An NTFS reparse point is a type of NTFS file system object. It is available with the NTFS v3.0 found in Windows 2000 or later versions. Reparse points provide a way to extend the NTFS filesystem. A reparse point contains a reparse tag and data that are interpreted by a filesystem filter driver identified by the tag.
NTFS volume mount points are NTFS filesystem objects—implemented as NTFS reparse points—which are used to mount and provide an entry point to other volumes. Volume mount points are supported by NTFS 3.0, which was introduced with Windows 2000.
When the Object Manager parses a file system name lookup and encounters a reparse attribute, it will reparse the name lookup, passing the user controlled reparse data to every file system filter driver that is loaded into Windows. Each filter driver examines the reparse data to see whether it is associated with that reparse point, and if that ...
Junction points are NTFS reparse points and operate similarly to symbolic links in Unix or Linux, but are only defined for directories, and may only be absolute paths on local filesystems (as opposed to remote filesystems being accessed). They are created and behave in a similar way to hard links, except that if the target directory is renamed ...
Reparse Point (L): The file or directory has an associated re-parse point, or is a symbolic link. Offline (O): The file data is physically moved to offline storage (Remote Storage). Sparse (P): The file is a sparse file, i.e., its contents are partially empty and non-contiguous. Temporary (T): The file is used for temporary storage.
If file data or metadata become corrupt, the file can be deleted without taking the whole volume offline for maintenance, and then be restored from the backup. As a result of built-in resiliency, administrators do not need to periodically run error-checking tools such as CHKDSK when using ReFS.
A snapshot is a read-only point-in-time copy of the volume. Snapshots allow the creation of consistent backups of a volume, ensuring that the contents do not change and are not locked while the backup is being made. The core component of shadow copy is the Volume Shadow Copy service, which initiates and oversees the snapshot creation process.
Backup and Restore [1] (formerly Backup and Restore Center [2]) is the primary backup component of Windows Vista and Windows 7. It can create file and folder backups, as well as system images backups, to be used for recovery in the event of data corruption , hard disk drive failure , or malware infection.
