Zálohování Windows Azure Packu: Weby

Platí pro: Windows Azure Pack

Zálohování Windows Sady Azure Pack: Weby zahrnují tři hlavní komponenty: řadič webů, SQL Server a souborový server. Níže najdete odkazy na příslušné oddíly.

A. Backup kontroleru webů

B. SQL Server Backup

C. Backup souborového serveru

A. Backup kontroleru webů

K zálohování kontroleru webů můžete použít skriptBackup.ps1 PowerShellu uvedený v této části. Tento skript vyvolá zapisovač stínové služby svazku (VSS) Windows k provedení zálohování.

Zkopírujte skript Backup.ps1 na řadič webů a spusťte následující příkaz s oprávněními správce:

net use /Y $backupLocation /user:$backupMachineAdmin $backupMachinePassword  
.\Backup.ps1 $backupLocation $encryptionKey  

Skript Backup.ps1 následuje.

B. SQL Server Backup

Při zálohování SQL Server musíte zálohovat databázi hostingu, databázi měření prostředků a hlavní databázi. Vzhledem k tomu, že se prostředí SQL každého uživatele liší, nemůže žádný skript vyhovovat požadavkům každého uživatele. Následující ukázkový skript je k dispozici pouze pro ilustrativní účely a není podporován. Skript, který vytvoříte, musí být spuštěn s oprávněními správce.

Ukázkový skript SQL Server Backup

param ([string] $backupUser = "Administrator", $backupPassword, $sqlServer, $sqlUser = "sa", $sqlPassword, $backupLocation = "\\backupMachine\c$\Backup")  
sqlcmd -S $sqlServer -U $sqlUser -P $sqlPassword -Q "BACKUP DATABASE [Hosting] TO DISK='C:\HostingOfflineFeed\Hosting.bak'"  
sqlcmd -S $sqlServer -U $sqlUser -P $sqlPassword -Q "BACKUP DATABASE [ResourceMetering] TO DISK='C:\HostingOfflineFeed\ResourceMetering.bak'"  
sqlcmd -S $sqlServer -U $sqlUser -P $sqlPassword -Q "BACKUP DATABASE [master] TO DISK='C:\HostingOfflineFeed\master.bak'"  
net use $backupLocation /user:$backupUser $backupPassword  
xcopy /Y /q C:\HostingOfflineFeed\Hosting.bak $backupLocation\  
xcopy /Y /q C:\HostingOfflineFeed\ResourceMetering.bak $backupLocation\  
xcopy /Y /q C:\HostingOfflineFeed\master.bak $backupLocation\  
del C:\HostingOfflineFeed\Hosting.bak  
del C:\HostingOfflineFeed\ResourceMetering.bak  
del C:\HostingOfflineFeed\master.bak  

C. Backup souborového serveru

Při zálohování souborového serveru je nutné zálohovat sdílenou složku WebSites, seznamy ACL pro dříve uvedenou složku a kvóty souborového serveru Resource Manager (FSRM) pro sdílenou složku WebSites.

Vzhledem k tomu, že se prostředí souborového serveru každého uživatele liší, nemůže žádný skript vyhovovat požadavkům každého uživatele. Následující ukázkové skripty jsou k dispozici pouze pro ilustrativní účely a nejsou podporovány. Skripty, které vytvoříte, se musí spouštět s oprávněními správce.

Ukázkový souborový server Backup skript

param ([string] $backupUser = "Administrator", $backupPassword, $websiteFolder = "C:\websites", $backupLocation = "\\backupmachine\c$\backup" )
net use $backupLocation /user:$backupUser $backupPassword
xcopy /Y /q /E $websiteFolder $backupLocation\ 

Ukázkový skript Backup dat kvóty FSRM

param ([string] $backupUser = "Administrator", $backupPassword, $backupLocation = "\\machine\c$\backup")
net use \\$backupLocation /user:$backupUser $backupPassword
dirquota template export /File:C:\templates.xml
xcopy /Y /q C:\templates.xml $backupLocation\
net stop srmReports
net stop srmSvc
net stop quota
net stop Datascrn
robocopy "C:\System Volume Information\SRM" $backupLocation\SRM /E /ZB /R:3 /W:5
net start Datascrn
net start quota
net start srmSvc
net start srmReports
