Contents. Overview Time Machine creates incremental backups of files that can be restored at a later date. It allows the user to restore the whole system or specific files from the Recovery HD or the macOS Install DVD.
The AirPort Time Capsule (originally named Time Capsule) is a wireless router sold by Apple. With the Time Machine backup software utility introduced in Mac OS X 10.5. The backup disk can also be used by Windows-based computers, and the. 'Mac OS X v10.6: About Wake on Demand (Apple Article HT3774)'. Feb 6, 2014 - When DOS was born, popular hard drives only had 5MB or 10MB of storage space. For exFAT in Mac OS X 10.6.5 (Snow Leopard) and later versions of OS X. Apple added read-only support for NTFS in 2003 with Mac OS X 10.3 (Panther). (It's a Windows program that reads Linux and Mac disks.).
It works within, and several other compatible programs, making it possible to restore individual objects (e.g. Emails, photos, contacts, calendar events) without leaving the application. According to an Apple support statement: “Time Machine is a backup utility, not an archival utility, it is not intended as offline storage. Time Machine captures the most recent state of your data on your disk. As snapshots age, they are prioritized progressively lower compared to your more recent ones.” For backups to a network drive, Time Machine allows the user to back up Mac computers over the network, and supports backing up to certain devices or servers, depending on the version of Time Machine. Earlier versions worked with a wide variety of NAS servers, but later versions require the server to support a recent version of Apple’s, and Time Machine no longer works with servers using the protocol typical for Windows servers. Some of the legacy support can be re-enabled by using hand-tuned configuration options, accessed through the.
Apple's acts as a device specifically for Time Machine backups, allowing both wired and wireless backups to the Time Capsule's internal hard drive. Time Machine may also be used with any external or internal volume. 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.
At that point, Time Machine deletes the oldest weekly backup. User interface Time Machine's when retrieving a file uses Apple's. Upon its launch, Time Machine 'floats' the active or application window from the user's desktop to a backdrop depicting the user's blurred desktop wallpaper. Behind the current are stacked windows, with each window representing a of how that folder or application looked on the given date and time in the past. When toggling through the previous snapshots, the stacked windows extend backwards, giving the impression of flying through a 'time tunnel.' While paging through these 'windows from the past,' a previous version of the data (or presently deleted data) may be retrieved. Storage Time Machine works with locally connected storage disks, which must be formatted in the HFS+ volume format, as well as with remote storage media shared from other systems, including Time Capsule, via the network.
When using remote storage, Time Machine uses. This acts as an isolation layer, which makes the storage neutral to the actual file system used by the network server, and also permits the replication of the backup from one storage medium to another. Sparse bundles are mounted by macOS like any other device, presenting their content as a HFS+ formatted volume, functionally similar to a local storage. Requirements Time Machine places strict requirements on the backup storage medium. The only officially supported configurations are:.
A hard drive or partition connected directly to the computer, either internally or by a bus like or, and formatted as. A folder on a journaled HFS+ file system shared by another Mac on the same network running at least Leopard. A drive shared by an Apple on the same network. A drive connected to an Apple 802.11ac model on the same network. (Earlier generations of the AirPort Extreme are not supported.). Local network volumes connected using the or via an share that advertises a number of capabilities. On a Time Capsule, the backup data is stored in an HFS+ and accessed via.
Although it is not officially supported, users and manufacturers have configured FreeBSD and Linux servers and systems to serve Time Machine-enabled Macs. Operation Time Machine creates a folder on the designated Time Machine volume (local or inside a remote ) into which it copies the directory tree of all locally attached disk drives, except for files and directories that the user has specified to omit, including the Time Machine volume itself. Every hour thereafter, it creates a new subordinate folder and copies only files that have changed since the last backup and creates to files that already exist on the backup drive. A user can browse the directory hierarchy of these copies as if browsing the primary disk. Some other backup utilities save deltas for file changes, much like version control systems.
Such an approach permits more frequent backups of minor changes, but can often complicate the interaction with the backup volume. By contrast, it is possible to manually browse a Time Machine backup volume without using the Time Machine interface; the use of hard links presents each backup to the user as a complete disk copy. Time Machine appears to create multiple hard links to unmodified directories. Multiple linking of directories is different from conventional UNIX operating systems. As a result, tools like cannot be used to replicate a Time Machine volume; replication can only reliably be done by imaging the entire filesystem.
Apple system events record when each directory is modified on the hard drive. This means that instead of examining every file's modification date when it is activated, Time Machine only needs to scan the directories that changed for files to copy (the remainder being hard-linked). This differs from the approach taken by similar backup utilities and, which examine modification dates of all files during backup. Time Machine is also available in the, and installation process. One of the features in the interface is to re-install the contents of a Time Machine backup.
In other words, a hard drive can be restored from a Time Machine backup in the event of a catastrophic crash. Introduced the ability to use multiple volumes simultaneously for Time Machine operations. When the user specifies more than one volume to use, macOS rotates among the desired volumes each time it does a backup. Coding differences between OS X Mountain Lion and Mavericks have resulted in compatibility issues related to Time Machine's system restoration functionality.
Time Machine backups created by Apple computers purchased as recently as late 2012 cannot be used for system restoration on 2013 or 2014 models. However, the data from the backup can still be recovered by directly accessing the files from the Time Machine Volume. See also. References. Retrieved December 21, 2007.

ToddZ possible work around: According to several reports around support forums and from e-mail correspondence from our readers, this issue appears to be related to the Ethernet settings on notebooks. MacFixIt reader “Andreas S.” reports: “It appears that if the Ethernet is not enabled (airport only network settings) that on the MacBook Pro the sleep only works once and crashes the second time.” To re-enable the Ethernet port settings: 1. Open System Preferences Network 2-1.
If you see your Ethernet port in your list of network ports (on the left-side of the window) and it says “Inactive,” activate the port by clicking the gear wheel icon and selecting “Make Service Active.” Click “Apply.” 2-2. If you do not see your Ethernet port in your list of network ports (on the left-side of the window), click the “+” button in the bottom-left corner. In the “Interface” drop-down menu, select “Ethernet.” 4. Enter a name and select “Create.” You should see your new Ethernet connection appear. Click “Apply.” Note: If you are having this issue and your Ethernet port is already enabled, try disabling it (using the gear wheel icon menu “Make Service Inactive”).
Log out or restart your Mac, then enable it. Be sure to “Apply” your changes. Test your MacBook or MacBook Pro by closing the clamshell. Be sure to try this twice as most reports point to the second attempt at sleep as being the culprit for the freeze.
If it does not work, try resetting your Mac and test again. Dick D I am having the same “sleep” problem with my MacBook Pro as the ones mentioned above. Disk drive runs continually while it is “asleep,” and case gets very hot. Will not awaken from the non-sleep “sleep” mode. Occasionally it goes to sleep and awakens as desired IF I have selected “sleep” from the Apple menu and not by closing the cover.
As long as no programs, such as mail, were running when I put it to sleep, it awakens okay. Have not had this happen enough to ensure it is a real pattern yet. Catmanrog Richard – What OSX version are you running?
