What is backup?

Simply speaking, backup is the process of copying files and databases to another device or media for use in the event the live data is deleted or altered.

There are many different types of backup processes to choose from:

Full: Full backup saves complete files, databases and transaction logs. This is the foundation for all other types of backup processes.

Incremental: This backup strategy is the quickest, but requires the longest recovery time, as you will need to first recover the last full backup, and then each subsequent incremental backup.

Differential: This process backs up only the transaction log and continues to add to it and save all data until the next full backup. This method provides a faster recovery time because only the full backup and latest differential backup would need to be restored.

Synthetic: Synthetic backup combines a full backup and either incremental or differential backups to synthetically create a new, full backup.

Continuous Data Protection (CDP): CDP continuously saves files as they are created or altered, virtually eliminating user's backup windows.

Disk-to-Disk-to-Tape (D2D2T): This process backs up data to a disk-based device where it is stored for a predetermined amount of time before being saved to a tape drive, allowing for quicker recovery times.

Which backup options are right for me?

When looking into a backup solution, determine what software and hardware you'll need. Backup software automates the process of copying data from your servers to the backup media. There are also many add-on options, including the ability to back up databases and applications such as Exchange, SQL and SharePoint, and the ability to capture data stored on users' laptop or desktop hard drives.

An ideal backup environment includes a dedicated server to manage all saved data. This server is attached to the tape drive or autoloader. A tape drive is the device that stores the data on a magnetic tape cartridge for long-term retention. An autoloader is a tape drive with multiple drives that automatically rotates tapes between drives.

Why should I consider backup solutions?

A comprehensive backup plan is integral to business continuity and operations and can help your business with the following:

• Mitigate risk: Effective backup protocols form the foundation of any
  disaster recovery plan.

• Protection from financial loss: Losing intellectual property, customer
  files and sales data can negatively impact your reputation.

• Boost productivity: Automated operations free up IT staff to focus on
  more strategic issues.
