The Benefits of Open Source Deduplication
Data deduplication compresses all your redundant data so you can minimize your backup requirements and maximize your storage utilization. So, why backup the same file several times? Here’s how it works- we backup the first bit of unique data and anytime we come across that same piece of data we reference it in a table after that. Reduce 100’s of megabytes to single digits: Deduplication reduces the required storage capacity since only the unique data is stored. For example, a typical email system might contain 100 instances of the same one megabyte (MB) file attachment. If the email platform is backed up or archived, all 100 instances are saved, requiring 100 MB storage space. With data deduplication, only one instance of the attachment is actually stored; each subsequent instance is just referenced back to the one saved copy. In this example, a 100 MB storage demand could be reduced to only 1 MB.
