If you created a backup of your Mac using Time Machine, you can enter Time Machine to restore specific files from that backup.
To restore everything from your backup, not just specific files, follow the steps to restore your Mac from a backup.
If your computer contains data that is valuable to you, such as irreplaceable photos and your music library, you should back up your files to some kind of external media. This will protect your computer files, should they accidentally get deleted or become corrupted. It is possible to recover files that seem to have been erased or overwritten, however, all this is of no use if your computer gets stolen or destroyed. The Apple Time Machine feature makes both backing up and recovering data very straightforward. Let's take a look at how it works, and outline a few back up strategies.
Contents
There are several ways to back up your data. However, the most convenient method is to use OS X's built-in Time Machine application in conjunction with an external hard drive. Such drives are fast, capacious, and connect via FireWire, Ethernet, or USB2 cable. It is also possible to connect wirelessly over a network router or hub. Apple Time Machine, meanwhile, can be set up in a couple of minutes, and then be forgotten about. It can even make the process of recovering lost data rather enjoyable.
Note that while the wireless option is great for incremental backups, the initial backup of the whole system should be carried out using some sort of cable, as it can take days if attempted wirelessly.
Time Machine creates incremental backups of files that can be restored at a later date from the Recovery HD, or the macOS Install DVD. The feature works within iWork, iLife, and other compatible programs. The Time Machine software application has been designed to work with the Time Capsule storage product, as well as other internal and external disk drives.
When you connect a hard drive to your Mac, Time Machine will open automatically and ask if you would like to make a backup. If Time Machine does not open, open it from the Dock, Applications, or go to System Preferences and choose Time Machine. Next, hit Choose Backup Disk, and select your connected drive from the list.
By default, Apple Time Machine will back up all the data on your machine the first time it is used. Then, over time, the feature appends accumulative updates of all the files that change. That means the amount of backed up data will grow over time, so if possible, use a backup drive with enough capacity to store all your data. When Time Machine runs out of space, it automatically starts deleting the oldest backed up files to make room for newer ones.
If you think space will be an issue, or if you simply do not want to back up all of your data, Apple Time Machine can exclude selected data and folders. To do this, hit the Options button within System Preferences – Time Machine, and then use the '+' button to add items to the Do not back up list. If you choose to exclude any folder that contains system files, you will be offered the option to Exclude All System Files – the logic being that these files can be restored from the System Restore disc that came with the Mac.
This is where the fun begins. When you're ready to recover a deleted file or folder, or restore a file or folder to an earlier state, select the item in question in Finder, and then launch Time Machine from the Dock or Applications.
Similarly, to restore Photos, iTunes, Address Book, and other apps to a previous state, click the window of the app in question and launch Time Machine.
The Mac is then whisked off to what appears to be the edge of a black hole. Here you can skip through your Mac's backups by either clicking through the stack of windows, tapping on the arrows, or scrolling up and down the timeline on the screen's right-hand edge. When you find the item in its desired state, hit Restore.
If you intend to use an external drive with Apple Time Machine, or with any other application that accumulates incremental backups, aim to purchase a drive with a capacity roughly double that of the amount of data you intend to back up. When making your calculations, take into consideration how much media you are likely to accumulate over the next year or two. If you intend to use Time Machine, also take into account that the larger the drive, the further back in time you will be able to go to restore files. Apple's Time Capsule device is a good option, as it acts as a wireless router.
If you do not want to give up your entire hard drive to Apple Time Machine, first split the drive into two partitions using Disk Utility, then select one of the partitions as your backup drive in Time Machine.
By default, Apple Time Machine will carry out regular backups according to the schedule specified in System Preferences – Time Machine. However, if your Mac is not permanently connected to your backup drive, backups will take place whenever you plug the drive in.
You can use Time Machine to back up multiple Macs to the same drive, as long as the drive has enough space.
It may not be worth the time to back up applications that came with your Mac, or that you purchased, as you can easily reinstall them from the original discs. Likewise, you can download and install previously downloaded software. However, consider backing up any applications that may no longer be available, or are only available in new versions, when you prefer an older one. You may also want to back up an application that is too big, and may be a hassle to re-download. One strategy is to keep a copy of the original compressed files that you download in a folder within your home folder and back up these.
If you are backing up your home folder, think about whether you have ever saved its contents elsewhere, such as shared widgets, screen savers, or fonts in Macintosh – HD – Library. The items on your desktop are covered if you back up your home folder. If you are backing up selectively though, do not forget anything important that you keep on your desktop.
When backing up your Mac, you ideally want to cover everything that you couldn't recover, including photos, emails, music, videos, bookmarks, preferences, calendars, and contacts. Of course, the obvious way to make sure you do not forget anything is to back up the entire contents of your hard drive (this is the Time Machine default option).
A slightly more efficient alternative is to back up only your home folder. This way, you will be able to restore all your personal files and data, but you will not waste space backing up applications or OS X system files that could be easily reinstalled from the original discs or downloads.
If there is more than one user account set up on your Mac, there will be more than one home folder. If you have administrative powers, you could deal with them all at once by backing up the entire Users folder, found in the top-level of Macintosh HD.
If you don't have room for your entire home folder, you will need to be more selective. Here are a few pointers:
The music files that make up your iTunes Library live within your home folder under Music – iTunes – iTunes Music. You can back up artists or albums from there, but if you want to retain playlists, album artwork, and other such extras, you will need to back up the entire iTunes folder.
You can back up individual photos, however it is better to safeguard your entire albums, events, and other such data. Simply back up the Pictures – Photos Library, which contains all of your photos.
You can back up the entire Library folder within your home folder, as this contains things such as contacts, emails, and calendars.
It the space is restricted, at least back up your email files. If you use Apple Mail, your email files will be located within Library – Mail. For other email clients, look for a folder named after the application in the home folder's Documents or Library folders.
To back up your bookmarks in Safari, back up the Bookmarks.plist file, found within Library – Safari. If you use Firefox, back up Library – Application Support – Firefox. You can also turn to Xmarks. Audio editor 1 4 11.
Address Book contacts and calendars are found under Library – Application Support – Address Book, and Library – Calendar app respectively.
You do not need to back up the fonts that came installed with OS X, but any you have added can be backed up via the various Fonts folders.
If you have an external hard drive, flash drive, or even an iPod, you can back up individual files or folders by dragging and dropping them onto the device in question. First, create a folder on the drive and name it with a date. Each time you overwrite the contents, rename the folder with the new date. This way you can easily see when you last backed up. Other back up options include the following methods:
CD, DVD, and USB flash drives: You can back up files onto writeable discs, or a USB flash drive. CDs are not ideal because of their relatively small capacity. DVDs are better, but the whole process is still slower and more cumbersome than using an external drive. USB flash drives are inexpensive and eminently portable – great for backing up essential documents.
Online backups: Backing up data online is ideal, as your files are duplicated to a remote location. However, this option is for backing up key files rather than your whole system. iCloud, for example, features tools for backing up online, though you will get more storage space for your money with a dedicated online storage service.
You can also set up an email account with an online provider such as Google Mail. You can back up key files by emailing them to that account. However, with most accounts you are limited to sending a set amount of data per email.
You can also back up data with your iPod. In fact, iPods are basically just external hard drives, or flash drive storage drives, in pretty cases. iPods do not work with Apple Time Machine, but you can use them to manually back up and transfer all kinds of files – without even affecting the ability of your iPod to play music. First, attach your iPod to your Mac. Then, open iTunes and check Enable Disk Use under the Summary tab. The iPod will now function exactly like any other hard drive, when you attach it. Now its icon will appear on the desktop and Finder Sidebars, ready to receive files. Note that, as with any other drive, you will now have to eject the iPod before physically disconnecting it – even if you are just using iTunes.
If there is room on the iPod, you could back up your entire system.
However, if you are short of space, you may want to add files selectively – perhaps avoiding music and/or photos that are already stored on the iPod.
Note that Apple Time Machine places strict requirements on the back up storage medium. According to Wikipedia, the officially supported configurations are:

/Mac Tips /What Does Time Machine Backup? The Ultimate Guide
Time Machine uses a unique method that mimics complete backups after creating a copy for modified files at hourly intervals. Time Machine runs like clockwork without manual upkeep or fuss. It only duplicates a file if altered, but this generates snapshots for every backup with hard links for each item on the backed-up drive.
But the stark contrast with proprietary backup tools is that it not only mothballs spare duplicates of all files but also memorizes how your Mac looked on any day-so you can walk back in time. But exactly what does time machine backup? At the outset, Time Machine does not back up everything, unlike duplication-centered solutions like MacDaddy.

Time Machine uses a hard link that mimics and behaves like a separate clone of a file accessible via the Finder or Terminal. The hard link keeps the file extent uniquely once on a drive. Each instance of the file presents a link to that one special version. They're removable without purging the original until you remain with one link.
The hard-link system benefits include intuitive navigation via Finder, and also a simple approach of reinstating a snapshot even without extra operations. It also allows you to delete snapshots without banishing data associated with other backups.
In case you inadvertently remove your recovery partition and you want to restore it back, you need to regenerate it. Restore everything, reinstall macOS and then load on everything with Time Machine.
Contrary to the popular opinion that Time Machine backs up everything, it excludes a variety of files based on ecosystem rules. Accordingly, this nomenclature rules out cache files, log files, junk, and certain app settings.
Unlike Time Machine, cloud services garbage down junk files and eat up precious space. iMyMac offers thoroughbred cleanup and optimization tools to keep clutter at bay. It zeroes in on system junk like broken links, cache files and vestiges of uninstalled apps.
You only need to run regular scans and farm out all types of redundant content. iCloud's 5GB storage space will be filled to the brim quickly if you allow junk files to claim gigabytes of room. Mac Cleaner is a safe pair of hands and a preventative measure to salvage hard disk space.
It's the go-to all-in-one system maintenance software to breeze through cleanup and wipe out all types of clutter. It comes with a Free Trial to erase a host of files excluded from Apple's Time Machine backup. Install it to remove junk that may end up in your backups.
Temporary and system-specific files fall outside Apple's Time Machine. By default, it does not back up:
It applies to all lineups of Mac OS X equipped with Time Machine.
Time Machine comes in handy for pre-update backup. So how to back up your Mac with Time Machine? Below are the steps:
Plug in an external storage like a USB or Thunderbolt drive. Check whether you have a backup disk sanctioned by Apple for use with Time Machine.
When you plug in the drive, you should encounter a prompt to use it as your Time Machine backup disk. If you don't see it, navigate to Apple menu > System Preferences > Time Machine.
Check the Back Up Automatically field. Hit Select Backup Disk. Hp scanner mac software.
Highlight the disk you wish to use. To bolster the backup, check the field to Encrypt backups, but it adds the time taken to get the job done. Finally, hit Use Disk. After you configure a backup disk, Time Machine kicks off automatic data back up without diminishing workflow efficiency.
To launch a manual Time Machine backup, go to the menu bar and click the Time Machine icon. Midi keyboard app for pc. Highlight Back Up Now in the menu. Time Machine backs up everything from soups to nuts. For instance, Time Machine will do a fresh install of specific apps, folders, and handpicked files. As long as you know where to find your files on your HDD, you can create a backup.
Duplication-based tools like CCC, MacDaddy, and SuperDuper will back up literally everything. However, these tools lock out some files by default like temporary or system-specific files recommended for exclusion by Apple. Look for a trouble-free experience to create a full backup or clone. They come in handy for generating bootable clones for a backup system. You can create precise copies of your hard drive, Mac OS X startup drive, or Apple iPod.
If you have upgraded your iCloud storage, it's a good option to backup troves of data. You can select Desktop and Documents folder, Mail, Pages, and Numbers. It's helpful for Mac users with more than one Apple device.
Apart from iCloud, you can use Dropbox, Google Drive, and other cloud backup solutions. They allow you to share files or storing collaborative data but we wouldn't recommend them to back up all your files. You wouldn't easily extract a clone on your computer if you lose it. You could have a downloadable disc image of your system in the cloud.
Apple preinstalls its backup software, Time Machine in macOS. It's pretty easy to use armed with an external storage source, hard drive, or SSD to do the trick. Time Machine not only backs up your Mac but also generates incremental copies so you can retrieve an earlier version of a file if you need it.
You may want to set up Time Machine on NAS drive to back up wirelessly, but it runs at a snail's gallop. Alternative backup software with a clever mix of features puts Apple's tool in the shade because you can use it to boot from another Mac. Ms word for mac student discount.
