Backup & Recovery

The Technical Services team for Backup and Recovery have produced a number of documents we call "Blueprints".

These Blueprints are designed to show backup and recovery challenges around specific technologies or functions and how Backup Exec solves these challenges.

Each Blueprint consists of:

  • Pain Points: What challenges customers face
  • Whiteboard: Shows how Backup Exec solves the customer challenges
  • Recommended Configuration: Shows recommended installation
  • Do’s: Gives detailed configurations suggested by Symantec
  • Don'ts: What configurations & pitfalls customers should avoid
  • Advantages: Summarizes the Backup Exec advantages

This Blueprint is designed to help with customers who are utilising OST technology with Backup Exec’s deduplication Option to improve back end storage capabilities within a complex backup environment.

Relentless Information Growth

The data deduplication technology within Backup Exec 2014 breaks down streams of backup data into “blocks.” Each data block is identified as either unique or non-unique, and a tracking database is used to ensure that only a single copy of a data block is saved to storage by that Backup Exec server. For subsequent backups, the tracking database identifies which blocks have been protected and only stores the blocks that are new or unique. For example, if five different client systems are sending backup data to a Backup Exec server and a data block is found in backup streams from all five of those client systems, only a single copy of the data block is actually stored by the Backup Exec server. This process of reducing redundant data blocks that are saved to backup storage leads to significant reduction in storage space needed for backups.

Data has increased the necessity in making greater investments in IT infrastructure, with the increase in the duplication of data and Data protection processes, such as backup, has compound data growth creating multiple copies of primary data made for operational and disaster recovery. This has also made the Backup Infrastructure far more complex. Now that disk-based systems inherently offer faster restores, disk systems can also make backup environments more complex and difficult to manage. This creates a problem for many backup solutions to manage advanced storage device capabilities such as data deduplication, replication, and ability to write directly to tape.

Power of OpenStorage Technology (OST)

Symantec Backup Exec software and the OpenStorage technology (OST) have been designed to provide centrally managed, edge-to-core data protection in order to span multiple sites and provide disk-to-disk-to-tape (D2D2T) functionality and automate Data Movement. The OpenStorage API introduced in Backup Exec 2010 provides automated movement of data between sites and storage tiers and acts as a single Point of Management and Catalog for Backup Data, regardless of where it resides (remote office or corporate data center) or of what type of media it is stored on (disk or tape), or its age (recent backup or long term archive), providing better Control of Advanced Storage Devices.

The OpenStorage initiative allows customers to better utilize advanced, disk-based storage solutions from qualified partners. It gives the ability to ensure tighter integration between the backup software and storage, greater efficiency and performance using an easy-to-deploy, purpose-built appliance that does not have the limitation of tape emulation devices: increasing Performance and Optimization, achieving faster backups to deduplication appliances via a third-party OST plug-in enabled by Backup Exec. In addition it increases control and utilization of information and hardware and improves the speed and reduces the complexity of recovery during a disaster.

If in case, anything happens to your Exchange OST file and it becomes inaccessible or corrupted then you can try some data recovery tool to retrieve data from it. One such tool is available here http://www.recovery-tools.org/exchange-ost/ which can be a recovery as well as conversion application for Exchange or Outlook users.
