How to backup hard drive on mac

You don¡¯t really understand the importance of backup hard drive until your hard drive crashes. With most backups, you¡¯ll need to reinstall the operating system and then restore all of your data. OS X comes with a handy tool that will let you create a live copy of your hard drive that can be started up and run just like it is your computer.

This feature is part of the Disk Utility application stored in your Application > Utilities folder. It is simple to use, but you have to pay attention to make sure you are copying your data in the correct direction¨Cyou don¡¯t want to accidentally copy an old backup over your working data.

1.When you launch Disk Utility, it will show you a list of the available drives on your computer.

In the right hand side of the application, select the Restore tab. This will make the Backup partition into an exact copy of your local drive¨Ceven changing its name.

2.With the Restore tab selected the local drive into the source and backup into the destination and erase the destination.

At this point you can double check carefully to make sure your source and destination are correct and accidentally going to overwrite important data.

3.Clicking on the Restore button starts the process.

It isn¡¯t particularly fast. You should make the partition you are restoring to as close in size to the original in order for the transfer to be as efficient as possible.

Tips: If you ever need to bootup the drive on another computer, you have to make sure that computer to start using the external drive as the startup drive first.

Once you reboot the system, it should boot up using the external hard drive as if it is the system you backed up originally.

To restore from your hard drive, you¡¯ll simply perform the restore process, but this time moving the data from your external drive back to your computer¡¯s internal drive.
