Complete Data Security and Privacy with Built-In Encryption

Oracle Secure Backup provides the ability to encrypt backups to ensure data
security and privacy.While most Storage
Cloud vendors provide robust security to ensure that only authorized users can
access data, Oracle Secure Backup’s ability to encrypt data at its source

Network bandwidth consumption and the time required to complete backups can
be another major concern while backing up databases to the Cloud, over the public
Internet. The Oracle Secure Backup Cloud module features a rich set of capabilities
to intelligently minimize the volume of backup data and also to compress backups.

Oracle Secure Backup is tightly integrated with the Oracle Database engine, Oracle Secure Backup can identify unused space (blocks) within the database and skip backing it up. Since database administrators typically allocate more space than they actually use, to provide headroom for future growth, this can lead to a substantial reduction in both backup size and time.

Additionally, starting with Oracle Database 11g,
Oracle Secure Backup can also eliminate committed undo data from backup by
identifying and backing up only the “active” undo data (i.e. undo data related to
transactions in progress at the time of backup). Database undo sizes typically range
from 10 to 100s of GB and this optimization can also lead to significant
improvements in backup performance.
It is important to note that both unused space and undo data backup optimization
are unique features of Oracle Secure Backup and are not available with any other
backup product.



With Oracle Secure Backup Cloud module, users can also utilize RMAN’s rich
compression capabilities. This includes the Oracle Database 11g Fast Compressed
Backup feature, which normally requires the Advanced Compression option.cost. Compression typically results in a 50% reduction in backup size.

Cloud Computing &Oracle

• Oracle software can now be licensed for the Cloud
– Amazon EC2 supported today
• Database, Middleware, Grid Control
– EE: Each virtual core counted as a physical x86 core (EE)
– SE/SE1 license based on the EC2 instance size
• 0-4 virtual cores = 1 processor (socket)
• >4 virtual cores = each 4 virtual core counted as a
processor (socket)
• Oracle Enterprise Linux
– Each EC2 instance is counted as a “System”
• Can buy new licenses or use existing ones
• Customers with ULAs can use EC2 without any
additional license

Deploying Oracle Software in the Cloud
--------------------------------------
• Pre-configured virtual machine images (AMIs) available for EC2
• Consists of Oracle Enterprise Linux + Oracle DB + APEX
– No RAC support currently (EC2 does not support clusters)
• Fully configured hardware and Oracle environment in less than 30 minutes

Oracle Secure Backup Cloud
--------------------------
Using the newly introduced Oracle Secure Backup
Cloud module, it is now possible to send local disk backups directly to the Storage
Cloud for offsite storage purposes. The Cloud backup module is a part of the
Oracle Secure Backup product family. Oracle Secure Backup is Oracle’s next generation
tape backup management solution and it now provides customers the
flexibility to back up data to either tape or the Cloud.

The Oracle Secure Backup Cloud module can also be used to stream backups
directly to the Cloud. This is particularly useful when the database is also running in the Cloud, using services such as Amazon Elastic Compute Cloud (EC2).

The Oracle Secure Backup Cloud module is implemented using the Oracle
Recovery Manager (RMAN) SBT interface. The SBT interface allows external
backup to be seamlessly integrated with RMAN. Consequently, the Oracle
Secure Backup Cloud module can be used to back up all supported versions of
Oracle Database i.e. Oracle Database 9i Release 2 or higher. In addition, database
administrators can continue to use their existing backup tools – Enterprise
Manager, scripts, etc. – to perform Cloud backups.



Oracle Secure Backup Cloud module is currently available for Linux and Windows
(32-bit only) platforms.
