Understanding Data Backup and Recovery

Your computer database will breakdown at some point. This cannot be controlled. What you can control, though, is how you approach the process of data backup and recovery. There are several guidelines associated with database recovery, and by following them, you are sure to create a sound backup.

 

 

 

 

 

 

 

Defend Against Database Hazards

Your database can crash for several reasons, some of which include instance failures, application failures, and media failure. In order to adequately protect your system, you must consider all of the problems that could befall your database. You can safeguard your database using several techniques:

  • UPS systems
  • Mirrored disks
  • Failover technology

Two Backup Strategies

It is essential for you to create backup copies of all your data. In general, backing up involves the production of image copies, of which there are two kinds: full and incremental backups. Full backups are copies of all the data in a particular database. Incremental backups only contain data that was altered since the last backup. Regardless of the type of backing up you do, it is important to maintain a consistent backup strategy, which ensures greater efficiency.

Data backup and recovery is a complex yet essential process. You never know when your database will crash, but you do know that breakdowns are inevitable. By backing up your system, you guarantee that all of your information is thoroughly protected.
