Eflibrary file not backed up by Backblaze

pretty self-explanatory, I think. The mbox files and everything else (folders, etc) seems to be backed up, but not the eflibrary file. Has anyone encountered this and know of a workaround? It was not obvious to me it was based on any exclusions in the Backblaze preferences.

I would not expect Backblaze to exclude .eflibrary packages if you had told it to back up the containing folder. EagleFiler does not mark them as excluded from backup, or anything like that.

That’s what I expected also. I have submitted a help request to Backblaze staff.
