Hi Dw,
Instead of being able to create a backup while indexing - e.g.: /Admin/Public/IndexUpdateTask.ashx?Path=Results&FullUpdate=True&CreateBackup=True
Then it would be great if the indexing process could happen in a temporary directory and when finished replace the current index with the temporary index.
This will mean that the index (almost) not will be unavailable while indexing a large index.
At least the index should be restored from the backup if the indexing process fails.
Best regards, Anders
