NOTHING PRESERVES LIKE AMBERTo protect your irreplaceable digital assets they must be kept safe and accessible. Permanently storing large collections of media requires actively managed enterprise class storage. External hard drives and NAS disk arrays are simply not up to the task. Online data tape libraries are more expensive than they appear and make it difficult to monitor the integrity of your data. The infrastructure at Crawford Media Services includes one of the most advanced private data centers inthe world. CRAWFORD AMBER is actively managed andpurpose built for media archival services at rates belowmany commodity cloud storage services.
ACCESSIBLE DATA AND DISASTER-PROOF BACKUPSData stored in CRAWFORD AMBER is accessible on spinning disk at all times while disaster recovery copies are stored inan underground salt dome thousands of miles away. But there are bigger threats to data than natural disasters. When storing legacy assets for decades, equipment failure and data decayare not just potential threats to your data, they are certain. CRAWFORD AMBER’s Lattus archive employs erasure code, the most advanced technology available to protect theintegrity and durability of your data.

UNDERSTANDING CRAWFORD AMBER’S ERASURE CODE TECHNOLOGYCreating a permanent archive of digital data is a real challenge. Why? Because the most practical digital storage technologies, like spinning disks and data tape use magnetic media. Guess what? Magnetic media is not archival. All those little bits of magnetic information stored on a hard drive slowly lose their charge, and the mechanism wears out, and becomes obsolete, and the information is even bombarded and corrupted by cosmic rays. The combination of these assaults on your information can be called data decay.
You have to copy your data to fresh media before there is too much data decay. In addition to refreshing the media, every scheme for archiving data has relied upon having duplicate copies of the data. The idea is that if one of your copies is lost or corrupted you can fall back on the others. The problem with all of these strategies is that they are time consuming, expensive, and difficult to manage.
The evolution of data storage led to a breakthrough in digital archives technology known as erasure code. The technology is known as erasure code. When data is written to disk it is first encoded with an algorithm that provides forward error correction. Forward error correction is a technique that as-sumes some of the data will be lost or corrupted and has the ability to mathematically reconstruct the original data from only a partial return of the encoded data. Once the data has been encoded, it is also broken up into smaller units called “slices” and spread across many storage nodes. When the data is read back the slices are re-assembled and decoded. If any (or even several) of the slices are missing, the forward error correction makes it possible to rebuild the data perfectly from the remaining slices. By building the storage out of many small nodes and utilizing extremely clever policies to spread the slices the probability of data loss from data decay or system failure becomes fantastically small.
The advantages of erasure code for an archive are overwhelming. Perfect data integrity, immunity to data decay, a much smaller data footprint than replication, high immunity to system failure, automatic re-balancing of data and media refresh as the archive grows.
QUANTUM LATTUSQUANTUM LATTUSObject storage addresses many of the scalability and reliability problems that are introduced with modern data management. Erasure coding provides a new mechanism to achieve much higher data integrity and durability with far greater efficiency than traditional storage solutions.
Lattus blends the manageability and accessibility of traditional file systems with the scalability and durability of object storage.
