You can use content exporting for long-term archiving of content, synchronization of data among several vaults, or freeing up disk space on the server.
Do the following steps to export content:
If the Export only changes since latest run option is enabled, only the files and objects that are new or have changed since the given date and time are exported. If you are exporting metadata structure elements while this option is enabled, the elements are not exported unless there have been changes made to files or objects.
