Supports backup/restore of all local DSpace Configurations and Customizations

Yes (if you backup your entire DSpace directory as part of backing up your files)

Not by default (unless your also backup parts of your DSpace directory – note, you wouldn't need to backup the '[dspace]/assetstore' folder again, as those files are already included in AIPs)

Issue / Error Message

How to Fix this Problem

ingest

Ingest/Restore Error: "Group Administrator already exists"

If you receive this problem, you are likely attempting to Restore an Entire Site, but are not running the command in Force Replace Mode (-r -f). Please see the section on Restoring an Entire Site for more details on the flags you should be using.

ingest

Ingest/Restore Error: "Unknown Metadata Schema encountered (mycustomschema)"

If you receive this problem, one or more of your Items is using a custom metadata schema which DSpace is currently not aware of (in the example, the schema is named "mycustomschema"). Because DSpace AIPs do not contain enough details to recreate the missing Metadata Schema, you must create it manually via the DSpace Admin UI. Please note that you only need to create the Schema. You do not need to manually create all the fields belonging to that schema, as DSpace will do that for you as it restores each AIP. Once the schema is created in DSpace, re-run your restore command. DSpace will automatically re-create all fields belonging to that custom metadata schema as it restores each Item that uses that schema.
