In one-way file synchronization, also called mirroring, updated files are copied from a source location to one or more target locations, but no files are copied back to the source location. In two-way file synchronization, updated files are copied in both directions, usually with the purpose of keeping the two locations identical to each other ...
Dropbox brings files together in one central place by creating a special folder on the user's computer. [15] The contents of these folders are synchronized to Dropbox's servers and to other computers and devices where the user has installed Dropbox, keeping the same files up-to-date on all devices.

Disk quotas can be used to limit the amount of space taken up by users' special folders. The %username% and %userprofile% environment variables can also be used with Folder Redirection. Up to Windows XP, the Application Data, Desktop, My Documents, My Pictures, and Start Menu special folders can be redirected to a file server. Windows XP also ...
This folder serves as a buffer for users of a computer to share files. By default this folder is accessible to all users that can log on to the computer. Also, by default, this folder is shared over the network, although anonymous access (i.e. without a valid password-protected user account) to it is denied.
Disk cloning is the process of duplicating all data on a digital storage drive, such as a hard disk or solid state drive, using hardware or software techniques. [1] Unlike file copying, disk cloning also duplicates the filesystems, partitions, drive meta data and slack space on the drive. [2]
A block, a contiguous number of bytes, is the minimum unit of storage that is read from and written to a disk by a disk driver.The earliest disk drives had fixed block sizes (e.g. the IBM 350 disk storage unit (of the late 1950s) block size was 100 six-bit characters) but starting with the 1301 [8] IBM marketed subsystems that featured variable block sizes: a particular track could have blocks ...
It can be used in desktop environments, for example to efficiently synchronize files with a backup copy on an external hard drive. A scheduling utility such as cron can carry out tasks such as automated encrypted rsync-based mirroring between multiple hosts and a central server.
