RE: cool TM stuff

Or, you can simply modify the correct .plist file: (copy/paste from my post over at MM)

Quote:
The system is certainly easy to configure, but it’s just too simple. After reading a hint at http://www.macfixit.com, I did some hunting around the typically forbidden areas of my hard drive, which yielded some property lists stored in System/Library/LaunchDaemons: com.apple.backupd.plist; com.apple.backupd-auto.plist; com.apple.backupd-wake.plist; and com.apple.backupd-attach.plist. These files can be opened in TextEdit (in your Applications folder), and for my purposes I wanted simply to change the backup interval to every 24 hours. If you open com.apple.backupd-auto.plist in TextEdit, you’ll see this:

{?xml version="1.0" encoding="UTF-8"?}
{!DOCTYPE plist PUBLIC "-//Apple Computer//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"}
{plist version="1.0"}
{dict}
{key}Label{/key}
{string}com.apple.backupd-auto{/string}
{key}ProgramArguments{/key}
{array}
{string}/System/Library/CoreServices/backupd.bundle/Contents/Resources/backupd-helper{/string}
{string}-auto{/string}
{/array}
{key}StartInterval{/key}
{integer}3600{/integer}
{key}RunAtLoad{/key}
{false/}
{key}KeepAlive{/key}
{false/}
{/dict}
{/plist}

To change the interval to every twenty four hours, change the {integer}3600{/integer} line to {integer}86400{/integer} and save the file. The value in that line is the number of seconds between backups. 3600 seconds is one hours, 86400 seconds is one day. Simply save that file, log out, log back in, and you’re all set.


NOTE: the {} = <> and the bolding is mine.

I think I'm going to set both computers to every 12 hours. I did set both my G4 and my wife's Mini to 12 hour intervals. I had to give myself read/write permissions on the LaunchDaemons folder in order to save the changed file, and it requires a reboot (not log out/log in) as stated. The TM PrefPane still shows the hourly backups, but simply doesn't execute them.
