SQL Server 2012 SP1 CU2 and SQL Server 2014 have built in capability to back up to Windows Azure storage. The SQL Server Backup to Windows Azure tool provides the same functionality for previous versions of SQL Server. It can also be used to provide encryption and compression for your backups.
Using the 3-step wizard, you can specify a rule or set of rules that are applied to any SQL Server backup. One example of a rule could be to redirect all local backups to the specified Windows Azure storage. Another example of a rule would be to use compression or encryption for backups stored in a specific location.
Once you configure the rules, these rules are applied to SQL Server Backup files. If the rule is set to use a Windows Azure storage account, the tool redirects the backups to the specified Windows Azure storage account, but leaves a stub file in the local storage with metadata information to be used during restore.
- Support for backups to Windows Azure Storage for SQL Server versions that do not have the built-in capability. Using Windows Azure storage for your backups has several benefits, such as providing off-site storage for disaster recovery, accessibility regardless of location, etc. For more information, see SQL Server Backup and Restore with Windows Azure.
- Encryption support for SQL Server versions that do not have the built in capability. Currently only SQL Server 2014 has encryption support.
- Compression support for SQL Server versions that do not have the built in capability. Currently, SQL Server 2008 supports compression in Enterprise edition only, but SQL Server 2008 R2 and later, encryption is supported on Enterprise and Standard editions.
SQL Server and Operating Systems Support:
This tool is supported on SQL Server 2005 or later, and Operating System versions: Windows Server 2008 or later for Servers, and Windows 7 or later for Client Operating Systems.
