1. Data: Backups and Restoration
Data backup and restoration are fundamental to data protection, disaster recovery, and business continuity. Whether for individuals or enterprises, backups prevent data loss due to hardware failure, malware attacks, accidental deletion, or system crashes.
a. File Backups
Definition:
File backup is the process of duplicating selected files or directories—such as documents, media, or project folders—to a separate storage device or location without copying the entire operating system or system configuration.
Characteristics:
- Focuses on individual files/folders
- Fast and space-efficient
- Easy to manage and schedule
- Doesn’t protect against OS failure or software misconfiguration
Use Case:
Ideal for users who:
- Need to back up personal files, such as photos or documents
- Want to ensure project-specific data is safe
- Are using shared or public machines where system-level backups are restricted
