Main server: ASUS RS520A-E11-RS12U, Epyc 7413, 128GB ECC, 2x WD Black SN770 (mirrored boot), 4x WD Black SN850X (docker, downloads, cameras), 6x WD Ultrastar DC HC580 24TB (RaidZ2)

Notes:

  • Backup will sync using ZFS tools on a daily or weekly basis. While not in use drives will spin down.
  • Hoping to connect from home to offsite location using tailscale to sync
  • Backup size is indeed smaller than main. New 6x 24TB drives will go into the main server and old 18TB drives will go into the backup. Currently 36TB in use, so still fine. Might cycle again in the future if the backup nears 100%. 6 unused bays in the ASUS chassis for now. Other approach could be to put largest drives in backup and increase main server with 6 new disks in the future.
  • Main goal was to keep the backup lightweight, silent and power efficient
