If you keep backups on time machine you can browse these backups from a different mac.

there is a little trick to it, but its simple once you master it :)

if you click on the time machine icon in the menu bar then the time machine menu will appear.

if you look at the ‘enter time machine’ entry and press the ‘alt’ key then the entry will change to ‘browse other time machine backups’

if you click the browse other time machine backups’ menu then a dialog will open with a list of the backups stored on your time machine.

just click the backup volume you want to browse.

currently its only available on a mac (its near impossible to browse a time machine backup from a windows or linux machine)
