On Apple laptops, like the MacBook, MacBook Air, and MacBook Pro, Time Machine includes the added feature of creating local snapshots so that, if you disconnect your MacBook from its external hard drive, you'll still have backups stored on your internal hard drive so you can recover data if you need to.
Yosemite Server Backup performs disk-to-disk and disk-to-tape backups of Windows and Linux machines and performs complete system restores in the event of system failure. It supports a wide variety of tape-loading and cartridge devices and robotic libraries for implementing multi-tiered backup and archiving strategies.
Local snapshots are invaluable for certain situations when you're out and about and need to recover data but don't have your backup hard drive. They also, eventually, start taking up noticeable space on your hard drive.

Why do I have 100 GB of backups on my hard drive?
You need an external hard drive in order to set up and use Time Machine because that's where your backups are stored. So why do you have a large number of backups taking up space on your MacBook's internal hard drive? Because of local snapshots.
As soon as you set up Time Machine on your Mac laptop, local snapshots are created automatically. Time Machine makes one daily snapshot every 24 hours when you start up your MacBook and also stores weekly snapshots. It keeps those weekly snapshots on your internal hard drive until you start to get low on storage. So, if you've been backing up your Mac for years with Time Machine, you could potentially have 100 GB of backups stored in your internal hard drive, as long as you have space for them.
How do I get rid of all these backups?
First, let me preface this by saying that you shouldn't worry about those backups and all the space they are taking up. If everything is working properly, Time Machine will automatically delete the oldest snapshot backups as soon as your internal hard drive has less than 20% of storage space left. If you then, say, download some large program and your internal hard drive plummets to below 10% (or less than 5GB of internal storage), Time Machine will delete all local snapshots except the most recent. The program will then continue to replace the old snapshot with a new one until you free up space on your Mac's internal storage, at which point it will go back to saving weekly snapshots as long as space permits.

That being said, everything doesn't always work properly and you may find yourself out of storage space on your internal hard drive, and those snapshot backups just won't go away. If you really need to delete those snapshots (which I don't recommend unless you desperately need that space), there is a way to purge local snapshots from your internal hard drive. You can use a Terminal command that will disable Time Machine's local snapshot feature, which will delete all of the local snapshots on your internal hard drive. It will also stop Time Machine from creating new snapshots.
To disable local snapshots in Time Machine and remove them from your internal storage:
- Open Time Machine Preferences from the Time Machine menu in the menu bar on your Mac.
- Uncheck Back Up Automatically.
- Wait a few minutes for the local snapshots to delete.
Check Back Up Automatically again.

Any questions?
Before you decide to purge your local snapshots, be sure you really need to do this. Time Machine should work automatically to remove older backups as you need the storage space on your internal hard drive. If you delete old backups, you can never retrieve data from them if something were to go wrong while you aren't connected to your backup hard drive. If you have any questions about local snapshots, drop them in the comments, and I'll help you out.

Have you ever accidentally deleted a file or folder from your Mac that was very important to you, such as your genealogy data files or your Great American Novel in progress? It’s truly a painful experience. You can avoid that heartache with an inexpensive USB flash drive and a little preparation!
This process is a “down and dirty” backup because it doesn’t protect your entire system automatically, the way El Capitan’s built-in Time Machine backup system does. It’s much cheaper than buying an external 1TB USB hard drive, however, and no setup is involved. Computer owners have been using this simple trick ever since the invention of the floppy disk. If you do decide to use Time Machine, you’ll find complete instructions on setting things up in the El Capitan Help system. Remember, you need to buy an external USB or Thunderbolt hard drive to use Time Machine!
If you don’t already have a USB flash drive handy, drop by your local electronics or computer store and buy one. Make sure that the drive you choose is labeled as being compatible with Mac OS X and that it provides at least 32GB of storage capacity.
Then you can use your USB flash drive to back up your important files, as follows:
- Plug the drive into your Mac’s USB port.
The drive should appear on your Desktop and in the Devices section on the left side of any Finder window. - Drag the files you want to back up to the USB drive icon in either location.
You can drag one file at a time or an entire folder’s worth of files.
With a “down and dirty” backup, you’re copying only those files that you absolutely can’t afford to lose. - When you’re done copying files, eject the flash drive by right-clicking the flash drive’s icon and choosing Eject from the pop-up menu.
Store that drive in a safe location. Repeat the process again as necessary to “freshen” your backup files.
Restoring a file is as easy as plugging in the flash drive and copying the files back to your Mac’s hard drive.

Have you created an Apple ID/iCloud account? If so, it’s also possible to back up those same essential files to your iCloud Drive instead of a USB flash drive. Instead of dragging the files to an external drive, drag them to the iCloud Drive entry at the left side of the Finder window. There are two caveats with iCloud Drive storage: first, there’s a set limit to the total capacity of your iCloud Drive (typically less than 5GB). Also, if you’re unable to log in to your iCloud account — either on your Mac or another person’s Mac — you can’t access those files.
