Currently, I am using a RAID10 ZFS array composed of 12 4TB enterprise-grade hard drives.
The backup speed is satisfactory and meets my requirements.
I have found that processing and verifying backups takes a considerable amount of time, nearly 20 hours each time.
I want to know what determines the performance of backup verification? Is it sequential read/write or random read/write?
If ZFS RAID10 does not improve the speed of backup verification, can I try setting up multiple RAID1 arrays?
For example, I could change my current 12 4TB hard drives from RAID10 to 6 RAID1 arrays.
