In other words, redundant copies of a block within the same disk group are reduced to one copy, but redundant blocks across multiple disk groups are not deduplicated. You have to use a token based matching.

Binary Search Tree Structure Based on the comparison i have to decide to merge the contacts automatically or request user attention. file-level deduplication watches for multiple copies of the same file, stores the first copy, and then just links the other references to the first file. lets say we have three users each having 4 data blocks.Green and Gray blocks are common in three users so they backed up in data center.Blue,red and purple block are common between two users hence they backed up in Data center. In addition to that it is possible to compare the contents of files. { How to find list of possible words from a letter matrix [Boggle Solver]. Does my toilet drain poorly because of bad venting? Swapping out our Syntax Highlighter.
Block-level Deduplication, sometimes called variable block-level deduplication, looks at the data block itself to see if another copy of this block already exists. } Found a good example here http://simhash.codeplex.com/.
