We have UDT's defined and created tags based on these UDT's. There used to be a parameter in a UDT that had its data 'overridden' at the tag level. This parameter no longer exists so we are trying to pull the old values from a backup. These tags are stored in SQL, but I can't find where in the tables the tag parameters would be stored. ---

is it not in TagConfig? ---

Where would TagConfig be? There is no table called TagConfig in the History Provider database. ---

Tag configuration is stored in Ignition's **internal** database, a SQLite file on disk (in 8.1 and prior versions). The historian's tables only store history data. You should not attempt to read or modify the data in this config.idb file; I would recommend contacting support if you want to attempt to recover old data. ---

I found some hints of what I'm looking for in TagConfig in config.idb but I have no clue how this relates back to actual tags. I'll need to pull a backup from further back before I reach out to support because this doesn't have the data I need. ---

> [@Leor\_Fishman](#): > > this is surprising coming from the kindling devs who gave us read queries on the IDB Kindling was originally developed as a tool to aid support reps, and is open source/publicly available precisely for people like _you_ who understand the limits of a support contract and generally know what's "safe" ground to tread on. Kindling is capable of opening _any_ SQLite file, and we use SQLite for the metrics and log file dumps you'll get in a diagnostic backup. That you _also_ get full read access to the underlying SQLite structure is a deliberate choice, but not one that I'd encourage users to exercise carte blanche. ---

Valid, thanks for clarifying
