I have an old laptop with 500GB that I repurposed as an OMV NAS. I used Docker to run a Nextcloud server, but want to add Letsencrypt, Wiregaurd and Plex in the future. I also purchased an 8TB Western Digital External HDD with USB 3.0 for more storage. Would it be a good idea to reformat my external 8TB to BTRFS and use that as my primary storage space? What are pros/cons of external USB drives as primary storage? What does spin up and spin down matter? It seems like USB has some problems of it's own. What do I need to watch out for?
...My goal is to have a NAS that does incremental backups of all Android, Windows and Linux devices on my wireless network (wired not feasible). There are also files I want to store on the 8TB external that would not be syncing with any other devices on the network, but backed up to a 1TB external drive (individual laptop doesn't have enough space for vacation media). In this manner, I can ensure 2 copies of all my files are at home. I've only glanced at Duplicati and Rsync, but am wondering if sticking with Nextcloud would be ideal. I would also like a way to loop-in my other cloud storage solutions (Google Drive, Dropbox, etc.).
Thanks in advance for the help!
