What is the need to backup PST files in Outlook?

MS Outlook is one of the most popular and widely used Email clients. The Outlook versions that are commonly used are Outlook 2010, Outlook 2007, Outlook 2003, and Outlook 2002. Outlook 2000 is not used now-a-days.

PST File corruption:
MS outlook stores all mail data such as: Emails, Attachments, Contacts, calendar entries, Notes, journals etc. in PST file format. The PST files in Outlook have a predefined maximum file size limit.

The Default PST file size limit varies from version to version.
  • Outlook 2010: 50 GB
  • Outlook 2007 and Outlook 2003: 20 GB
  • Outlook 2002 and previous versions: 2 GB
The increasing PST file size can hamper proper Outlook functioning and it can also slow down your system. It can lead to severe PST file corruption and other related Outlook errors.
Besides the PST file size limit there are several other reasons that lead to PST file corruption.

Common reasons for PST file corruption:
  • Unexpected or improper shutting down of Outlook
  • Improper/interrupted compaction of PST
  • Virus/malware infection
  • Contradiction with newly installed hardware/software
  • File system corruption
  • Operating system’s malfunction etc.
Whenever, you try to access data from a corrupt PST file, you will be followed by some error messages that indicate the PST file corruption. Any kind of corruption in PST file makes the data stored within it inaccessible and unusable. So, to avoid such data loss situations its better to backup the PST files on regular basis. In case your PST file gets corrupt then, you can easily restore the mail data from the backup copy of PST file.
