Data Backup

• Data backup is a proactive approach that
  maintains the safety of data and is the easiest
  and the most effective way to avoid loss of data.
  Data backup involves maintaining and storing at
  least one additional copy of the most updated
  version of ones data to ensure its availability
  at all times. Data or work that isnt easy to
  replace and is important for ones business,
  should be backed up. Such data can include
  databases (for financial data), spreadsheets,
  customers data, word processing documents, etc.
• Backups are meant for recovering deleted or
  corrupted data as well as for recovering copies
  of older files. Hence, backups are tools for
  disaster recovery. To ensure the effectiveness of
  data backup, this process should be automated and
  should be carried out regularly. Moreover, the
  copies should be saved on different mediums.
• To digress, the data of websites are stored on
  the servers of web hosting companies and
  delivered from there, over the Internet, to make
  websites accessible. Most of the professional web
  hosting service providers provide data backup
  facility to ensure the safety of their clients
  websites data. The most efficient web hosting
  companies are usually referred to as the Best
  Website Hosting Company, the Best Cloud Hosting
  Company, the Best Windows Hosting Company etc.

Data Backup Plan

• There needs to be an efficient data backup plan
  for the success of any data backup process. Any
  effective data backup plan will take into account
  the following-
• The types of data that need to have a backup
• The compression methods that should be used
• The frequency and the types of backups
• The type of medium for storing backups
• The storage facility involved in storing the data
  safely

Data Backup Strategy

• A data backup strategy must include the
  following-
• Onsite Backups- Such backups are faster to
  restore.
• Offsite Backups- This type of backup maintains
  copies of backups offsite. Such a backup can be
  accessed either manually or through the cloud.
• Optimized Backup Schedule- Any effective data
  backup process should be regular and should be
  carried out as per an organized schedule.
• Backup Testing- Backups need to be tested
  regularly. IT staff should be adequately trained
  to access and restore data backups quickly.
• Organized Storage System- The storage repository
  for backups should be organized.
• As per the 3-2-1 backup strategy, at least 3
  copies should be maintained of data. 2 different
  types of storages should be used for data backup.
  Additionally, at least 1 copy of the data must be
  maintained offsite.

  proud?

Full Backup

• In full backup every file in a system which is
  important for the business is copied. It is not
  only the first copy of the data but also is the
  most reliable copy. It is usually time consuming
  and requires comparatively more space than other
  types of backups. Its advantage is that it
  renders the process of restoring data extremely
  fast.

9
Incremental Backup

• In this type of backup, the initial backup is a
  full one. The successive backups store the
  changes that were initiated after the previous
  backup. The process of restoring lost data is
  longer in it but the backup happens more swiftly.

10
Differential Backup

• It is similar to an incremental backup as in it
  too the initial backup is full and the successive
  ones only store the changes that have been made
  since the last backup. More storage space is
  needed in it than in an incremental backup. The
  restoration happens more speedily in it.
