SQL Backup to Azure6 |
Problem
As DBAs, we don't only have the responsibility to backup databases on regular basis,
but also to ensure that backup drives and tapes are secure so databases can be
restored when needed. I heard that SQL Server 2012 supports backups and restores
using a Windows Azure Blob Storage account. How does this work and how do I get
started?

29. Versiones de SQL Server que no lo soportan
¿Qué hacer?
 SQL Backup to Azure Tool
 Antes de SQL 2012 SP1
 Configuración similar
 Mismos datos
 Se basa en reglas:
 Carpetas
 Tipos de archivo
 Permite:
 Compresión
 Distintos tipos de encripción
 Está en:

35. Mejores prácticas
 Usar nombres únicos para identificar cada backup
fecha/hora/bd/servidor
 Definir el acceso al contenedor como private
 Utilizar la misma región para mejorar rendimiento y manejar
costos (*)
 Monitorear constantemente el fallo/éxito de las operaciones si
se automatiza
 Usar la opción WITH COMPRESSION para minimizar los
costos de storage y el tiempo
 Usar encripción (*)
 Hacer pruebas de tiempo de respaldo y recuperación
 Revisar los SLA’s de Azure(http://www.microsoft.com/en-
us/download/details.aspx?id=6656)

41. Tail-log backup (respaldo del log)
 A tail-log backup is a transaction log backup
that includes the portion of the log that
has not previously been backed up (known
as the active portion of the log). A tail-log
backup does not truncate the log and is
generally used when the data files for a
database have become inaccessible but the
log file is undamaged.

43. Respaldo FULL (incluyendo BD’s del sistema)
 This includes both user databases
and msdb system database. The script filters
out tempdb and model system databases.

45. Full Database Backup for MASTER and MSDB (SYSTEM
DATABASES) On All the Instances of SQL Server
The following script can be used to back up master and msdb databases on all the instances
of SQL Server installed on the computer.
import-module sqlps
$storageAccount = "mystorageaccount"
$blobContainer = "privatecontainertest" $backupUrlContainer =
"https://$storageAccount.blob.core.windows.net/$blobContainer/"
$credentialName = "mybackupToUrl"
$sysDbs = "master", "msdb"
#cd to computer level cd sqlserver:sqlCOMPUTERNAME
$instances = Get-childitem
foreach ($instance in $instances) {
foreach ($s in $sysdbs) {
Backup-SqlDatabase -Database $s -path
"sqlserver:sql$($instance.name)" -BackupContainer $backupUrlContainer -SqlCredential
$credentialName - Compression On
}

46. Ejemplo de script Powershell
$db = $svr.Databases['AdventureWorks']
$dbname = $db.Name
$dt = get-date -format yyyyMMddHHmmss
$dbbk = new-object
('Microsoft.SqlServer.Management.Smo.Backup')
$dbbk.Action = 'Database'
$dbbk.BackupSetDescription = "Full backup of " + $dbname
$dbbk.BackupSetName = $dbname + " Backup"
$dbbk.Database = $dbname
$dbbk.MediaDescription = "Disk"
$dbbk.Devices.AddDevice($bdir + "" + $dbname + "_db_" + $dt
+ ".bak", 'File')
$dbbk.SqlBackup($svr)

 $svnm = $svr.Name
 $db = $svr.Databases['AdventureWorks']
 $dbname = $db.Name
 $dt = get-date -format yyyyMMddHHmmss
 $bfil = "$bdir$($dbname)_db_$($dt).bak"
 Backup-SqlDatabase -ServerInstance $svnm -
Database $dbname -BackupFile $bfil
