Backup and Recovery
What is backup and recovery?

Backup and recovery are data management practices for the purpose of protecting data from loss or corruption and ensuring data availability in the event of a disaster. These practices are critical for business continuity and data integrity.

Backup is the practice of creating copies of data so the copies can be used to restore data in the event of data loss or corruption. 

Recovery is the practice of restoring data from backup copies to its original or a usable state following data loss, corruption, or disaster.

What are common backup types and methods?

Common backup types and methods

Common backup types are:

  • Full Backups: These are complete copies of all data. This type is the simplest to restore but requires the most storage space and time to complete.
  • Incremental Backups: These are copies of only the data that has changed since the last backup (whether full or incremental). This method is faster and uses less storage but can be more complex to restore.
  • Differential Backups: These are copies of all data that has changed since the last full backup. It strikes a balance between full and incremental backups in terms of storage space and restoration complexity.
  • Mirror Backups: This is an exact copy of the source data, typically without any compression or encryption. It is quick to restore but requires a significant amount of storage space.

Common backup methods are:

  • On-Premises Backups: Backups are stored on local hardware such as tapes, disks, or dedicated backup appliances.
  • Cloud Backups: Data is backed up to a remote cloud storage service.
  • Hybrid Backups: Combines both on-premises and cloud backup solutions to offer the benefits of both methods.
