De-duplication on Storage Server 2008 R2

[rsutoratosu]

Anyone use or tired storage server 2008.. Just wondering how the de-duplication would work on image files. I do have several image under the same name, different folder. Wonder if it's going to delete one or something.

I have tried de-dup on vmware vm and they save up to 30% on space, I imagine getting rid of the white space, etc. But not sure how the storage server would work out.

The Single Instance Storage (SIS) feature in Windows Storage Server 2008 R2 appliances provides file deduplication by actively comparing and eliminating identical files on volumes to optimize storage capacity. Duplicate files are transparently replaced with file system links to the single copy retained in the SIS Common Store, which increases the efficiency of disk utilization. In addition, protection and recovery by SIS-aware backup solutions can also reduce the time to perform backups and disaster recovery.

Sounds like it will indeed delete one of them and replace it with an NTFS hard link so you shouldn't notice any difference in usage of the files. Kinda sucks that it's at the file level and not the block level, but it's better than nothing I guess.

When you say image files... what kind?

Deployment server uses SIS for WIM files. If you want to save some space you can try compressing the images also.
