datalad export-archive-ora [-h] [-d DATASET] TARGET ...


Export an archive of a local annex object store for the ORA remote.

Keys in the local annex object store are reorganized in a temporary directory (using links to avoid storage duplication) to use the ‘hashdirlower’ setup used by git-annex for bare repositories and the directory-type special remote. This alternative object store is then moved into a 7zip archive that is suitable for use in a ORA remote dataset store. Placing such an archive into:

<dataset location>/archives/archive.7z

Enables the ORA special remote to locate and retrieve all key contained in the archive.



if an existing directory, an ‘archive.7z’ is placed into it, otherwise this is the path to the target archive. Constraints: value must be a string

list of options for 7z to replace the default ‘-mx0’ to generate an uncompressed archive.

-h, --help, --help-np

show this help message. –help-np forcefully disables the use of a pager for displaying the help message

-d DATASET, --dataset DATASET

specify the dataset to process. If no dataset is given, an attempt is made to identify the dataset based on the current working directory. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path)
