Time Machine Backup


Time Machine Backup

Time Machine is the built-in backup feature of OS X that works with your Mac and an external drive. Connect the drive, tell Time Machine to use it, and relax. Time Machine autonatically backs up your entire Mac, including system files, applications, accounts, preferences, email messages, music, photos, movies and documents. But what makes time Machine idfferent from other backup applications is that i not only keeps a spare copy of every file, it rememvers how your system looked on any given day-so you can revisit your Mac as it appeared in the past. Time Machine keeos hourly backups for the past 24 hours, daily backups for the past month, and weekly backups until your backup drive is full.

OSX Lion (10.7 and later) lets you:

  • Encrypt your Time Machine backup

OS X Mountain Lion (10.7 and later) let you:

  • Encrypt AirPort Time Capsule backups and network backup
  • Select multiple destinations that Time Machine will rotate through backup cycles
  • Complete backups when the Mac is in Power Nap (on compatible Macs)

OS X Mavericks (10.9) lets you:

  • Stay informed of your initial backup status using notifications. Time Machine displays a notification after the first backup is complete, or if any issues arise during the initial backup.
