Server Version#: 1.43.0.10492 Player Version#: 4.156.0 I have a failing cache drive in my Unraid server. Trying to back it up prior to replacement I found out that my com.plexapp.plugins.library.db-wal is apparently in the bad area of the disk and won’t backup correctly. I have been experiencing random play failures when streaming music. Maybe related? How important is that file? What will I lose if I simply delete it to get a successful backup? Any words of wisdom regarding this situation? ---

> [@McHawkins\_Library](#): > > my com.plexapp.plugins.library.db-wal This is a kind of “journal”, where the database engine is keeping all the changes that were made to the database in the current session. (that explanation is not 100% accurate, but good enough for our purpose here) It is usually no big deal to just delete ```auto com.plexapp.plugins.library.db-wal com.plexapp.plugins.library.db-shm ``` together, _while Plex server is shut down._ (But of course keep the main file `com.plexapp.plugins.library.db`) You may lose some changes to the database from the last session, but it is rarely something substantial. It might be good to use this [https://github.com/ChuckPa/DBRepair](https://github.com/ChuckPa/DBRepair) afterwards, and avoid major issues before starting up the server again. ---

Oh, great! Deleted those two files, started another backup and now I have a ‘GoP-0.xml’ file failure. Any harm in deleting that? ---

Sorry, no idea where that might come from and what it is for. ---

Took the plunge and deleted that file as well. Plex on the docker is back up and running with no discernable issues or changes. Thanks! ---
