Due to limitations of the original ZIP file format, and the TrueZIP library used to generate ZIP files, it is not possible to export a Bamboo instance when the resulting ZIP file, or the original size of any of its components, is larger than 4GB. Instead, you will need to backup Bamboo manually. We strongly recommend performing regular backups.
To backup Bamboo manually:
<bamboo-home>/xml-data/build-dir
beforehand to reduce the size. Zip this backup.To restore your Bamboo instance to a previous state:
../Bamboo-Install-Directory/webapps/WEB-INF/bamboo.init.properties
file to point to your backed-up Bamboo-Home directory.
