Backup of CIFS/Samba share

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.

CIFS/Smbclient speed

By default the linux smbclient mounts smb shares using smb protocol version 1.0 (now deprecated). resulting in slow transfer speed against Windows 10 shares. by adding vers=3.0 to you mount options you are using smb protocol version 3.0 with greater speed.

mount -t cifs //192.168.60.202/föreningar "/mnt/share/radion/k2/foreningar" --verbose -o username=backup,password=mypassword,vers=3.0

More info in this stackexchange thread about cifs randomly losing connection to windows share

Set ip-number from commandline

Set Static IP-number

netsh interface ipv4 set address "Extern" static x.x.x.x y.y.y.y z.z.z.z
netsh interface ipv4 add dnsserver name="Extern" address=208.67.220.220 index=1
netsh interface ipv4 add dnsserver name="Extern" address=208.67.222.222 index=2

Extern is the name of your network device
x.x.x.x is your ip-number
y.y.y.y is your netmask.
z.z.z.z is your default gateway.

Enable DHCP

netsh interface ipv4 set address "Extern" source=dhcp
netsh interface ipv4 set dnsserver "Extern" source=dhcp
