I don't get it - many people here claim in this thread that VM base image deduplication is great use case for this. So lets assume there are couple of hundreds of VMs on a ZFS dataset with dedupe on, each of them ran by different people for different purposes entirely - some databases, some web frontends / backends, minio S3 storage or backups ect - this might save you those measly hundreds of megabytes for linux system files those VMs might have in common ( even though knowing how many linux versions are out there with different patch levels - unlikely ) it will still not be worth it considering ZFS will keep track of each users individual files - databases and backup files and whatnot - data which is almost guaranteed to be unique between users so it will completely miss the point of ZFS deduplication. What am I missing?
