After fixing an incorrect metadata match, what should I lock?

[podonnell 47]

Hi,

I had a series misidentify for the first time. I did an 'identify' to fix it, and it's good now. However, I use the setting to refresh metadata every 90 days, so I don't want it to go back to the incorrect series in 90 days.

If I lock a specific value on the series, such as the Title, will that prevent a bad match?

Once you use the 'Identify' function, you're effectively updating the provider Ids for that item (eg. TMDB or TVDB, etc)

Refreshing that item in future will still use the same provider Id, so you won't have any issues with it being identified incorrectly again, you will just get any updated metadata that has changed since you last refreshed.

No need to lock anything.

Only way this could change is if you do not write nfo files and your media libraries go offline and Emby purges the library metadata.  But nfo is written it will always be reread.

I don't write NFO files for most of my libraries. What would cause this?

You can search the forum and see multiple topics where user shares or mounts are unavailable when Emby starts or does library scans and Emby purge the Database for that library as it is reporting Empty at the time.

Here is one

Interesting. I have local disks but want to think ahead in case I ever do have something like this happen.

So if it deleted the metadata, only in the situations where I have my own manual changes would I lose information?
Could I restore or browse the database to retrieve this info and restore it perhaps?

Otherwise turning on NFO files is something I suppose I could do if that is recommended.

I appreciate the heads up on this!

As long as you have a database and metadata folder backup of before it happened you will be fine as you can restore.  If you don't then you have to wait on Emby to refetch all metadata and images.

 

Personally store metadata and images with media so Emby does not technically have to do anything but read on a rebuild if needed.  If you are database only metadata/images something happens to that database you could loose everything and have to start over.  

One reason you should have the backup and restore plugin maintain multiple copies of the databases as it only maintains one full backup which you can still loose everything depending on when the issue happens as if there is a issue around the same time as a backup kicks off you will loose content from the metadata folder ie images per item.

It is always good to have your own backup plan outside of Emby.

Had another instance of a bad match tonight. Not sure why it matched the series it did, but I did an identify and I -think- i can safely move on. 

I am set to 30 copies of backups, and I understand worst case scenario would be needing to restore some metadata for things I’ve manually changed. 

I am revisiting the idea of saving metadata to NFO files; but I’m not well versed on the side effects of this.
