The Missing Attachment Scanner performs a background scan on all the attachment files in all projects.
By identifying the missing attachments, it helps to
prevent (unknown) data loss
facilitate data recovery with earlier discovery
identify any underlying issues
reduce the errors logged in Jira backend
fix broken attachments in the Jira issues
Admins can schedule the scanning during off-peak hours
A rescan can also be triggered when required.
With the report on missing attachments, admins can try to reinstate back the missing files or delete the corresponding database records.
For attachments that can be previewed (e.g. images), if the thumbnail is missing, you may spot the following:
Otherwise, if thumbnail is available and the actual attachment is missing, you only detect it when user clicks on it and see the following message:
For attachments that cannot be previewed, you only detect it when user clicks on it and see the 404 message:
It can be accessed from the admin sidebar or via keyboard shortcut g + g.
Since there may be a lot of attachments in the Jira instance, we recommend to schedule the scanning during off-peak hours
Click on the pencil icon for Scheduled Time to adjust the time for scanning
The Scan Status will be updated progressively whenever it has scanned 1 new project
When the Rescan button is clicked, it will trigger a fresh new scan.
Try to locate the file in the quarantine folder or from the backups
Click on the info icon to find the location of the missing attachment
Copy the file back to the location in the Jira server
Verify that the restored attachment can be downloaded from the Jira issue
If the attachment cannot be restored, it will be better to clear the database record with the following steps:
Click on the bin icon to delete the database record of the missing attachment
Click on Delete button to confirm
Ideally, we recommend to do a scan:
before and after a version upgrade
before and after any server migration
