You can use Time Machine, the built-in backup feature of your Mac, to automatically back up all of your files, including apps, music, photos, email, documents, and system files. When you have a backup, you can restore files from your backup if the original files are ever deleted from your Mac, or the hard disk (or SSD) in your Mac is erased or replaced.
Jan 17, 2020 Time Machine runs every hour. If for some reason, your Mac is asleep or the external hard drive cannot be reached, Time Machine will reinitiate the backup as soon as it can. As long as the backup hard drive can be found, Time Machine will take care of your data. Why Do I Need Another Backup Software for My Mac? While Time Machine is fast. To many of us, backing up a Mac means setting up Time Machine to make incremental backups and signing up to various iCloud services so that we can keep copies of photos, music, files and more in. In the macOS Utilities window, click Restore From Time Machine Backup. Select your Time Machine backup disk and then the date and time of the backup you want to restore. Select the disk to install the Time Machine backup. The drive will be erased, so make sure.
To create backups with Time Machine, all you need is an external storage device. After you connect the device and select it as your backup disk, Time Machine 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.

When you connect an external 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.
An encrypted backup is accessible only to users with the password. Learn more about keeping your backup disk secure.
If Time Machine doesn't ask to use your drive, follow these steps to add it manually:
If the disk you selected isn't formatted as required by Time Machine, you're prompted to erase the disk first. Click Erase to proceed. This erases all information on the backup disk.
After you select a backup disk, Time Machine immediately begins making periodic backups—automatically and without further action by you. The first backup may take a long time, depending on how many files you have, but you can continue using your Mac while a backup is underway. Time Machine backs up only the files that changed since the previous backup, so future backups will be faster.
To start a backup manually, choose Back Up Now from the Time Machine menu in the menu bar. Use the same menu to check the status of a backup or skip a backup in progress.
