Hi
(moved from Windows Server TechCenter > Windows Server Forums > Windows Server 2012 General, unable to get a response)
Several weeks ago i believe i saw a web article stating that if a compressed folder on a drive is uncompressed, and dedup is enabled, deduplication will not kick in. Unfortunately i did not record the URL and now i can't find the article..
=> Is this correct ?
Some context :
- 2008 R2 server to be upgraded to Server 2012
- We have some volumes with large areas with NTFS drive compression on (we were running out of space)
- some of these areas have high repeat file counts so would be suitable for deduplication but a catch 22 exists in that i have limited space to uncompress them
- IF i could uncompress folders and dedeuplication kicked in, then i could afford to do chunks over many weeks until all the compressed folders are uncompressed
So you can see why it is important i get the correct answer.
I am guessing this work flow should work :
- copy compressed folders (drive A) to spare volume as uncompressed folders (drive B)
- delete the compressed folders on drive A
-Copy folder on drive B back to drive A ?
Thanks
