Darksurf Posted July 5, 2022 Share Posted July 5, 2022 So its been a dream of mine to get an LTO Tape Drive one day and run backups. In reality, my wife will never let me spend that kind of money for a drive. HDDs on the other hand are far cheaper for the same amount of storage (~30T). So I've been upgrading my cute Original WD Red 3T drives to Seagate EXOS 3x14T and 3x8T drives. But newer larger drives don't exactly have the same level of reliability in my experience in Datacenters. So I'd like to make use of the extra drive bays I'm freeing up. I have 12 bays. I plan to use 6 for my array with dual parity. I'd like to use the other 4-6 bays for a weekly backup. Evidently you cannot create 2 arrays in Unraid so my 2nd Array for weekly backup idea isn't going to work. What do you recommend here? Should I just create a "pool" for backups with no parity? should I risk BTRFS RAID6 pool as a backup solution, or just go the more expensive route to BTRFS RAID10 pool? Something else? The server is on a 1500Watt UPS. Risk of unclean shutdown is low. writes would only be weekly and incremental. No need to completely rewrite the entire backup. Quote Link to comment
