Behind the current active window are stacked windows, with each window representing a snapshot of how that folder or application looked on the given date and time in the past. Upon its launch, Time Machine "floats" the active Finder or application window from the user's desktop to a backdrop depicting the user's blurred desktop wallpaper. Time Machine's user interface when retrieving a file uses Apple's Core Animation API. Īt least in some circumstances, encryption appears to be required (instead of merely optional) in the new version of Time Machine. USB- or Thunderbolt-connected) and network-connected Time Machine backup destinations are formatted as APFS by default, though Time Machine can continue backing up to existing HFS+ backup volumes." There is no option to convert existing, HFS+-based backups to APFS instead, users who want to benefit from the advantages of the new, APFS-based implementation of Time Machine need to start with a fresh volume. A more modest yet nevertheless significant advantage was noted as well for backups to network-attached disks. An independent evaluation of this claim found that macOS 11's Time Machine implementation in conjunction with APFS was 2.75-fold faster upon initial local backup and 4-fold faster upon subsequent backups relative to macOS 10.15's Time Machine implementation using HFS+. According to Apple, this enables "faster, more compact, and more reliable backups" than were possible previously with HFS+-formatted drives. Specifically, the new version of Time Machine makes use of APFS's snapshot technology. Time Machine was overhauled in macOS 11 Big Sur to utilize APFS, Apple's modern file system first introduced in 2016. At that point, Time Machine deletes the oldest weekly backup. Time Machine saves hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for everything older than a month until the volume runs out of space. Time Machine may also be used with other external or internal volumes. Apple's Time Capsule, which was introduced in 2008 and discontinued in 2018, acted as a network storage device specifically for Time Machine backups, allowing both wired and wireless backups to the Time Capsule's internal hard drive. Some of the legacy support can be re-enabled by using hand-tuned configuration options, accessed through the Terminal.
Earlier versions worked with a wide variety of NAS servers, but later versions require the server to support a recent version of Apple's Apple Filing Protocol (AFP) or a recent version of the Server Message Block (SMB) protocol, and Time Machine no longer works with servers using earlier versions of SMB. As snapshots age, they are prioritized progressively lower compared to your more recent ones.” įor backups to a network drive, Time Machine allows the user to back up Mac computers over the network, and supports backing up to certain network attached storage devices or servers, depending on the version of Time Machine. Time Machine captures the most recent state of your data on your disk.
When using mac time machine does it backup data within apps Offline#
“Time Machine is a backup utility, not an archival utility, it is not intended as offline storage. Emails, contacts, text documents, presentations) without leaving the application.
It also works within a number of applications such as Mail and iWork, making it possible to restore individual objects (e.g. It allows the user to restore the whole system or specific files. Time Machine creates incremental backups of files that can be restored at a later date.
