Bitrot Qnap Ext4
Looking for a long term cold storage (the data is not used actively anymore) option for about 30TB of data and was looking at QNAP RAID 6 option as base for this backup. (I will have individual 3 x 10 TB drives offsite as well (2 off site locations)). I know the Raid 6 will give me drive failure protection, but activating scrubbing, will that be the best option for super long term storage and protection of data corrosion? Plus, if I power this NAS down, how often should I power it up to perform this scrubbing?
My real big concern is data loss from bitrot over long periods of time.
