BLOBs and POSKeyErrors¶ The Plone CMS from version 4.x onwards stores files and images uploaded to the ZODB as blob. They exist in a var/blobstorage folder structure on the file system, files being named after (opaque) persistent object ids. When using the default backend, the objects themselves, without file payload, are stored in an append-only database file called filestorage and usually the name of this file is Data.fs. If you copy the Plone site database object data (Data.fs) and forget to copy the blobstorage folder(s), or if data gets out of the sync during the copy, various problems appear on the Plone site: You cannot access a content item for which the a corresponding blob file is missing from the file system; you cannot rebuild the portal
