MAC

Mac has software already integrated into the computer called TIME MACHINE. For this program to be in effect, you require an EXTERNAL HARD DRIVE. If you are in need of backing up your computer and do not have an external hard drive, google “external hard drive” to begin finding one at a price that best suits you/

When you connect an external hard drive directly to your Mac, you might be asked if you want to use the drive to back up with Time Machine. Select Encrypt Backup Disk (recommended), then click Use as Backup Disk.                                                                                                

Otherwise, follow these instructions

1. Open Time Machine preferences from the Time Machine menu  in the menu bar. Or choose Apple   menu > System Preferences, then click Time Machine.
2. Click Select Backup Disk, Select Disk, or Add or Remove Backup Disk.
3. Select a backup disk from the list, then click Use Disk.
4. For additional backup security and convenience, you can repeat these steps to add another backup disk. For example, you might use one backup disk while at home, and another backup disk while at work.                                                                                                                                                                                             

After you set up Time Machine, it automatically makes hourly backups for the past 24 hours, daily backups for the past month, and weekly backups for all previous months. The oldest backups are deleted when your backup disk is full.

• To back up now instead of waiting for the next automatic backup, choose Back Up Now from the Time Machine menu .
• To stop automatic backups, open Time Machine preferences, then either deselect Back Up Automatically (macOS Sierra or later) or turn off Time Machine (OS X El Capitan or earlier). You can still back up manually by choosing Back Up Now from the Time Machine menu.
• To cancel a backup in progress, choose Skip This Backup (or Stop Backing Up) from the Time Machine menu. 
• To check backup status, use the Time Machine menu. The icon shows when Time Machine is backing up , idle until the next automatic backup , or unable to complete the backup .
• To exclude items from your backup, open Time Machine preferences from the Time machine menu, click Options, then click  and select the item to exclude.  

Your first backup may take a long time, depending on how many files you have. You can continue using your Mac while a backup is underway. Some Mac computers make backups even when asleep. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.

Recovering your mac.

To completely restore your Mac, use the “Restore from Time Machine Backup” utility in macOS Recovery. The disk you’re restoring is erased before receiving the macOS (Press cmd+R when powering up your computer) and other contents of your Time Machine backup.
