It is recommended to make periodical backup copy of the database especially prior and after intensive modifications in the system. Option “Backup” creates backup file which is possible to download directly from web browser. After downloading, this backup file is automatically deleted from the system. As an option, backup file can be compressed in zip format.

Optimization is not necessary but is recommended to be done periodically, especially in the case when significant amount of data is deleted from the database (system). As a result, system database will be defragmented; it will occupy less disk space and would have faster response to queries.
Option “Update” is used only if new version of CMS is released.

“Clear cache” option deletes obsolete and cached files from the system. All thumbnail files are deleted in this operation, but necessary ones would be automatically created when required by system. Cached web pages are also deleted. This procedure also saves some storage space.
