Avid Interplay Engine Server
The Avid Interplay Engine Server is the central process where all assets and asset metadata are
managed. The main task of the server is to manage all the information that is in the database and
implement the server-side logic of database operations. The database itself is changed whenever
content in the database has been changed; therefore the Interplay Engine process needs fast
access to the location where the database is installed.
Backups
The database files, as well as the assets, can be backed up while the Interplay Engine is running.
For details, see
“Creating and Restoring Database Backups” on page 29.
