8.07 TiB physically stored on one backup drive holding 174 backups; 11.4 TiB total logical (excluding effects of compression) data on the source; 7.83 TiB hot current logical data on the source (excluding things like ZFS snapshots and compression). Which by your way of calculating seems to work out to an about 246:1 savings compared to simply keeping every single copy in full and uncompressed.
Without seeing a console session, I am unsure what you mean by "physically stored", "total logical (excluding effects of compression) data", and "hot current logical data ... (excluding things like ZFS snapshots and compression)".
What partitioning scheme, volume manager, file system, compression, etc., do you use on your backup server?
I had thought you were using rsnapsnot/ rsync --link-dest, but you also mention ZFS snapshots. Please clarify.
