I had an OLD FileServer, WIN2012R2, 3 TB Volume with Dedup enabled and average rate of dedup it was 49%-52% over tha last 3 years. IN 2016, the free space of the volume is going down and in january we had 10% freespace and yesterday it was less than 1% of free space on the old file server last week
We bought a new FileServer, Win2012R2, 10TB volume and i´ve migrated all 5.5 MILLION of files this week
Now the dedups saving rates is 72%!!!!!!!!
If the files are the same in both volumes, how could the saving rate grown up so much?
Maybe because there is more disk space avalable?
What i was expecting is the same saving rate for both servers, because the set of files and folders were the same. But after a week preparing the migration, copying files 2 weeks ago in full mode and in the last 5 days doing incremental copies, why does the saving rate is so higher than earlier?
