So many connect and disconnect records between samba server and backup server

B

Hi,

On a samba server, 192.168.1.254, I have following lines in /etc/crontab to replicate storage to a backup server, 192.168.1.151.
Code: 
30    22    *    *    1-6        root    zxfer -dFkPv -I keylocation,keyformat,pbkdf2iters -T root@192.168.1.151 -R zroot/jtanks/samba/store1 backup/samba
30    23    *    *    1,3,5        root    zxfer -dFkPv -I keylocation,keyformat,pbkdf2iters -T root@192.168.1.151 -R zroot/jtanks/samba/store2 backup/samba

I just checked the /var/log/auth.log on the backup server, and found many connect and disconnect records between samba server and backup server at the time of scheduled replicating. Is this normal?
