datalad export-archive-ora [-h] [-d DATASET] [--for LABEL] [--annex-wanted FILTERS] [--from FROM
    [FROM ...]] [--missing-content {error|continue|ignore}]
    [--version] 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 keys 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 or value must be NONE

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) or value must be NONE

--for LABEL

name of the target sibling, wanted/preferred settings will be used to filter the files added to the archives. Constraints: value must be a string or value must be NONE

--annex-wanted FILTERS

git-annex-preferred-content expression for git-annex find to filter files. Should start with ‘or’ or ‘and’ when used in combination with –for.

--from FROM [FROM …]

one or multiple tree-ish from which to select files.

--missing-content {error|continue|ignore}

By default, any discovered file with missing content will result in an error and the export is aborted. Setting this to ‘continue’ will issue warnings instead of failing on error. The value ‘ignore’ will only inform about problem at the ‘debug’ log level. The latter two can be helpful when generating a TAR archive from a dataset where some file content is not available locally. Constraints: value must be one of (‘error’, ‘continue’, ‘ignore’) [Default: ‘error’]
