Restoring a project from backup
Every time you start STx, the current project is backed up to the folder backup in the STx root directory. Should you need to restore a backed up version of a project file, choose Backup / Restore from the Special menu in the Workspace.
You can set the number of backups to keep in the log settings dialog.
Note that even if your project file is linked, all the sound file metadata available in STx is saved to the backup file.
