Vishesh Gupta Posted July 17, 2023 Share Posted July 17, 2023 The main UnRaid array consisting of 20 SSDs of 1TB each with 2 parity drives. Total 18 TB. A ZFS pool with 3 x 10TB HDDs in RaidZ1 config, giving a total of 20TB. I would like to have incremental backups from main SSD array to the HDD pool. How can I achieve this? The purpose:- 1) To have a mirrored backup on HDD for long term storage 2) The SSD array would always be mounted with read / write permissions, whereas the HDD pool will never be mounted and just be used as a backup. 3) The ability to roll back on a previous version of backup incase of a ransomware attack. Am I overthinking? Quote Link to comment
