What is a Data Domain Restorer (DDR)?
A (Fileserver or VTL) for backup images & “tape”
archives





tar/cpio/etc. files (including images from Symantec, Legato,
…)
NDMP dump images
Database dumps
Copies of critical files
Network (gig-E) attached
A very efficient compression engine


Avoid writing previously compressed data
Let the DDR do the compression
Optimized for a small number of read/write streams
Optimized for large files (multi-megabyte and up)
Not primary storage!
Not a general purpose fileserver or SAN filesystem!

Capacity Optimization: Review
Overall compression = Global * Local


Global compression: Replace non-unique segments with
references (2:1 to 100:1 or more common)
Local compression: LZ compression of unique segments and
other metadata (2:1 common)
The more redundancy the better


Fulls compress more than incrementals, but
~7:1 compression of incrementals/snapshots common

COS eliminates redundant patterns
Incrementals/snapshots contain only changed blocks
COS eliminates redundancy BETWEEN changed blocks
