I am on a DS218+ on DSM 7. I have snapshots enabled for a shared folder that is 19gb in size. I have snapshots enabled for this folder that are taken every 12 hours and 30 snapshots saved. When I use calculate size it shows estimated size to be 4.8gb. However when I login using a terminal I see the size of @sharedsnaps folder is 490gb and each of the 30 snapshots is taking up 19gb, the same size as the original folder. This 19gb folder is the only shared folder with snapshots enabled. The contents of this shared folder is not often changed.
I thought the snapshots are only supposed to be composed of changes and not copies of the entire folder. What is going on here?
