Ignore backup disk?

Hi,

I know that I found somewhere on this forum the way to force Hazel to ignore backup disks, but I can't find it. When I trash an application, App Sweep does not engage because the application is still "installed" on the bootable backup disk I maintain using Super Duper. If I unplug the backup disk, App Sweep works, but then when the disk is remounted, App Sweep tells me that the app was reinstalled and offers to replace the support files. Obviously I can say no every time, but it would be easier if Hazel just ignored that disk.

Any advice would be appreciated. Thank you.

It's a hidden default as described in this post: viewtopic.php?f=3&t=415

Thank you! So to clarify, Hazel will continue to ignore my Time Machine back up and all I need to do is paste the following command into Terminal on my Mac, where I have substituted the name of my Super Duper backup volume for dir1 and deleting dir2?

defaults write com.noodlesoft.Hazel IgnoredBackupDirs -array SuperDuper\ Backup

Yes, Time Machine backups are automatically ignored. Your path doesn't look right there, though. Navigate to it in Finder and drag it into the Terminal window. That should give you the full path.

It worked perfectly, and you were right about the path not being correct. It should have been:

defaults write com.noodlesoft.Hazel IgnoredBackupDirs /Volumes/SuperDuper\ Backup

Thank you!
