Backup is like a strategy to
keep your valuable data in the safe zone. Like other data assets, email
depository is a backbone for any individual or corporate. If we talk about MS
Outlook, it holds centralize data file i.e. PST. In a PST file, users can
access all components like emails, contacts, calendars, journals etc. But, it
should be intact to avoid any kind of access barrier.
Being a responsible user,
you should make sure that availability of recently updated data which includes all
items (Emails, Contacts, Calendars etc.).
In some cases, Backup in
Outlook helps an organization to recover from disaster like pain. For Example: If
your personal storage table (PST) file gets error or bug. Then, probability of
corruption in MS Outlook is high. In this case, backup is a single assistance
to re-gain the lost emails again. So, it is a useful practice for 100% data
safety assurance at user’s end.
