Zmanda's deduplication offers you a seamless way in which you can transfer and store data by recognizing and avoiding duplicate units of data at the file level or block level during backups.
Zmanda’s file-level deduplication works at the file level by eliminating duplicate files; block-level deduplication works at a block level (which may be a fixed-size block or a variably sized block) by eliminating duplicate blocks.
With Zmanda’s file-level deduplication is that it takes less resources and thus it gets deployed over larger amounts of physical storage. With the advantage of Zmanda enabling block-level deduplication is that it can eliminate chunks of data smaller than a file.
Zmanda’s deduplication feature can be a game-changer, saving hundreds of thousands of dollars on petabyte-scale backups.
