Automatic backups

Everything (log, operators, the message in Compose) is saved in this browser as you type. On top of that:

Snapshots in this browser — taken automatically every few minutes while you work (the last 30 are kept). Restore one below.
Backup folder — pick a folder (a USB stick, or a OneDrive folder so it syncs) and a backup file is written there automatically: MessageLog_backup_latest.json after every change, plus a dated copy at the interval below. Needs Chrome or Edge.

Dated copy every min

Backup and restore by hand

Restore from a backup file…

A backup file holds the whole log, the operators and the log header. Restoring replaces what is here now (a snapshot of the current data is taken first).
