这个相同的代码已经在 3 个服务器中使用过,只有其中一个会默默地无法移动项目(它仍然会删除它们,但它们不会出现在共享中)。
Azure-MapShare.ps1
param (
[string]$DriveLetter,
[string]$StorageLocation,
[string]$StorageKey,
[string]$StorageUser
)
if (!(Test-Path "${DriveLetter}:"))
{
cmd.exe /c "net use ${DriveLetter}: ${StorageLocation} /u:${StorageUser} ""${StorageKey}"""
}
获取排除天数.ps1
param (
[datetime]$startDate,
[int]$daysBack
)
$date = $startDate
$endDate = (Get-Date).AddDays(-$daysBack)
$allDays =
do {
"*"+$date.ToString("yyyyMMdd")+"*"
$date = $date.AddDays(-1)
} until ($date -lt $endDate)
return $allDays
迁移文件.ps1
param(
[string]$Source,
[string]$Filter,
[string]$Destination,
[switch]$Remove=$False
)
#Test if source path exist
if((Test-Path -Path $Source.trim()) -ne $True) {
throw 'Source did not exist'
}
#Test if destination path exist
if ((Test-Path -Path $Destination.trim()) -ne $True) {
throw 'Destination did not exist'
}
#Test if no files in source
if((Get-ChildItem -Path $Source).Length -eq 0) {
throw 'No files at source'
}
if($Remove)
{
#Move-Item removes the source files
Move-Item -Path $Source -Filter $Filter -Destination $Destination -Force
} else {
#Copy-Item keeps a local copy
Copy-Item -Path $Source -Filter $Filter -Destination $Destination -Force
}
return $True
作业步骤是在所有 3 台服务器上键入“PowerShell”,并包含相同的代码:
#Create mapping if missing
D:\Scripts\Azure-MapShare.ps1 -DriveLetter 'M' -StorageKey "[AzureStorageKey]" -StorageLocation "[AzureStorageAccountLocation]\backup" -StorageUser "[AzureStorageUser]"
#Copy files to Archive
D:\Scripts\Migrate-Files.ps1 -Source "D:\Databases\Backup\*.bak" -Destination "D:\Databases\BackupArchive"
#Get date range to exclude
$exclusion = D:\Scripts\Get-Exclusion-Days.ps1 -startDate Get-Date -DaysBack 7
#Remove items that are not included in exclusion range
Remove-Item -Path "D:\Databases\BackupArchive\*.bak" -exclude $exclusion
#Move files to storage account. They will be destroyed
D:\Scripts\Migrate-Files.ps1 -Source "D:\Databases\Backup\*.bak" -Destination "M:\" -Remove
#Remove remote backups that are not from todays backup
Remove-Item -Path "M:\*.bak" -exclude $exclusion
如果我使用 SQL 运行作业步骤,则文件将被删除,但不会出现在存储帐户中。如果我手动运行此代码块,它们会被移动。
当我在服务器上启动 PowerShell 时,我收到一条错误消息:“尝试对 'FileSystem' 提供程序执行 InitializeDefaultDrives 操作失败。” 但是,这不会真正影响其余操作(例如,将备份文件复制到 BackupArchive 文件夹)。
我应该提到,copy-item 也无法复制到共享,但成功复制到 /BackupArchive 文件夹
