Figure 7-4. Opening Time <strong>Mac</strong>hine while Mail is running in the foreground opens Time <strong>Mac</strong>hine in<br />

Mail, allowing you to recover deleted Mail messages.<br />

If you ever need to recover more than just a file or a few e-mail messages, Time <strong>Mac</strong>hine<br />

allows you to select and recover entire folders, or, yes, even your entire volume. Additionally, if<br />

you even have to reinstall your system from scratch, there is an option during the install that will<br />

recover information from a Time <strong>Mac</strong>hine backup disk (you can learn more about installing<br />

<strong>Leopard</strong> in Appendix B).<br />

NOTE Many people may point out that Time <strong>Mac</strong>hine actually goes beyond just backup and<br />

actually provides version control as well. Version control tracks changes of items over time so<br />

that you can recover older versions if something critically wrong happens in a new version. For<br />

developers, version control (or source code management [SCM]) is essential for creating stable<br />

software, and support for a number of version control systems including CVS, Subversion, and<br />

Perforce are built into Xcode. For more general project version control, Versions (www.<br />

versionsapp.com/) provides an easy-to-use interface for taking advantage of the Subversion<br />

version control system.<br />

Synchronization<br />

CHAPTER 7 BACKUP, SYNCHRONIZATION, AND RECOVERY OF DATA 139<br />

Besides backup, <strong>Leopard</strong> provides a number of ways for you to sync your data with the other<br />

computers or devices you use.<br />

First there is iSync (Figure 7-5). iSync allows you to sync your calendars and your contacts<br />

with mobile devices. So if you are out and about and meet an old friend and enter their contact<br />

information in your phone, next time you sync your phone using iSync, that contact information<br />

will be added to your Address Book. At the same time, if you add a number of events in iCal,<br />

when you sync your phone with iSync, those events get entered into your phone’s calendar.
