I'm editing (large) photos in Lightroom, and have just added a Synology NAS. I'm not interested in the NAS for processing or sharing photos, only for recovery of data. The NAS has 1gb ethernet, so (from the latest photo video) I wouldn't try to edit from the NAS, but would sync or backup the lightroom pictures and directories. I'm concerned that NAS "helpful" processing such as creation of thumbnails & AI processing could modifiy or add something in the lightroom folders that would cause problems with recovery when restoring the data. Would a variety of sync or of backup be better, and is there a way of being sure the NAS doesn't modify the data?
