Hi guys,
I hope this question is answered quickly, but I've been looking for an answer for a while now.
I store on my TrueNAS a Word file which is 403MB. After that I create a snapshot. Afterwards I change the Word file by deleting pages, so that the file is only half the size, 200MB. After that I just save it again.
According to my feeling the snapshot should now grow to about 200MB, because these are the blocks I deleted. However, the snapshot size has grown to almost 403MB. Where is the error in my thinking? I don't understand why the snapshot size not only contains the change but is as big as the original file. If I do the same test with a folder and delete a whole file there, the snapshot grows only by the size of the deleted file. But this does not work with a test file (as described above).
thanks a lot for your help!
