What is Time Machine and Why You Need It?

Time Machine is Apple’s built-in backup solution that automatically creates incremental backups of your entire Mac system.

In 2025, with the increasing reliance on digital data for work, personal files, and creative projects, having a robust backup strategy isn’t just recommended—it’s essential.

Why Time Machine Stands Out:

• Automatic backups every hour for the past 24 hours
• Daily backups for the past month
• Weekly backups for all previous months
• Complete system restoration capabilities
• File versioning to recover previous versions of documents
• Zero configuration required for basic setup

According to recent data recovery statistics, 60% of Mac users who experience data loss don’t have any backup system in place. So, don’t become a part of this statistic.
