I recently upgraded to v3 (automatically?) and decided to try to add some movies via "collection", I chose something I didn't have or really care about, "Star Wars Lego Collection"

 

After adding, it seems like Radarr thought that was ALL I wanted in my collection and proceeded to delete thousands of movies from its database, and removed 9+TB of files across 2x6tb drives. 

 

I have attached a few most recent logs (i hope there is nothing incriminating), but this excerpt seems to be where I added the list, and Radarr starts deleting my files.

I have pulled the drives and tried to view/recover on my windows machine to no avail. I am now loading an appdata backup and hoping my database can be recovered, and ill just slog through re-downloading everything. 

radarr.0.txt radarr.1.txt radarr.2.txt

I have restored my database now, and I guess I have found the setting that was the issue. 

 

Like I said, i didn't add a list from this screen. and have never used lists before, so I didnt change it to remove and delete files. This cant be the default setting right?  

You should ask that question in the topic specific to Radarr.

 

You can easily find it from the Docker tab with the support link.

 

You're probably right. But to counter, It could be considered a bit more general Radarr issue, than specific to my chosen repo

In that case it should probably be reported in a forum dedicated to Radarr I wound think?  It does not round like an Unraid specific issue.

I guess so, I couldn't find anything for Radarr, so thought this was a good place to post. Ive 'solved' my issue. Please remove if you need to

Where did you search?

I searched this forum, where I am already a member

I know this is an old thread but wanted to say that after recently adding a Radarr docker to UnRaid almost my entire media library plus other files were wiped out and required a restore from backups. Thanks to everyone for keeping this thread around because I was under the assumption that finger trouble and midnight commander were to blame ... until it happened a second time the next day. Searching led me here because of the title. Didn't even know, at this point, that Radarr could be a culprit.

 

Thanks for the pointer to Radarr. Will investigate and take my discussion to a Radarr forum if appropriate.

FYI there is a recycle bin option (not configured by default) for Sonarr/Radarr/Lidarr, which adds a little bit of safety to the media itself.

Yes, thanks. Turned on the recycle bin option for those apps. Also see a CA utility that claims to do the same system wide.

I think that is only for files/folders that are deleted via a Samba network connection.

Everyone should be using "chattr +i" to protect the files that are not expected to be updated or written to.
