      The Sun JDK zip API fails when trying to open zip files larger than 2 GB. It has been suggested that we should investigate alternative APIs.

      14:31:58,158 ERROR [ExportUtils] Error determining export type from export zip: /data/confluence/restore/david.zip
      java.util.zip.ZipException: invalid END header (bad central directory size)
      at java.util.zip.ZipFile.open(Native Method)
      at java.util.zip.ZipFile.<init>(ZipFile.java:203)
      at java.util.zip.ZipFile.<init>(ZipFile.java:234)

      In the meantime, the suggested workaround for this issue is to disable automatic backups and backup the Confluence database and home directory using an external scheduling system.
