> "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|https://paste.apache.org/o4uta] 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."
