exit 1
}

在 10.80.189.43 上面的任务计划程序中创建任务，如下：




在 10.80.189.43 上面创建一个 SQL Server 代理作业，以自动还原备份的数据库文件，如下：
