The Network File System (NFS) is the most widely used network-based file system. NFS’s initial simple design and Sun Microsystems’ willingness to publicize the protocol and code samples to the community contributed to making NFS the most successful remote access file system. NFS implementations are available for numerous Unix systems, several Windows-based systems, and others.
Slides present data and information system. In any information system security and integrity is the prime concern. How we can make sure stored data is more secure and generated information should be accurate, reliable and consistent.
Just created a slideshare presentation giving a basic introduction to the Confidentiality, Integrity & Availability (CIA) Security Model. You can see more slideshows on http://www.slideshare.net/ImranahmedIT or visit my website: http://imran-ahmed.co.uk

• We sleeping well. And our mobile ringing and ringing. Message: DISASTER! In this session (on slides) we are NOT talk about potential disaster (such BCM); we talk about: And what NOW? New version old my old well-known session updated for whole changes which happened in DBA World in last two-three years.
• So, from the ground to the Sky and further - everything for surviving disaster. Which tasks should have been finished BEFORE. Is virtual or physical SQL matter? We talk about systems, databases, peoples, encryption, passwords, certificates and users.
• In this session (on few demos) I'll show which part of our SQL Server Environment are critical and how to be prepared to disaster. In some documents I'll show You how to be BEST prepared.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Outline
• What is backup
• Backup strategy
• Recovery procedures
• Factors in recovery procedures
• Backup purposes
• Types of backup
• Backup architecture and process
• Backup topologies
• Backup technology options
• Features
• Installation of Acronis
3. What is a Backup?
• Backup is an additional copy of data that
can be used for restore and recovery
purposes
• This Backup copy can be created by:
– Simply coping data (there can be one or more
copies)
– Mirroring data (the copy is always updated
with whatever is written to the primary
4. Backup Strategy
A backup is put in place to avoid
permanent data loss to ensure the
integrity of stored data i.e. can get
back to a previous version and build
up the data correctly if current data
found to be in error.
5. Recovery Procedures
• A backup strategy needs a well
documented and tested recovery
procedure to ensure backup data is
restored properly
6. Factors in recovery procedure:
• A well documented procedure that allocates
roles and responsibilities to staff.
• Availability of alternative hardware and
accommodation if the originals have been
destroyed.
• Availability of original software such as the
customised operating system and application
programs!
• That up-to-date backup data is readily available
7. Backup purposes
– Disaster Recovery
• Restores production data to an operational state
after disaster
– Operational
• Restore data in the event of data loss or logical
corruptions that may occur during routine
processing
– Archival
• Preserve transaction records, email, and other
business work products for regulatory compliance
8. Types of backups
• Three basic types of backups:
• Full backups
• Differential backups
• Incremental backups
9. Full backups
– full and complete backup of entire system
Full Backup
Su Su Su Su Su
10. Differential backups
– storage of all files that have changed or been
added since last full backup

12. Key Features of Differential
backups
– More files to be backed up, therefore it takes
more time to backup
and uses more storage space
– Much faster restore because only the last full
and the last cumulative
backup must be applied
13. Incremental backups
• only archives data that have been
modified that day
Su Su Su Su SuM T TW F S M T TW F S M T TW F S M T TW F S
15. Key Features of Incremental
backups
– Files that have changed since the last backup
are backed up
– Fewest amount of files to be backed up,
therefore faster backup and less
16. • Backup client
– Sends backup data to backup server or
storage node
• Backup server
– Manages backup operations and maintains
backup catalog
• Storage node
– Responsible for writing data to backup device
Backup Architecture and Process
17. Backup Architecture and Process

Storage Node
Tape Library
19. Backup Operation
• Start the scheduled backup process
• Backup data retrieves backup related information from
backup catalog
• Backup server instructs storage node to local backup
media in backup device
• Backup server instruct backup clients to send its
metadata to the backup server and data to be backup to
storage mode.
• Backup clients send data to storage node
• Storage node sends data to backup device
• Storage node sends media information to backup servers
• Backup server update and records the status
21. Restore Operation
• Backup server scans backup catalog to identify
the data to be restore and the client that will
receive data.
• Backup servers instructs storage node to load
backup media in backup device.
• Data is read and send to backup client.
• Storage node sends restore metadata to backup
server.
• Backup server updates catalog.
22. Backup Topologies
• There are 3 basic backup topologies:
– Direct Attached Based Backup
– LAN Based Backup
– SAN Based Backup
23. Direct Attached Backups

27. Backup to Tape
• Traditional destination for backup
• Low cost option
• Sequential / Linear Access
• Multiple streaming
– Backup streams from multiple clients to a
single backup device
29. Tape Limitations
• Reliability
• Sequential Access
• Cannot be accessed by multiple host
simultaneously
• Control environment for tape storage
• Wear and tear of tape
30. Backup to Disk
• Ease of implementation
• Fast access
• More reliable
• Random access
• Multiple host access
• Enhanced overall back and recovery
performance
31. New Features
• File backup and restore
Simple and automatic protection
Complete PC™ backup and restore
Block-level image
Entire computer
Server backup
Files, folders, disks, common workloads
33. • If you are going to create a full backup,
type the file name in the File Name line,
or use the file name generator (a button
to the right of the line). If you select an
existing archive, it will be overwritten.
