Auto-save & backups

LTCast runs two separate protection systems to guard against data loss: an auto-save that writes the current session continuously, and a timestamped backup system that creates restorable snapshots at a configurable interval.

Auto-save

LTCast saves the current state of your project automatically throughout the session. This is separate from the named .ltcast file you manage with File → Save. If the app crashes or the computer loses power, the auto-save is used to recover your work on next launch.

Auto-save happens in the background and does not interrupt playback. There is no configuration required — it is always active.

Timestamped backups

In addition to auto-save, LTCast can create timestamped copies of your .ltcast file at a regular interval. 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.

Configuring backups

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

Auto Backup — toggle to enable or disable timestamped backups
Interval — how often to create a new backup, in minutes; the default is 10 minutes
Keep last N — the maximum number of backups to retain; when the limit is reached, the oldest backup is deleted to make room for the new one
Open Backup Folder — click to open the backup location in your file manager; backups are stored in an application data folder, not alongside your project file

Restoring a backup

To restore an earlier version of your project:

Click Backups… in the toolbar, or go to Settings → System → Backup
Select a backup from the list; each entry shows the date, time, and project name at the time of the backup
Click Restore; LTCast confirms before replacing the current project
The restored project opens in the same state it was in when the backup was created

Backups capture the project file only — not the audio files. Audio files must still be present at their original paths (or re-linked) after a restore.

Backup storage location

Backups are stored in the LTCast application data folder, separate from your project files. This means backups survive if you delete or move your .ltcast file, but they do not survive if you uninstall LTCast and remove application data. For long-term archiving, use Collect Project instead.
