Agenda Doporučené způsoby zálohování a retence dat - zhodnocení jednotlivých technologií a rady pro jejich použití v modelových situacích IBM portfolio produktů pro oblast zálohování a archivace - Páskové systémy (Tape Systems) - Virtualizace pásek (IBM Protectier VTL and deduplication) - IBM Information Archive


Nazadržitelný růst dat Více než 50% firem aktivně spravuje mezi 1TB až 99TB dat, důvody:

1)

Business požadavky – držení detailních informací o produktech, zákaznících, službách pro tvorbu strategie, obch. růstu a zvyšování úrovně služeb (business aplikace, data warehousing)

2)

Uživatelská (nestrukturovaná) data – foto, video, audio

3)

Interní a externí pravidla, která nutí firmy držet data delší dobu


Příčiny ztráty dat minimalizovat nárůst investic do storage (omezený budget) Zajistit ochranu dat v souladu s požadavky a ochranu dat před jejich ztrátou


Infrastruktura pro zálohování a obnovu – páska nebo disk ?


Osvědčené postupy při zálohování a archivaci dat 1) Zálohujte efektivně Data Lifecycle management Uvážit hodnotu dat a jak se jejich hodnota měmí v čase - volba média (vysokorychlostní disky nebo páska) - proč mají data „letět první třídou, když by stačil vlak“


Osvědčené postupy při zálohování a archivaci dat 2) Tiered Storage Architecture Určení storage tier pro jednotlivé typy dat: RTO (Recovery Time Objective) – jak rychle potřebujete mít data obnovena

RPO (Recovery Point Objective) – jak aktuální musí být data, aby byl dopad na váš business minimální

Budget – omezení volby technologie množstvím finančních prostředků

Osvědčené postupy při zálohování a archivaci dat 2) Tiered Storage Architecture Archivace Neměnná data, možný přesun na nižší storage tier (např.) Volba technologie dle RTO, náklady na nižší storage tier, škálovatelnost, floor space, životnost médií, bezpečnost Data Retention Data pro dlouhodobou archivaci za účelem shody s externími pravidly (zákony, vyhlášky) a za účelem interního kontrolingu Zálohování a obnova RTO, RPO, bezpečnost dat Business Continuity a Disaster Recovery RTO, RPO Správný technologický mix pro vzdálenou lokalitu může značně ušetřit celkové náklady © 2010 IBM Corporation

Osvědčené postupy při zálohování a archivaci dat 3) Nepodrobujte svá data riziku Více úrovní ochrany dat

3 kopie dat v různých lokalitách včetně vzdálené lokality pro případ katastrofy Různé formy médií (mix disky a pásky) – předcházení selhání systému. Alespoň jedna kopie offline (izolace) Předchází replikaci poškozených (napadených) dat Data encryption Dnes dobře dostupné jako samostaný SW nebo součást HW Technology mix


Osvědčené postupy při zálohování a archivaci dat 4) TCO Kromě nákladů na pořízení technologie, dále: Elektrická energie Floor space Management Škálovatelnost


Osvědčené postupy při zálohování a archivaci dat 5) Ověrení možnosti obnovy dat Pravidelné ověřování Životnost technologie Efektivní obnova


Vybalancovaná volba technologie

Customizable Protection Levels Most Flexible and Most Comprehensive Data Retention Policies

Basic Protection enables the greatest flexibility for managing an organization’s information retention needs Intermediate Protection allows IT administrators to increase and decrease retention periods as needed, but information deletion is only allowed after the retention period has expired

Basic

Intermediate

Maximum

Maximum Protection helps IT administrators manage information with strict business, legal or regulatory retention needs


Advanced Data Protection Features

Multiple Protection Levels

Basic to maximum protection levels address all possible data retention requirements

Enhanced Disaster Recovery

Advance Copy Services increase the availability of archived documents and prevents data loss in the event of a disaster

Redundancy

Clustered nodes & Redundant Array of Independent Disks (RAID) 6 to maintain data integrity even in the event of two disk failures.


Advanced Data Protection Features

Encryption

Enhanced Tamper Protection

Shredding

Encryption can provide added security for data storage and remote data transmission

Patent-pending feature eliminates root access

The destruction of deleted data to make it difficult to discover or reconstruct that data later.


Data Optimization Features

Deduplication

Single instance storage of data

Compression

Compression can, on average, reduce the data’s size by 60 - 90%

Hierarchical Storage Management

Automatically distributes and manages information on disk, tape, or both
