Time Machine was overhauled in macOS 11 Big Sur to utilize APFS, Apple's modern file system first introduced in 2016. Specifically, the new version of Time Machine makes use of APFS's snapshot technology. [1] [6] [7] According to Apple, this enables "faster, more compact, and more reliable backups" than were possible previously with HFS+ ...
A version is saved every five minutes, during any extended periods of idle time, or when the user uses "Save a version," which replaces the former "Save" menu item and takes its Command-S shortcut. Saves are made on snapshots of the document data and occur in a separate thread, so the user is never paused during this process. [4]
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.
Most snapshot implementations are efficient and can create snapshots in O(1). In other words, the time and I/O needed to create the snapshot does not increase with the size of the data set; by contrast, the time and I/O required for a direct backup is proportional to the size of the data set.

Similar to archive.today, the Wayback Machine takes snapshots of webpages at certain times, as well as user-initiated on-demand archiving called "Save Page Now" (SPN). [ 2 ] [ 3 ] Wayback and archive.today operate differently, and certain pages can be archived by one but not the other.
Continuous data protection (CDP), also called continuous backup or real-time backup, refers to backup of computer data by automatically saving a copy of every change made to that data, essentially capturing every version of the data that the user saves. In its true form it allows the user or administrator to restore data to any point in time. [1]
The first ever version of Minecraft was released in May 2009, [11] but client-side modding of the game did not become popular in earnest until the game reached its alpha stage in June 2010. The only mods that were released during Minecraft 's Indev and Infdev development stages were a few client-side mods that had minor changes to the game.
