I have 2 copies of the same data in separate HDDs. Which copy should I use to create the 3rd one?
Otherwise check out Hashdeep: https://github.com/jessek/hashdeep/

DS 415 play in 2022
I use hashdeep. You have to install ipkgui on Synology and then md5deep through that which includes hashdeep (or just use md5deep). You can read up on hashdeep/md5deep here in the docs folder: https://github.com/jessek/hashdeep/

How do I manage years of data?
Started to be able to bring some order after I discovered hashdeep. Basically I started from a reasonably clean disk with folders to sort files, created lists of hashes using hashdeep, then used it to scan all my existing disks for unknown files. With the correct flags hashdeep can list all files it finds on a disk that it has not in its lists already. That help a lot to figure out what is worth wasting time on. It also is useful because every now and then that makes me realize the copy of some old file I have is broken (probably usually because it was stored on some CDROM that was no longer good).

Storage software with the features of Unraid but runs on Debian with cli interface?
Would mergerfs and snapraid work for you? You'd sacrifice a disk to parity and run the parity calc manually, but you could set up a cron job for that.

If you are using OpenMediaVault, checkout SnapRaid plugin.

Does this count?
I used drivepool for years with snapraid before I switched over to unraid. Nothing but good things to say about either program. Highly recommend both.

Merge/Raid HDD documentation
You can always use SnapRAID . there is no user interface, it is CLI. also you have to sync it manually. or set up a cronjob. you loose a hdd like unRaid or RAID5 but it gives you parity. then you could always use duplicati and backblaze business to make backups. it isnt as expensive as you would think for a homelab. the first back up might be a little much but then its pennies after that

Converting my old pc to a backup solution
As for the drives I'm thinking of grabbing a few from ServerPartDeals and upgrading my setup that uses DrivePool and snapRAID, but in Linux you would use mergerfs instead of DrivePool.

Thinking of switching from a 4 bay hardware RAID 5 to an 8 bay JBOD. Looking for opinions.
I myself prescribe to the teachings of the IronicBadger(Alex Kretzshmar) from the Self-Hosted podcast and (when I get one setup) intend to follow the guides on his site https://perfectmediaserver.com and use mergerfs to turn a JBOD to a single filesystem and use SnapRAID for redundancy.

WWYD? Help choosing b/w NAS, DAS or micro PC case?
I have that exact Sabrent 5 bay enclosure and I replaced it with this Orico 5 bay enclosure because the Sabrent's connection would fail while I ran snapraid sync, but the Orico has never failed me.

Just ordered 2 20TB CMR HDD’s and I’m extremely excited. What RAID method should I use?
With two drives? Just run them as-is. Once you get a third disk, set up https://www.snapraid.it. Then as you add more, just follow https://www.snapraid.it/faq#howmanypar to have the correct number of parity disks. Or don't, Plex content is probably easy to re-acquire if you need to so having redundancy or a backup isn't all that important.
What are some alternatives?
RHash - Great utility for computing hash sums
Elucidate - Elucidate: A GUI to drive the SnapRAID command line (via .Net)
k4dirstat - K4DirStat (KDE Directory Statistics) is a small utility program that sums up disk usage for directory trees, very much like the Unix 'du' command. It displays the disk space used up by a directory tree, both numerically and graphically (copied from the Debian package description).
