Yes, in some cases you will need to backup the OST file. Here are a few reasons because of which you need to back up the OST File in Outlook 2010, 2013, 2016, 2019.

There can be numerous situations that result in creating an archive file of OST (Offline Storage Table) in Outlook.

  • OST Synchronization Problem: You can work with OST files in offline mode. But when Outlook is synchronized with the Exchange Server, it becomes difficult to work on the OST file. For this reason, it is needed to back up the OST file.
  • Authentication Issue: To avoid all the complex procedures to access data from the Exchange Server, it is better to keep an archive of the OST file.
  • Outlook Data Recovery: You can lose Outlook data because of various reasons like accidental file deletion, file corruption, highly damaged OST files, data cannot be accessed errors, etc. So to avoid loss of data permanently, it is recommended to keep a contingency plan and backup .ost files for the accounts.
  • OST Data File Corruption: OST files can get damaged because of virus attacks, abrupt shutdown, and other software-related issues. As a result, the OST file becomes inaccessible. Hence, it is necessary to Backup the Offline OST files of Outlook 2019, 2016, 2013, 2010 & Exchange OST files.

Final Thought:

Although the above-mentioned manual methods can help you to backup OST files, they have their own disadvantages like converting them into a PST file and not being able to archive a complete Outlook data file.

Moreover, the manual process is complex, and when you are dealing with a large amount of precious work-related data you cannot afford to take chances. Hence, it is recommended to make use of a completely automated and safe method to backup and migrate using the Remo Outlook Backup and Migrate tool.
