To mount a Windows file share on Linux, first create the file share on Windows and give the appropriate permissions to the user. Then, on Linux you want to do the following:
Create a directory for the mount point
mkdir -p /mnt/windows/backups
Use the mount command to mount the Windows share:
mount -t cifs //yourwindowsserver/backups -o username=YOURUSERNAME,password=YOURPASSWORD /mnt/windows/backups
Access the Windows share mount point:
cd /mnt/windows/backups ls -l
To make the mount point automount across reboots, you will need to edit the /etc/fstab and add the following entry:
//yourwindowsserver/backups /mnt/windows/backups cifs username=YOURUSERNAME, password=YOURPASSWORD 0 0
