Backup Copies
Automatic Backups
Logic will ask you if you wish to make a backup copy of the file you’re working on
(unless one already exists), before you perform a destructive edit in the Sample Editor.
Activate the No Dialog button to avoid this question being asked again, while editing in
the current window.
You can even turn off the dialog altogether in the Audio > Audio Preferences. In this
situation, you’ll only be asked when the program is first loaded, and when you make
your first edit. You can reply as follows:
Process
No backup is made and the edit is performed. You won’t be asked the question until
the next program launch.
Cancel
Stops the edit.
Preferences
Opens the Audio Preferences window, allowing you to reactivate the Backup dialog
box, so that it appears every time you attempt a destructive edit.
Manual Backups
You can make manual backups of the file you’re editing, or replace it with a backup
version at any time—using a variety of functions:
Audio File > Create Backup
Creates a duplicate of the audio file you’re working on (with the extension “.dup”), and
places it on the same level, in the same folder.
Audio File > Revert to Backup
This function completely replaces the current audio file with the backup (provided one
exists, of course). A warning message informs you of the creation date of the backup
file, before the current file is replaced.
You cannot reverse this function with Undo.
Audio File > Save A Copy As
Copies the current audio file to the location of your choice.
Audio File > Save Selection As
Saves the current selection as an independent audio file. You can choose whether you
wish to bring the file into the Audio window, following the save.
An interleaved stereo file is created when the source file is an interleaved stereo file.
