Mac OSX：当Time Machine备份时禁止Spotlight

下面是一个实用的例子，用来说明如何禁止和启动Spotlight服务，他适用于OS X 10.5 Leopard系统：
它的目的是，因为在Time Machine备份数据的时候，Spotlight默认是索引所有的Volume上的数据，这样他干扰了Time Machine的备份工作，使工作变慢。
它的用法是，把/System/Library/CoreServices/里面的backupd服务程序改名，然后用下面的script代替
mdutil -i off /Volumes/backup
./new-name-of-backupd
mdutil -i on /Volumes/backup


*****************************************
Disable Spotlight during Time Machine backups
Running a daemon every minute seems like overkill. Why not rename /System/Library/CoreServices/backupd and install a script in its place:

mdutil -i off /Volumes/backup
./new-name-of-backupd
mdutil -i on /Volumes/backup

That should turn off spotlight indexing immediately before backupd runs, and turn it back on when the backup is finished.
