why I lost a sprint but the task going back to backlog?

[Hilda Esartha]

i didn't complete the sprint nor closed it, but then suddenly it disappear by itself. How come this is happening? and why all the task got back to backlog?

Hello Hilda,

Welcome to Atlassian Community.

I must confess that I'm not aware of any occurrences where the Sprint simply disappeared from the JIRA project, so I believe you must be facing some of the behaviors below:

1 - Someone else has deleted or completed the Sprint:

If the Sprint was completed, you will be able to see it in the Sprint Report of the project, supposing you remember the name of the Sprint.

2 - By accident, you may have deleted or Completed the Sprint

3 - If you are using JIRA Server, you might be facing any database issues that might have deleted the Sprint: 

This is the less probable possibility, however, can you let us know if you are using JIRA Server or Cloud? We may provide you the steps you can take to access the logs and check what could have happened to the Sprint.

4 - if all there are no issues in that project that is added to the Sprint you created, the Sprint might disappear only from the board view, depending on the project type you are using. Can you confirm if when you click on the Sprint field of any issue it returns the Sprint you configured previously?

Let me know if this information helps.

it's not completed yet, that's why I couldn't see the sprint report. if I delete it, could it be somehow the task back to backlog? I don't think so. 

I didn't use JiRA server. 

thanks

Hi Hilda,

I understand that you did not complete a sprint, but that you still noticed an issue that was in that sprint has returned to the backlog and that sprint it gone.

What I suspect has happened is that another user with the manage sprint permission could have closed this sprint.  Since sprints can appear on multiple boards at the same time, it is possible that another user on the same board, or on a different board that contains that same sprint could have closed the sprint.  And if that issue was unfinished, that user could choose to put that issue into the backlog or into a future planned sprint that appears on the board which they did this from.

I would suggest going into the reporting section of your board to see which user closed this sprint.   You can do this by going to the Board, then on the left navigation bar select the Reports section.  Then select the Sprint Report.  From there you can select the sprint name in question, and that page should then tell you specifically which user closed that sprint.  

I hope this helps.

thanks Andy, that might happen since there are different board that contains same sprint
