Once you have selected the items you wish to include click OK. Choose a name for the session copy as well as where you would like the copy to be created. Press Save to begin the process. A pop-up window should appear showing the progress of copying the files. This process may take a few minutes depending on the size of the session. The size of a session is determined by its sample rate, number of tracks, length, complexity of the session settings and other media assets. By the way, an added benefit of using Save Copy In is that it only copies the files that are actually used in the session. Any abandoned files that happen to be in the audio files folder are not included. Therefore, using Save Copy In may provide a bit of clean-up, reducing the size of the new session compared to the original.
After the copy is finished, it's a good idea to test it. If possible, eject (unmount) the drive that holds the original session. You can take it a step further and completely unplug and unhook the drive if you wish. Once the original session drive is disabled, open the session copy watching for any errors or missing files warning pop-ups. Briefly examine the tracks for any grayed out regions (which means Pro Tools can't find them), then test the playback.
Alternately, manually check the session's Disk Allocation from within Pro Tools. To do so, open the new session backup copy, then view the Disk Allocation under the Settings menu. Scroll through the tracks checking the path for audio files. You can also view the location of the audio files from the Regions Bin. Under the Show menu under the pulldown menu at the top of the Regions Bin, choose Full Path. Follow the system hierarchy (OS X or WIndows) to determine where the audio files reside. By the way, if the session has grayed out regions, you can use this method to find out where Pro Tools thinks the region's audio files should be.
In summary, our Pro Tools tutorial explains how using Save Copy In can help ensure your Pro Tools session backup is complete with all necessary media files. Using this feature for session copies may also shrink the resulting copy's folder size. As a third benefit, Save Copy In allows you to change the file type, sample rate and bit depth for the copy.
Note: Making a copy onto the same drive is not recommended as a safety copy. This may be useful for clean-up purposes, but if the drive fails you may lose both copies, even if the drive is partitioned. Session backup copies should be stored on an entirely different drive or other storage media.
