By mounting a smb share on your linux machine you can make an rsnapshot of the entire share without installing cwrsync. example below

1. Download ds_smbmount
2. Create a script that mounts all samba shares you want to snapshot.  the script should exit with an exitcode > 0 if mounting fails.  Script is later refered to as /root/smb/radion-mount

   #!/bin/bash
   
   /root/bin/ds_smbmount -d "/mnt/share/radion/k2/foreningar" -s "//192.168.60.202/föreningar" -u backup -p mypassword -U 0 -G 1003
   if [ $? -ne "0" ]; then
    echo "Failed to mount /mnt/share/radion/k2/foreningar"
    exit 1;
   fi;

3. Create a script that umount all samba shares after your rsnapshot is finished. script is later refered to as /root/smb/radion-umount

   #!/bin/bash
   
   umount /mnt/share/radion/k2/foreningar

4. Configure rsnapshot to run an script before and after snapshot.
