What is the recommended method to backup data to an offline build without regular update?
I thought about building a system with 1 HDD only No-RAID, taking advantage of ZFS or BTRFS metadata and data integrity checksum to avoid bitrot or other factors that may affect the written bits. Can FreeNAS do a scrub and fix errors using only metadata and checksum?
If it will not work, I may just do a RAID1 4TB+4TB using WD BLUE drives, and when a drive hangs due to TLER I'll just restart it manually. Maybe I have it all wrong... what do you think?
