Archiving Software Buying Guide

Some data archives are little more than "dumb" disk arrays, but the more sophisticated archives provide data deduplication for single instance storage, robust power conservation features, and immutability for data that may be needed as evidence in litigation. What criteria must a storage administrator consider to evaluate products associated with data archiving initiatives?

  • CAS platforms

    Content-addressed storage (CAS) is a specialized type of archive that provides the inexpensive and high-capacity storage needed to retain data that, although accessed infrequently, still has long-term relevance to the enterprise. More importantly, CAS provides immutability to data stored in fixed locations on disk (the content address). CAS has become indispensable for organizations concerned with litigation and compliance, and this chapter will list the criteria for purchasing CAS systems.

  • Index and search software

    Even though archived data may have been unused for years, it must be located quickly when needed to address critical business issues like discovery requests or regulatory compliance audits. Consequently, index and search products have emerged as essential enterprise tools. Indexing creates catalogs of file content based on the metadata applied to content as it is stored. Search combs through indexes, comparing criteria against metadata and presents results to the user.

  • Policy manager software

    Storage has no intrinsic knowledge of what it's storing -- a storage system does not understand the relative importance of data to the enterprise. Policy manager software (policy managers) provides the guidelines that dictate which data to store, where to store it, when to move it and, finally, when to dispose of the data once it's aged.

  • Selecting an archiving product

    Data archives have become a core element of the storage infrastructure. Archives today have two purposes: They hold a vast spectrum of data that does not require frequent access, and they ensure that more relevant data is retained (and then deleted) to meet regulatory compliance needs.
