Description

NOTE: This suggestion is for Confluence Server. Using Confluence Cloud? See the corresponding suggestion.

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.
