From 967763f6ce54316b9708b836d2e64dbf66198686 Mon Sep 17 00:00:00 2001 From: Bryan Van Deusen Date: Mon, 2 Nov 2026 15:26:20 -0500 Subject: [PATCH] feat: the backup can include the music, sending each library file once to music/ and again only when it changes (#6774) With "Include the music" on, each night's run sends the library files the destination doesn't hold yet, after the database file has landed, for up to six hours; a large library spans several nights the first time. Files keep their path under the library folders' common root, beside database/ in the same folder or bucket. backup_music_files records each file's size and mtime as sent, so a night sends only new and changed files, and a rescan that touches a track but finds the same file sends nothing. A changed file goes to its old name; Minstrel never deletes there. An object the bucket refuses (a locked overwrite) is kept with its answer and goes again once the file changes or the settings are saved; three refusals in a row stop the night's music, since that is a key that may not write under music/. A folder copy is written under a .part name and renamed, keeping the file's time. The panel shows how much of the library is in, the refused files, and each run's music count and note. The verdict still turns on the database file.
