• Non-clustered Fedora, using Infinispan cache backed by LevelDB (config)

Backup Format

Regardless of the repository configuration, the output of the backup process creates resources of the same format. Further details on backup contents and the underlying implementation can be found in ModeShape's documentation.

The backup directory will contain

• 'binaries' directory that contains the repository "content" binaries stored in a pair-tree like structure. The filename of the binary is the SHA-1 of the content with the extension '.bin'. The directory structure in which each binary is found is three levels deep based on the SHA-1.
  

  • For example, binary content in the repository with a SHA-1 of "5613537644c4d081c1dc3530fdb1a2fe843e570170d3d054", would look like 

    ├── binaries
        └── 44
            └── c4
                └── d0
                    └── 44c4d081c1dc3530fdb1a2fe843e570170d3d054.bin

• One or more "documents_00000n.bin.gz" files which contains a concatenated listing of the metadata for each of the repository objects in JSON format

  • For example 

    { "metadata" : 
      { "id" : "87a0a8c317f1e7/jcr:system/jcr:nodeTypes/nt:unstructured//undefined/1" ,

                "jcr.operator.greater.than.or.equal.to" ,

            "mandatory" : false ,
