Database server archiving and restoration overview

Archiving and restoring the server is the most complex—and the most difficult—way to back up and restore databases. Therefore, avoid using the server archive and restore commands unless you are familiar with database logging techniques and neither of the methods discussed previously is practicable in your environment. Because the administrative complexities of this backup method are considerable, it might be more cost effective for you to invest in hardware solutions for high availability, such as disk mirrors or other RAID capabilities, and to use one of the other backup methods to protect against complete system failure and satisfy other backup requirements.

A server archive creates an archive (servername) file containing only the metadata for the server databases, instead of producing a pack file that contains the file system data and the metadata or a dump file that contains metadata for a single database.

The only significant advantage to server archive is that it enables incremental or even continuous online backup of the metadata.
