Easy to follow. No jargon. Pictures helped. Didn't match my screen. I was planning to use Robocopy to transfer so this is good news. I'll look into the Inter Packet Gap for Robocopy, I'm transferring over a 1GB connection so this will take quite a large amount of time to complete.

There are several important differences between Data Deduplication and other common storage optimization products:. To optimize a volume, Single Instance Store identified files that were completely identical and replaced them with logical links to a single copy of a file that's stored in the SIS common store. Unlike Single Instance Store, Data Deduplication can get space savings from files that are not identical but share many common patterns and from files that themselves contain many repeated patterns.

With NTFS compression, each file is optimized individually via compression at write-time. This is better than NTFS compression because files may have both internal duplication which is addressed by NTFS compression and have similarities with other files on the volume which is not addressed by NTFS compression. Additionally, Data Deduplication has a post-processing model, which means that new or modified files will be written to disk unoptimized and will be optimized later by Data Deduplication.

How does Data Deduplication differ from archive file formats like zip, rar, 7z, cab, etc.? Archive file formats, like zip, rar, 7z, cab, etc. Like Data Deduplication, duplicated patterns within files and duplicated patterns across files are optimized. However, you have to choose the files that you want to include in the archive. Access semantics are different, too. To access a specific file within the archive, you have to open the archive, select a specific file, and decompress that file for use.

Data Deduplication operates transparently to users and administrators and requires no manual kick-off. Additionally, Data Deduplication preserves access semantics: optimized files appear unchanged after optimization.

Although Data Deduplication provides reasonable defaults for Recommended workloads , you might still want to tweak Data Deduplication settings to get the most out of your storage.

Additionally, other workloads will require some tweaking to ensure that Data Deduplication does not interfere with the workload. Can I manually run a Data Deduplication job? Yes, all Data Deduplication jobs may be run manually. What type of performance hit is involved with this? I ask as its not something I can easily turn off once on. Improve this question.
