Traditional backups only restore data from the time the backup was made. True continuous data protection, in contrast to "snapshots", has no backup schedules. [5] When data is written to disk, it is also asynchronously written to a second location, either another computer over the network [6] or an appliance. [7]
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.
Multiplexing can reduce backup times when backing up data from non-solid state sources containing millions of small or highly fragmented files, which require very large amounts of head-seeking using traditional mechanical hard drives, and which significantly slow down the backup process.
NTBackup (also known as Windows Backup [1]: 20.1 and Backup Utility [1]: 20.4 ) is the first built-in backup utility of the Windows NT family. It was introduced with Windows NT 3.51 . NTBackup comprises a GUI ( wizard-style ) and a command-line utility to create, customize, and manage backups.
Time Machine is the backup mechanism of macOS, the desktop operating system developed by Apple. The software is designed to work with both local storage devices and network-attached disks, and is commonly used with external disk drives connected using either USB or Thunderbolt .

Boot Camp 4.0 for Mac OS X 10.6 Snow Leopard version 10.6.6 up to Mac OS X 10.8 Mountain Lion version 10.8.2 only supported Windows 7. [3] However, with the release of Boot Camp 5.0 for Mac OS X 10.8 Mountain Lion in version 10.8.3, only 64-bit versions of Windows 7 and Windows 8 are officially supported. [4] [5]
A reverse incremental backup method starts with a non-image full backup. After the full backup is performed, the system periodically synchronizes the full backup with the live copy, while storing the data necessary to reconstruct older versions. This can either be done using hard links—as Apple Time Machine does, or using binary diffs.
