Apple Keynote '09 - Manual (Page 34)

The best way to create backup versions is different, depending upon which version
of Mac OS X you’re running. Mac OS X v10.7 (Lion) and later automatically saves a
snapshot of your presentation every time you save. You can access an archive of
all previous saved versions at any time. To learn about accessing and using past
document versions in Lion, see “Finding an Archived Version of a Presentation” on
page 34.
If you’re running Mac OS X v10.6.x (Snow Leopard) or earlier, you can set up Keynote
to automatically create a copy of the last saved version of your presentation. You may
also find this useful if you’re running Lion, and you want to save a backup version of
your presentation on another hard disk on your network.
To create an archive of previously saved versions of your presentation on Lion
or later:
Choose File > “Save a Version,” or press Command-S.
m
To create a copy of the last saved version of your presentation:
Choose Keynote > Preferences, click General, and then select “Back up previous
m
version.”
The next time you save your presentation, a backup version is created in the same
location, with “Backup of” preceding the filename. Only one version—the last saved
version—is backed up. Every time you save the presentation, the old backup file is
replaced with the new backup file.
Finding an Archived Version of a Presentation
If you saved archived versions of your presentation on Mac OS X v10.7 (Lion) or later,
you can browse the archive to identify any earlier version that you want to restore
or reference. After you identify the archived version that you want, you can restore it
as a fully editable copy, or you can just extract from it any text, images, or document
settings that you want to use again.
To browse archived versions of your presentation:
1 Open the presentation for which you want to access older versions, and hold your
pointer over the name of the presentation at the top of the Keynote application window.
A triangle appears.
2 Click the triangle and choose Browse All Versions.
