Archiving refers to making a copy of the data for later reference, while backup is intended to restore the data, and the original data is often deleted. It is stated that the primary purpose of the archive is to make it easier to search a collection of data, such as contracts, customer signatures, and demolished building designs.

There is more data to archive. For example, if an employee who thought he had permission to work at night was dismissed when he actually went to work at night, a company lawsuit against the company said that the word “ night work '' or “ after regular hours '' or a company that worked at night You may be required to submit electronic data, such as an email exchange containing your name. In such a case, if you leave an archive, you can easily prepare data.


When retrieving the original data, backup and archive are also called differently; backup is called restore, and archive is called retrieve. When restoring, the target data is often a single file, server, or database, but retrieving often involves a set of related data. A restore will recreate a point in time, while a retrieve will have a range of data, such as emails from the last three years.

Curtis Preston says that many people are struggling to keep their previous backups like archives or to retrieve the data they had stored as backups. If the electronic data requested to be submitted in the lawsuit cannot be retrieved and the submission is delayed, there is a possibility that concealment of evidence may be suspected and an adverse presumption may be made.Morgan StanleyHe said that he had lost billions of dollars in lawsuits for that reason.
