                    Evan Marcus (Archivas)
                    Enterprise Archiving

 Due largely to new governmental regulations such as Sarbanes-Oxley
 and HIPAA, organizations are expected to maintain and protect
 critical fixed-content data, such as medical records, corporate
 financial data, recordings of customer support phone calls, and
 email for long periods of time, often 20 or 30 years or more.
 Traditionally, the method for preserving data for such long periods
 of time has either been to store the data online on large NAS or
 RAID disk arrays or on magnetic tapes or optical disks, which can
 then be stored offsite. 

 Traditionally, storing the data online is very expensive; even at
 today's prices, it can cost over $100/gb to store data on NAS or
 RAID arrays. Tapes and optical disks are less expensive, but are
 prone to being lost, stolen, or damaged (as has happened recently in
 several widely publicized cases). It is also very difficult to
 search off-line (and off-site) media for specific data when lawyers
 demand all email about a particular customer from five years ago,
 and give you 72 hours to deliver it.

 And neither of these solutions are designed for long-term storage,
 protection, and rapid retrieval of data.

 A third method of storing fixed-content data is in a CAS or Content
 Addressable Storage system, where data is stored in an encrypted
 form, based on a hash key. Data can only be retrieved with the
 original application, and there is no way to search the data.

 A newer solution has emerged that is far less expensive than storing
 the data on expensive NAS or RAID arrays, and that will still keep
 data online so that it never leaves the network, and can be easily
 searched and retrieved quickly, since it can be stored in native

 The solution is an archive cluster, built from a collection of
 inexpensive commodity systems and SATA disks. The hardware is
 arranged into a cluster so that the failure of any disk or system
 (pretty much inevitable when inexpensive hardware is used), or of
 two or three components at the same time, does not affect the safety
 and availability of the data. Data is stored online, is accessible
 through standard interfaces, and is totally searchable. Costs can
 be as low as $12-$15 per GB, depending on the size of the archive,
 and clusters can scale to dozens of petabytes or more.
