RAID is not a backup.
- georgyo 2y agoAgreed, raid is not backup. But restoring 50TB of data from actual backups take a lot of time. I like BTRFS to a fair degree, but thae fact that _any_ two drives failing in its "raid 10" configuration causes data loss is not obvious or intuitive.
- 28304283409234 2y agoIf one has 50TB(!!) of mission critical data, one should not store it on one machine running btrfs. That is just silly. No many how many mirrors you throw at it.
- timc3 2y agoIt sounded to me more like the system was being used for Backups, not that they expect RAID to be a backup.
