Data Backup and Disaster Recovery - The Basic
Difference

• Disaster recovery and Data backup might look same
  to a layman but they are very different concepts,
  disaster recovery is not possible without backup
  in the first place. Backup data is historically
  collected data making redundant copies of data.
  Disaster recovery on the other hand, is all about
  how backups and other fault-tolerant mechanisms
  are put to work after a disaster occurs. Disaster
  recovery is having the tested withheld data to
  get systems restored and running as quickly as
  possible, as well as the associated data.
• The need for Data recovery and backup in a data
  center
• Data recovery is the process of restoring data
  that has been lost by mistake and important files
  are deleted , File system format or Damage and
  files corrupted or made inaccessible for any
  reason. That could be anything and there are many
  reasons to data loss ranging from a disk crash on
  a users device to a data centre crushed by a
  meteorite. When such a failure happens, it is not
  just data that needs restoring, but the full
  working environment in other words, disaster
  recovery.

• Robust methods employed in a data center for Data
  Recovery and Backup
• Data backup simply means a copy of your data is
  replicated to another device or location. When
  your system data gets deleted and the system is
  formatted either by mistake or data has not been
  saved before formatting. Generally your file size
  in clusters is commonly 32 KB, but it varies with
  drive size. But if your data is large and files
  are larger you need data recovery software.
• Recovery data is divided into two categories
• Data required keeping current values.2) Data to
  make the restoration of previous values possible.
• Possible Levels of Recovery
• Data recovery to the correct state. Recovery
  to a check pointed correct state. Recovery to a
  possible previous state. Recovery to a valid
  state. Recovery to a consistent state. Crash
  resistance (prevention).
