I can’t speak to Synology’s implementation but perhaps a glimpse down the rabbit hole of the Linux file system will give some insight into backups, deduplication, and incremental synchronization techniques. I know this post is long as hell, and I’ll appreciate any feedback. Will I have on BB BackupSet1.hbk and BackupSet2.hbk and BackupSet3.hbk each containing Song1, Song 2, and Song 3, or will there be only one copy of each song on BB and some sort of “virtual shortcut” that’s used to save space on the backup? Note: I keep BackBlaze “dumb”: I don’t let it control versioning, I don’t let it control deleting older files etc - I have Synology HyperBackup control all of that. Now, when my different HyperBackup backup sets fire off, is Synology DS920+ making multiple copies on the BackBlaze B2 bucket? (I have one bucket, and multiple HBK backup sets on BB). Let’s also say that I’ve got multiple copies of each scattered around (some in my old laptop backups, some in my Plex Media folder on the NAS, etc)> Here’s the question: Let’s say that I have some music files, Song 1, Song2, and Song3. I break down my backups : one set for Plex Media, one set for Family Photos/videos, one set for data backups from my laptop/phone, etc. Let’s say I have a Syno DS920+ with two 10TB drives mirroring each other.
Tell me this, all wise folk who are reading this: It’d be great if Synology issued a white paper, but whatever. I’m trying to figure out how HyperBackup precisely works.
(I did try searching on this, but no luck)
