Exporting and Importing the Server Metadata¶
You can export the metadata of the Server for backup purposes or to re-create the same metadata in another Virtual DataPort server. You can also export the metadata of one Virtual DataPort database or even just a single element.
By default, Virtual DataPort encrypts sensitive data within the export file using a fixed export key, so every installation is able to import the metadata. This makes it easier to transfer the settings from one server to another but it can be considered a security risk. You can change this export key with the configure_vdp_export_key script. This way, only those servers that have configured the same export key will be able to import the metadata.
If you are going to use the Solution Manager to migrate changes in the server’s metadata from one environment to another (Promotions), use the same export key in all the environments.
The export process can store the metadata in:
A single file, which will contain the VQL statements to recreate the metadata.
Two files: one that contains the VQL statements to recreate the metadata and another one that contains the value of the parameters that depend on the environment where the Server is running.
Or, to a Repository of files where the VQL statements that create each element are stored in a different file. Only use this option if you want to store the metadata on a version control system that is not supported by Virtual DataPort. To store the metadata in one of a supported VCS, use the VCS integration of the administration tool (see section Version Control Systems Integration)
The following sections explain how to:
