Foreword:
One of the advantages of multi-user operating systems is the ability to assign different operating systems, including permissions to certain functions, to different computer users.
1. Overview of NTFS:
NTFS Overview
NTFS (New Technology File System) is a file system for the Windows NT operating environment and the Windows NT Advanced Server network operating system environment. The goal of NTFS is to provide: reliability, through recoverability (event tracking ) and Implementation of fault-tolerant features for hot location; a platform for increased functionality; support for POSIX requirements; elimination of limitations in FAT and HPFS file systems.
NTFS provides long file names, data protection and recovery, and security through directory and file permissions. NTFS supports large hard drives and storing files on multiple hard drives (called spanning partitions). For example, a large company's database may be so large that it must span different hard drives. NTFS provides built-in security features that control file ownership and access. Files on NTFS partitions are not directly accessible from DOS or other operating systems. If you want to read and write NTFS partition files under DOS, you can use third-party software; now, NTFS-3G can be used on Linux systems to read and write NTFS partitions perfectly, without worrying about data loss. This is part of the Windows NT security system, but only when using NTFS.
2. Common file systems include:
Commonly used file systems include: FAT, EXT, NTFS, HFS, ZFS, UFS, VMFS, REFS , but Windows Server 2016 supports NTFS and REFS.
3. Overview of REFS:
REFS (Resilient File System) is a newly introduced file system in Windows Server 2012. In the early days, it could only be used to store data, but now it can boot the system; it can also be used on mobile hard drives.
REFS is mostly compatible with NTFS. Its main purpose is to maintain high stability, automatically verify whether the data is damaged, and try its best to recover the data. If used in conjunction with the introduced Storage Spaces, it can provide better data protection. At the same time, performance has been improved for processing hundreds of millions of files.
4. The difference between NTFS and REFS:
File naming convention:
ReFS uses the file naming convention for which it is famous, based on the SFS (Simple File System) naming convention. For the file naming conventions on which it is famous, such as compatibility in different file systems, namespace consistency, etc.
File system metadata:
ReFS has made some optimizations and improvements in file system metadata. In NTFS, metadata is stored in separate file formats (such as inodes). This makes metadata modifications relatively independent.
File access performance:
Because ReFS uses distributed metadata storage and speeds up metadata reading, it improves file access performance.
Security:
ReFS has been enhanced in terms of security. NTFS is weak in terms of security because it stores metadata in a separate file format, which makes it easier for attackers to access and modify file system metadata. ReFS improves the security of the file system by using distributed metadata storage and encryption technology.
Reliability:
ReFS has improved in terms of reliability. NTFS may experience file corruption or loss under certain circumstances, which may result in data loss or file system corruption. ReFS improves the reliability of the file system by using distributed metadata storage and encryption technology.
Manageability:
Because ReFS uses distributed metadata storage and encryption technology, administrators can more easily manage and maintain the file system.
