TUT 134 Backup and Recovery: A Linux perspective
By Amin Y Marts – Applied technology strategist amarts@novell.com
- Generic Backup Environment
- One backup server with attached tape device
- Backup targets of NW, Suse, and Windows targets with direct attached storage
- Internet SCSI Defined
- iScsi is an end to end protocol for transporting storage I/O block data over an IP network
- Common key advantages
- Builds on stable and familiar standards
- high degree of interoperability
- scales to gigabit speeds
- price per port
- Suse Linux Enterprise advantages
- Graphical iSCSI management tools
- Support of iSCSI as both initiator and target
- ISCSI Deployent
- Host Bus Adapters
- 85% of the market uses software initiators
- 10GB iSCSI requires host bus adapter
- Encryption
- Segregation of storage and network traffic
- vLan
- Physical segregation
- Misc
- Expect 10% overhead on typical server hardware
- iSCSI vs. Fibre Channel
- Fibre Channel
- LUN Masking
- Zoning
- Host Identification via World Wide Web Name
- iSCSI
- Physical and virtual network separation
- IP address access restrictions
- CHAP authentication
- Tape Drive Technology: Terms
- Tape Drives
- Linear
- Helical
- Azimuth
- Trajectory of an angle measured in degress goign clockwise from a base point
- Servomechanism
- mechanism designed to manipulate Read/Write Heads into the appropriate positions
- Goal of all of these technologies is to make sure a steady stream of data is available at the tape head.
- Archive and Backup – What’s the Difference
- Backup
- Collection of non-contiguous data sored for the tactical purpose of supporting the physical infrastructure
- Archive
- Collection of searchable stored data whose restoration aligned with strategic business goals or stressors
- Think the new shadow volumes with OES2
- Benefits
- Regulatory Compliance
- Storage Management and costs
- Backup Application Performance
- Protection against
- Litigation (data capture and production)
- Government Audits
- Open Records Request
- Knowledge Management (data mining)
- Features
- Robust indexing capability
- Robust storage medium compatibility
- Secure archived-data
- Access Logs
- Minimal End-user manipulation and training
- Non-IT access and management
- Configurable to corporate retention policies
- Novell Storage Services
- Access control with Granular Rights (vs. rwx)
- File salvage from the client
- Data Shredding
- Novell Backup Environment Devined
- Backup Target
- SMS (Storage Management Services)
- SMDR (Storage Management Data Requester)
- TSA (Target Service Agent)
- API’s
- 3rd Party Backup application
- Partner Issues
- Why are some backup software vendors better suited to Suse LInux and OES
- Many don’t backup NSS metadata
- Q and A
- Zmanda for sles backup (not OES)
- Open Source
- OES compliant
- Syncsort
- Symantec
- CA
- Commvault
Overall I was dissapointed with the quality of this presentation. I was hoping for a discussion of unique issues surrounding Linux backup vs. NW Including volume types, boot volumes, and NSS and iFolder issues. None of this was covered.
