Data retention is defined as preserving the existence and integrity of data for some period of time or until certain events have transpired, or the combination of the two.
Compliance covers a broad area where the storage of data is in accordance with a standard, specification, or clearly defined requirement. Due to these compliance requirements IT departments are also under pressure to retain electonically stored information (ESI) like email, IM, blogs in case they are required for litigation purposes.
Data archives are built to optimize data retention by storing information (and associated metadata) on platforms using policies that facilitate long-term retention, search and retrieval. Electronic archives preserve content, prevent or track alterations and control access to records.
Archiving is thus most effectively implemented at the LAN layer, where multiple storage systems can be leveraged. Data archives can utilize disk or tape storage systems and may be created at the start of a data management infrastructure design or added later as a repository to hold data moved from primary storage.
