At this time, Chronicall has no functionality to backup recordings. If you want backups of the audio files, you must copy the files manually to your backup location. You can find the storage location of the files in the Recording Library settings
The recordings are located in the "0" folder in the storage pool path. The file structure is very important to the process Chronicall uses to recall recordings. To preserve it, the best option is to copy the entire "0" folder to your backup location.
Recordings are also dependent on our database, so it's always a good idea to schedule regular database backups.
