Abstract

Archive We’ll establish a standard definition of data archiving, forces driving it’s adoption in enterprise environments and the benefits to be achieved with an optimized approach. We’ll also review data lifecycle divisions and subcategories to understand where data should be stored (including storage tiers) and why (how to value data). By examining guidelines and policies for an effective archiving system we’ll review how companies can optimize their storage network and reduce the bandwidth requirements needed for replication and disaster recovery – necessary elements to satisfy data integrity and regulatory compliance requirements. In addition, we’ll review how today’s active archive solutions enable affordable, online, long-term data retention through case studies from the healthcare, broadcast, finance, education and oil/gas industries. Learning about the software applications available to manage data archives will help companies facilitate user online search and access


What archive is

SNIA – A collection of data objects, perhaps with associated metadata, in a storage system whose primary purpose is the long-term preservation and retention of that data.Archives are long term repositories for the storage of records. Electronic archives preserve the content, prevent or track alterations and control access to electronic records. (Source: Sedona Principles)Specialized repository (including the supporting processes, policies, hardware, and software) used to preserve information and data for the long term. (Source: Building a Terminology Bridge for Digital Information Retention and Preservation Practices)

What archive is not…

NOT backupNOT data protectionNOT user selected, but policy drivenNOT “keep everything forever” – deletion policies are criticalNOT storage tiering

Moving older data to lower cost tiers for storage reclamationStorage that is physically partitioned into multiple distinct classes based on price, performance or other attributes. Data may be dynamically moved among classes in a tiered storage implementation based on access activity or other considerations. Source: SNIA

Archive vs. Backup

ArchivePrimary record of dataRetention and access Long-termData maintained for analysis, value generation, history, or complianceOnline or nearlineNot data protection

BackupSecondary copy of dataRecoveryShort-termData typically overwritten periodicallyNot archive

Archive vs. Tiered Storage

ArchiveRetention for future reference or compliancePolicies determined by regulations

Dynamic Tiered StoragePrimary storage reclamationPolicies driven by access patterns

Challenges – Tiered Storage

Primary storage overflowing with aged data95% of data growth is unstructured data which is rarely accessed after creation*Issues with existing data management policies sometimes compound the data growth problemBackups taking too long; backing up static dataReluctance to address the issue due to lack of understanding the value of the dataLack of visibility into access patterns

Challenges – Archiving

Regulatory requirements:RetentionDisposalChange history

Important information at risk of being lostReferencePerceived as difficult to implementNo one cares – sometimes even inside IT

10


Why archive?

Determine retention requirements on creation. If archive, then why archive?

Because you want toBecause you have to

Retention Requirements

Source: 100 Year Archive Requirements Survey


Archive – Because you want to

Data has some value to the businessRequires policies and software to enable migration from the production environment into the archive environment

13


Archive – because you have to

Data retention is required for legal reasonsLegalComplianceRegulatory

Archive policies typically require legal approval

14


“Some” Legal Requirements

FRCP – Federal Rules of Civil ProcedureRule 16 – Pretrial ConferencesRule 26 – General ProvisionsRule 33 – Interrogatories Rule 34 – Production of informationRule 37 – Failure make disclosure or cooperate

SEC 17 – specifies retention, authenticity discovery, security, DR with penalties for noncomplianceHIPAA – requires security, privacy, authenticity, retention with penalties for noncomplianceSOX – penalties for knowingly altering, concealing, or destroying informaiton relative to an investigationGramm-Leach-Bliley Act – protect PII confidentiality and authenticity with penalties for noncomplianceCFR – requires preservation, authenticity, retention, protection, availability 15

Recommendations

Archiving is not an isolated / stand-alone solution. Archiving should be part of a broader data management view. Do not implement an archive solution and simply move your data management problem from one place to another (ex. “archive everything forever”)Establish retention periods and disposition polices for all business important information at creationClassify information upon creation and save a copy of all required records in a proper preservation-class archive upon creation

Archive Benefits

Meet compliance requirementsPreserves business important informationSimplified data managementSimplified backup/recovery operationsSimplified disaster recovery operations

Active Archive Approach

Extended File System


Active Archive Result:


Active archiveA set of unstructured data such as office files and documents, video/audio files, email PST files and CAD/CAM files, that contains production data, no matter how old or infrequently accessed, that can accessed online.

Fueled initially by introduction of high density, lower power disk drivesMomentum continued to build with release of power efficient disk arrays and high density, lower power disk drives.Next generation archives can leverage the latest in automated tape technologies offering high density, low power, cost effective archive storage

Ineffective Storage Management


Requirements for Active Storage

26


Tape technologies are reliable…

Reliability has increased 700% over the technology available a decade earlier

• Advances in the coating of tape film

• Read-after-write data verification

• Error correction codes

• Drive technology features simplified tape paths and servo tracking systems

Beech, Debbie. “Best Practices for backup and long-term data retention” SylvaticaWhitepaper. The evolving role of disk and tape in the data center. June 2009

27


Some libraries today have the intelligence to proactively alert if a media, drive or hardware issues are developing

Gone are the days of not knowing if…A tape has been used beyond any manufacturer thresholdsThere has been environmental damage to mediaFailures are drive or media relatedData is on the tape media

28

…and even more reliable in intelligent libraries


Tape storage offers high energy efficiency

29

Tape Library Disk System

Clipper Group Study, “Tape and Disk Costs”- Starting with 125 TB of data - Assuming 14.5 cents per kW/Hr increasing by 10% per year


Tape libraries offer the greatest storage density

Reclaim space: 44 – 218%Low density disk array

Same capacity, smaller

footprint30


Tape Libraries are Fast…

31

* Based on benchmarked data; assumes 2:1 data compression* Based on 120 LTO-5 Drives* *Times vary based on library and tape drive in use

…really fast!

Write to tape: 121 TB/hr*

Access from tape: 65-75 seconds avg**
