Whenever you connect an external drive to the USB port of Mac, you will see an alert asking if the drive to be used to take back up with the Time Machine. You will see ‘Decide Later’, ‘Don’t Use’ and ‘Use as Backup Disk’ options. If you select the option ‘Use as Backup Disk’ and if that is encrypted, then all backups will be accessible for the users with the correct password entered only.

4. First backup takes a long time depending on the number of files.
5. The Time Machine takes backup of files that are changed since from the previous backup and hence the future backups would be much faster.

If the Time Machine storage becomes full, then a new backup cannot be stored. It starts deleting the oldest backups to make more space available for new backups. For example, if the Time Machine is first activated in 2014 and the disk gets full today, then those first backups from 2014 will start to disappear.
