# resume all uploads in the given postprocessing step 
POSTPROCESSING_STEPS = virusscan  (if you find other steps eligible then please add)
> ./ocis/bin/ocis postprocessing resume                # Resumes all uploads where postprocessing is finished, but upload is not finished
> ./ocis/bin/ocis postprocessing resume -s "finished"  # Equivalent to the above
> ./ocis/bin/ocis postprocessing resume -s "virusscan" # Resume all uploads currently in virusscan step

How to obtain failed upload

• set POSTPROCESSING_DELAY env and upload resources, and while uploading, restart ocis service using ocis-wrapper. This way you get an unfinished upload
• If you have alternative, then you can use that also

Test coverage

• resume-specific failed upload
• Restart postprocessing for a specific upload
• Resume all failed uploads
• Resume all failed uploads which is at postprocessing step finish
• Resume all failed uploads which is at the postprocessing step virusscan
