VnStat multiple errors in system logs

Installing and Using OpenWrt

Hi guys

recently I setup VnStat with Luci support on Openwrt 18.06.1. All went good, it works nice but today I looked into system log and there is an error every 5 seconds. It looks like that:

Sat Sep 22 12:27:11 2018 daemon.err vnstatd[2946]: Error: Unable to open backup database "/mnt/usb/.lost+found": No such file or directory
Sat Sep 22 12:27:16 2018 daemon.err vnstatd[2946]: Error: Unable to open backup database "/mnt/usb/.lost+found": No such file or directory
Sat Sep 22 12:27:21 2018 daemon.err vnstatd[2946]: Error: Unable to open backup database "/mnt/usb/.lost+found": No such file or directory
Sat Sep 22 12:27:26 2018 daemon.err vnstatd[2946]: Error: Unable to open backup database "/mnt/usb/.lost+found": No such file or directory
Sat Sep 22 12:27:31 2018 daemon.err vnstatd[2946]: Error: Unable to open backup database "/mnt/usb/.lost+found": No such file or directory

I was trying to look into /etc/vnstat.conf but I don't see there any option regarding backup. Could help me guys to sort out the issue? Thank you.

I figured it out. Path to USB drive cannot be just where you mount it. I had to create folder on that drive and move DatabaseDir to that particular folder. No input in log files since change.
