Choosing the right file system is essential for data protection. This article aims to explain the differences between journaled and non-journaled file systems, to recommend journaled file systems suitable for different operating systems, and to highlight why certain file systems and practices should be avoided.
1. What is a Journaled File System?
A journaled file system maintains a transaction log that tracks all changes made to files or the disk, offering additional protection for data integrity and system recovery.
2. For Windows Users
Recommended File System: NTFS
Why: Compared to the previous FAT32, NTFS offers better data integrity protection thanks to its journaling capabilities.
3. For MacOS Users
Recommended File System: APFS (for newer Macs) or HFS+
Why: APFS is Apple's latest file system, with excellent journaling capabilities. For older devices, HFS+ remains a reliable choice.
4. For Linux Users
Recommended File System: Ext4
Why: Ext4, with the journaling features of Ext3 and many modern optimizations, is the preferred choice for Linux.
5. Going Further on File Systems
Advantages of Journaled File Systems: They ensure consistency, making them less likely to lose data and faster to repair.
Disadvantages of Non-Journaled File Systems: Like exFAT, despite its compatibility, the lack of journaling makes it vulnerable to data corruption.
6. Risks and Recommendations for External Hard Drives
External hard drives are more fragile and vulnerable to physical and electrical damage. Avoid using large software or files directly on them. Instead, transfer project files to your computer's internal storage and make regular backups.
7. Special Reminders
Limit the Use of exFAT: MONTGA TECH advises you to limit the use of the exFAT file system for storing critical data.
Be Careful with Large Software Files: Using them directly on external drives can increase the risk of corruption. Always make sure to have a backup before proceeding.
Conclusion: To ensure the security of your data, it is essential to choose the right file system and adopt good data management practices. MONTGA TECH is at your service to offer expert advice to protect your data.
