             Summary: Incremental Backups fail following a splitshard op
                 Key: SOLR-15696
                 URL: https://issues.apache.org/jira/browse/SOLR-15696
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: Backup/Restore
    Affects Versions: 8.9
            Reporter: Jason Gerlowski
            Assignee: Jason Gerlowski


Filing this ticket on behalf of a reporter on the mailing list (Jordan Diehl) who had trouble filing it themselves. See the "Can't create solr jira bugs" thread for more context.

"I have been attempting to use the incremental backup API on Solr 8.9.0, but while testing in our product we would occasionally get into a state where all subsequent backup attempts would fail. After some triage we found that it was happening to any collection which had undergone a shard split operation. If we did a backup, completed a shard split operation, then attempted another backup, the second backup would fail with a FileNotFound exception relating to the backup id of the second backup as the error message."

*Steps to Reproduce:*

Run the script found here in a clean 8.9.0 download. In essence, it (1) creates and fills a collection (2) performs a backup (successfully), (3) splits a shard in the collection, and (4) triggers another backup (which fails).

*Expected Behavior*

"If this operation is being blocked intentionally, then I would expect an informative error message explaining why it failed. Otherwise I would expect the backup to complete successfully."

*Actual Behavior*

"The backup operation fails with a NoSuchFileException."
