What is De-duplication?
Deduplication is the process of removing
redundant data from any storage medium based upon
identifying repeating components either prior to
or shortly after writing to the media.
Deduplication is used primarily on Backup and
Archived data as this data contains the most
redundancy, is the least performance sensitive
data, and consumes the most media capacity in a
data center.
Current deduplication technology focuses on block
level redundancy of data because it provides high
redundancy with a manageable deduplication
process.

Why Deduplicate Data?
  • Backup and Archive copies by nature have lots of
    redundant contents common block patterns inside
    DBs, images, file versions, etc.
  • Eliminate redundant block patterns across file,
    databases, images and your archive retain more
    backup copies on disk
  • 90 reduction in disk usage
  • Data cant spin for everextend and preserve that
    reduction benefit to offline storage to support
    retention, vaulting or offsite DR needs
  • 90 reduction in tape usage

Why Deduplicate Data?
  • Data is growing at an alarming rate. Faster
    than hardware capacity is growing
  • Less Disk and Tape to consume and manage
  • Less power and cooling in the data center
  • Preserve current infrastructure (space and
    hardware)
  • Less people required to manage more data

Types of Dedupe Solutions
All Deduplication works using the same
process!!!! The only difference is where the
steps occur.

Types of Dedupe Solutions
Appliance Based
Advantages
  • All processing occurs within the system.
  • The dedupe database and storage are contained
    within the unit
  • Data is deduplicated either in-line or lands in a
    common storage area and is then deduped
    post-write.
  • Easy to acquire
  • Dedicated Hardware and to the processing
  • Flexible deployment options

Disadvantages
  • Do not scale easily
  • Limited scope of de-duplication
  • Requires more data to flow through backup and
    archive process
  • Ties you into a specific solution
  • Can become a performance bottleneck

Types of Dedupe Solutions
Software Based
Advantages
  • Lower cost of acquisition
  • More efficient in limiting data flow
  • Easier to manage
  • Balances performance and processing over entire
    process
  • Free to choose whatever hardware makes sense

Disadvantages
  • More complex to license
  • Tied to a specific software package
  • Requires hardware for performance that is not
    all-in-one

Types of Dedupe Solutions
Client Side Dedupe
Advantages
  • Most efficient in limiting data flow
  • Best overall performance in backup environments
  • Free to choose whatever hardware makes sense
  • Easier to manage than Appliance

Disadvantages
  • More complex to license
  • Tied to a specific software package
  • Requires hardware for performance that is not
    all-in-one
  • Heavier processing requirements on clients
