Websites and Web Hosting Service Providers

• A website refers to a group of related web pages
  and content (data) that is browsed online. It is
  located under a single domain and is identifiable
  by a common domain name.
• Every website that is visited over the Internet
  is made accessible by a certain web hosting
  service provider, which is also referred to as a
  web host. Server space is leased by this web host
  to store as well as make available the files of a
  website. These web hosts also provide the
  necessary services and the technologies that
  deliver those files to make the website
  accessible for online viewing.
• Terms such as Cloud Hosting Company in India or
  the Best Windows Hosting Company as well as the
  Best Web Hosting Company in India are used to
  refer to companies that provide various types of
  web hosting services.

Data Loss

• Data loss, which is also called data leakage,
  refers to the condition where a users data gets
  corrupted, deleted and/or made unreadable due to
  certain reasons. As is evident from the term,
  there is a loss of data that is caused by the
  deliberate or indelible rate acts of a user
  and/or through any software or application. It is
  known to have taken place when one or more data
  components can no longer be utilized by a user or
  by a requesting application. It can happen to the
  data that is stored as well as to the data that
  is being transmitted over the Internet.

Causes of Data Loss

• Data corruption intentionally or unintentionally
• Human error
• Hard drive damage
• Hard drive formatting
• Software corruption
• Data getting intentionally or accidentally
  deleted or overwritten by a user
• Virus or malware infection
• Hacking
• Partition loss
• Power outages
• Data storage device getting physically damaged or
  stolen
• Data theft over the network by any network
  intervention attack Encrypting login pages (For
  example, using SSL encryption)

6
Consequences of Data Loss

• Theft/loss of confidential information
• Hampering of productivity
• Loss of reputation as well as loss of customers
  trust towards the business
• Economic loss
• Legal trouble
• Business failure (in extreme cases)

Data Recovery

• Data recovery refers to the process of
  restoring data that has been lost, gotten
  corrupted, accidentally or unintentionally
  deleted, and/or made inaccessible to the user for
  some reason. Data recovery can be achieved by
  various means. Data recovery helps to get the
  users database back to a previous state that it
  was in, prior to the data loss. The process of
  data recovery helps to regain the most recently
  saved state of data, before the loss. Data
  recovery does not apply to any information that
  has never been written to a storage, such as a
  document that got created but was not saved prior
  to the data loss. It the context of data recovery
  it is important to mention that any information
  that has been overwritten cannot be recovered.
  This makes it critical to ensure that nothing
  gets written to the storage till the time the
  last file gets recovered.

Phases of Data Recovery

• In general data recoverys process entails
  four phases but it might vary with regard to the
  type of data loss and the recovery process that
  is required.
• 1st Phase- Repairment of the hard disk drive
• 2nd Phase- Image the drive to a new drive or a
  disk image file
• 3rd Phase- Files, partitions, MBRs and file
  system structures logical recovery
• 4th Phase- Repairment of the retrieved damaged
  files

10
Backup and Recovery

• Data backup refers to the process of copying or
  archiving files and folders, in order to ensure
  restoration of data for the purpose of being able
  to regain it in case of data loss. This acts as a
  protective measure, which helps to maintain a
  copy of the users data that can be easily
  restored in the event of any untoward incident
  resulting in data loss. It should be ensured that
  data backup happens automatically and at regular
  intervals. If not, then the risks associated with
  data loss and the failure to recover the lost
  data increase significantly.

11
Considerations for Data Recovery

• In the context of data recovery certain important
  factors need to be considered which are mentioned
  below, in no particular order-
• Choosing thefiles and folders (data) for backup
• Choosing the compression method to use
• Choosing the frequency of backups
• Choosing the types of backups to run
• Choosing the kind of media for storage of backups
• Choosing the store facility for the backup data,
  to keep it safe

12
Forms of Data Recovery

• The various forms of data recovery are mentioned
  below, in no particular order-
• Digital recovery
• Raid recovery
• Tape recovery
• Hard drive recovery
• Optical recovery
• Removable recovery

Conclusion
We live in a world that is driven by technology.
Data, whether it is personal or business related,
assumes significant importance and its loss can
have serious ramifications, as has been touched
upon in the previous slides where the
consequences of data loss have been mentioned.
Hence, it becomes vital to keep any data safe by
maintaining its backup at regular intervals. This
ensures that in the unfortunate and unwelcome
situation of loss of users data, it can be
restored without any difficulty.
