I'm using rsnapshot to make backups of a folder which contains audio files. When these files change, it is only metadata such as ID3 tags which change, and I don't need to make a new backup of the entire MP3 file just because of this.
I've got the metadata in a separate database and can easily write that metadata to the files if needed.
Thus, I would like rsnapshot only to make copies of new files and remove deleted files from my backup "vault". My question is; can I simply just use --ignore-existing for this?
Will rsnapshot understand that?
