Just curious what people find sufficient really.
RTX 4090 PC: 0.5 TB + 4 TB of M.2 drives. Backed up to Microserver, separate backups to USB HDD too.
A770 PC: 2 TB SSD. Backed up to Microserver.
Microserver: 512 GB SSD + 4x 6TB HDD in RAID 1 (so 12 TB data storage). This gets backed up to an external USB drive. Will probably become a VM on TrueNAS box as HDDs are old.
TrueNAS: 250 GB boot drive + 1 TB cache + 512 GB SLOG + 60 TB data (5x 20 TB RAID Z2). New, so no backup yet.
