Data Backup Strategies

Data backup strategies are methods used to securely copy and store important information to prevent loss due to accidents, hardware failures, or disasters. Common strategies include: 1. **Full Backup**: Copying all data every time. 2. **Incremental Backup**: Saving only changes made since the last backup. 3. **Differential Backup**: Saving changes made since the last full backup. Backup locations can vary, including external hard drives, cloud services, or physical storage. Regularly testing backups ensures they work when needed. A solid strategy often combines these methods for efficiency and security, ensuring data is recoverable when necessary.
