MySQL Error 3871: Clone Loopback Connection Error
Description
This error indicates an attempt to perform a MySQL cloning operation where the source and destination directories are effectively the same, or the cloning process tries to use a 'loopback' connection to clone data into its own current data directory. MySQL prevents this self-referential cloning to avoid data corruption and logical inconsistencies.
Error Message
Clone cannot use loop back connection while cloning into current data directory.
Known Causes
3 known causesIncorrect Destination Path
The cloning command or utility was invoked with a destination path that points to the server's currently active data directory.
Self-Referential Cloning Attempt
The cloning operation implicitly or explicitly tries to clone the database's data into the very same location from which it is currently running or being sourced.
Misunderstanding Cloning Purpose
The user might be attempting to 'refresh' or 'backup' the current directory using a cloning mechanism, which is not its intended use.
