Auto-save & backups

LTCast runs two separate protection systems to guard against data loss: an auto-save that writes your show file every few minutes, and a timestamped backup system that creates restorable copies at a configurable interval.

Auto-save

If the show has a file and unsaved changes, LTCast saves it to that same .ltcast file automatically every 5 minutes and shows an Auto-saved message. The 5-minute interval is fixed — there is nothing to configure — and it does not interrupt playback. A show that has never been saved has no file to write to; the backups below cover it instead.

LTCast also keeps your working session between launches, so if the app closes unexpectedly you come back to where you were.

Timestamped backups

In addition to auto-save, LTCast writes timestamped copies of your show at a regular interval, and once more when you quit. Each backup is a complete snapshot of the project at that point in time. This lets you roll back to an earlier state if you make changes you want to undo, beyond what Cmd+Z / Ctrl+Z can reach. A show that has never been saved is backed up too, once it has songs, into a folder called Unsaved show.

Configuring backups

Open Settings → System → Backup to configure the backup system:

• Auto Backup — toggle to enable or disable timestamped backups; it is on by default
• Interval — how often to create a new backup, in minutes (1–60); the default is 5 minutes
• Keep last — the maximum number of backups to retain per show (1–50, default 10); when the limit is reached, the oldest backup is deleted to make room for the new one
• Open backups folder — click to open the backup location in your file manager

Restoring a backup

There is no restore list inside the app. Backups are ordinary .ltcast files, so you restore one by opening it:

• Click Open backups folder in Settings → System → Backup, and look in the folder named after your show (a show that was never saved is in the folder called Unsaved show); each file is named by its date and time
• Choose File → Open Project… (Ctrl+O / Cmd+O) and pick that backup file
• The project opens in the state it was in when the backup was written
• Use File → Save As… to save it under a normal name. If you press Save instead, LTCast writes back into the backup file

Backup storage location

Backups are stored in Documents/LTCast/Backups, in one folder per show, separate from your project files. This means backups survive if you delete or move your .ltcast file, and because they live in your Documents folder, uninstalling LTCast does not remove them. For long-term archiving, use Collect Project as well.
