What can you back up with Time Machine?
Time Machine lets you back up your entire Mac, including system files, apps, music, photos, emails, and
documents.
How does Time Machine maintain a backup history of the file system?
Time Machine saves space by ignoring files that don’t need to be backed up—ones that can be recreated
after a restoration. Generally speaking, Time Machine ignores temporary files, Spotlight
indexes, items in the Trash, and anything that can be considered a cache. Software developers can also
instruct Time Machine to ignore specific app data that does not need to be backed up.
Which types of files are omitted from Time Machine backups?
Time Machine is inefficient at backing up large databases because it must back up the entire database
file every time any change, no matter how small, is made to the database.

Plus, Time Machine offers to reformat it into the supported format of HFS Plus.
Which feature helps Time Machine restore data when your Time Machine backup disk isn’t available?
