Restore mac to earlier date time machine

The software is designed to work with AirPort Time Capsule , the Wi-Fi router with built-in hard disk , as well as other internal and external disk drives. Time Machine creates incremental backups of files that can be restored at a later date. It works within Mail , iWork , iLife , and several other compatible programs, making it possible to restore individual objects e.

Step Two: Choose Hard Drive

According to an Apple support statement:. 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 network attached storage devices or servers, depending on the version of Time Machine. Some of the legacy support can be re-enabled by using hand-tuned configuration options, accessed through the Terminal.

Time Machine

Apple's Time Capsule acts as a network storage 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. 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. 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.

When toggling through the previous snapshots, the stacked windows extend backwards, giving the impression of flying through a "time tunnel. When using remote storage, Time Machine uses sparse bundles. 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.

Restoring without Time Machine

Time Machine places strict requirements on the backup storage medium. The only officially supported configurations are:. Although it is not officially supported, users and manufacturers have configured FreeBSD and Linux servers and network-attached storage systems to serve Time Machine-enabled Macs.

Time Machine creates a folder on the designated Time Machine volume local or inside a remote sparse image 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 hard links 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 creates multiple hard links to unmodified directories. As a result, tools like rsync 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 rsync and FlyBack , which examine modification dates of all files during backup.

    One of the features in the Migration Assistant 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. When the user specifies more than one volume to use, macOS rotates among the desired volumes each time it does a backup.
