Or worse, a ransomware attack encrypts all your critical business data, demanding a hefty ransom for its release. This is where having a robust data backup and recovery plan becomes crucial.

How It Works

Here’s what’s involved in effective data backup and recovery:

  • Full backup: Copies all selected data each time. Slow, but provides a complete snapshot.
  • Incremental backup: Copies only the changes since the last backup. Faster, but requires the last full or incremental backup for restoration.
  • Differential backup: Copies all changes since the last full backup. A compromise between full and incremental.
  • Cloud backup: Stores ...
