Data Hoarder

Hello all, I have a brainstorming question for you all, or maybe I'm just looking to confirm that my proposed solution makes some sense.

I am looking to re-arrange my storage solution to fit my needs, here is the situation:

• I have a 2TB iCloud drive which is the main source of data (iCloud drive and Photos).
• I have a self hosted Jellyfin instance that requires storage for the media content.
• At the moment it's using a 2TB WD Element USB drive, which is terrible, not enough storage and super slow.
• I have a WD MyCloud EX2 Ultra with 2 bays and 2 WD Red 4TB disks.
• I have a TrueNAS machine running on an Atom D2700 with 8GB of RAM and 2 old 320Gigabytes disks that I've used just for testing.

The objective:

• iCloud backup: take a recurring backup of iCloud.
• Jellyfin storage: I figured at least 4TB.
• Reuse and costs optimization: reuse as much of the current hardware as possible and minimizing costs.

My proposed solution:

• iCloud backup:
  • Move the 2x4TB WD Red from the WD MyCloud EX2 Ultra to the TrueNAS machine and set it up in mirror mode.
  • Use icloud-docker to backup iCloud in TrueNAS.
  • Use rclone to keep an additional offsite backup on Scaleway glacier (I'm already using it to store some other backups and very happy with it).
• Jellyfin storage:
  • Buy either 1 or 2 6TB WD Blue disks (or equivalent) to put into the WD MyCloud EX2 Ultra and use that as storage unit for the Jellyfin instance.
  • The reason for using WD Blue is to contain costs. The multimedia storage is not that important to me. Meaning I will not take a backup of it, and if I loose something is not a problem. I just need space and decent speed.
• Reuse and costs optimization:
  • I will reuse all the hardware that I currently have plus buying only 1 or 2 more disks.

What do you guys think?
