I have a very high frequent used samba server. The Problem is that when I stop the smbd.service sometimes, I can not really reproduce it, instead of subdirectories on the share, files appear with \ in the filename.
For example:
the share is '/data' and there are some subdirectories like '/data/content/test/mine' or '/data/someothercontent/shared/or not'. And as mentioned above, when I stop smbd then files like this appear:
- /data/content\test\mine\somefile.txt
- /data/someothercontent\shared\ornot\someotherfile.txt
