The update command deleted the remote binary before uploading the new one and took no backup, so a deploy that failed half way left nothing to roll back to. Previous production deploys made a predeploy-<stamp> directory by hand. Each target now gets that snapshot automatically before anything is replaced: the service binary and its companion (scanner with hold, labeler with appview), their configs and systemd units, the vcs.revision of each old binary, and for the appview a sqlite3 .backup of ui.db because migrations run on the next boot. A backup that does not complete aborts the deploy. The newest five per server are kept; --backup-keep changes that and --skip-backup turns it off.
