Now I realized that there is no /var.
Sorry, I don't know where OpenWrt's DB vnstat is located.

6

Checked /tmp ?
That would be the logical location, to avoid flash wear.

/tmp is ram, you reboot, it's gone.

How can I store this database?
My router does not have a USB port.

Sorry, you wrote store, not restore.

As I said, network storage, like a file share.

Mount it as any other drive in Linux, on the router, put the DB there.

I use linux, my machine:
IPv4: 192.168.1.101
IPv6: 2804:29b8:509d:dd5a::42b

How can I do this by selecting my machine?

Just make sure the mount is there before you attempt to start vnstat, or you'll end up writing the file in the wrong spot.

Ideally put the mount point somewhere in /tmp, if the mount would fail, you still won't kill your flash with writes.
