Muskan soni.
To-
Mr. Devarshi Mehta sir.

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

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

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

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

26. Backup Technology options
• Backup to Tape
 Physical Tape library
• Backup to tape

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

28. Backup to Tape

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

32. Backing up files and folders
(file backup)

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.
