Poor policy management

No Standards or procedures

No indexing or search capabilities

Poor segmentation

Data is “clumped” on media haphazardly according to source time and place rather than according to policy

Data sharing the same media cannot be truly expired

Retrieval requests will bring back unrelated data

Unworkable as everything we need archives for…

Legal discovery process

Long-term retention

Distant-future recoverability

Consistency of data

Archiving Approaches

Traditional archiving

Point-in-time copy of set of related data

E.g., quarterly financials

Sometimes original data deleted after archive

The backup-archiving connection

Hierarchical Storage Management (HSM), NAS, SANs

Automated migration of data to lower cost storage or tape

Typically based on access-based file aging

Data migrated and a “stub” left in its place

File recalled to primary storage upon re-access

Active archiving (redirection)

Pointers to archived data

Supports single instance store

Data recalled without re-copy to primary store

Indexing and quick retrieval

Key Backup Considerations

Frequency – when, how often is an archiving copy to be taken

Retention – how long should the data be kept

Retrievability – drives access/search architecture

Taxonomy – indexing requirements for retrieval

Ingestion – what will be captured and when

Security – both physical (site) and logical (encryption)

Authentication – roles and responsibilities, access control

Immutability – requirement to demonstrate data is unchanged

Render options –is it to be transformed into information

Future proofing – common formats, pdf, xml

Refresh criteria – expiration of media life, platform life

Purge – when is archived data no longer required and how will it be destroyed
