Proxmox backup in NAS SYNOLOGY

Hello everyone

after configuring that my proxmox server connect to a Synology NAS via (SMB/CIFS) , and created backup job , checking my NAS LOG found that inside overview > last 50 logs
each 30 seconds i get in the LOG :
INFO
User [bkuser] from [PROXMOX(192.168.x.x)] via [CIFS(SMB3)] accessed shared folder [bk_server].

any one faced this ?
