I am using the Ubuntu aic7xxx module (which is controlling an Adaptec 21960 scsi controller which in turn is connected to a Dell LTO tape unit). I have successfully installed deja-dup and duplicity. What I am trying to do is to verify that the scsi controller and LTO drive are being recognized by Ubuntu. Question: Deja-dup does locate any devices, only folders/drives (there are two hard drives). Is duplicity/deja-dup only for use with folders/directories? If they are, is there a list of Ubuntu supported back-up software that is newer than 2014 (Comparison of backup tools) that Ubuntu supports somewhere? I ask because I know that as software develops, what works in 2014 may not be supported in 2016.

This is a two step process. First, you need identify the the Dell LTO scsi tape drive as recognized by the computer. Second, you need to mount the device as a folder/directory.
First Step: Find the device
To list all the scsi devices, you need a tool called lssci. You may need to install this first. Open a command line by pressing Ctrl+Alt+T and enter:
sudo apt-get install lsscsi
Enter your password when prompted. The cursor won't move while you enter your password. That is normal. Once lsscsi is installed, enter the command:
lsscsi -l
This will list your SCSI devices like the DELL LTO. It will look something like /dev/st0. /dev is a special virtual folder for devices in Linux. The devices listed there needs to be mounted on a regular folder before they can be used by any program like Deja Dup.
Second Step: Mount the device
Ubuntu mounts devices that are not always connected under the folder /media/. First, see if the device is already mounted there or not. It will be something like /media/Dell_LTO. If this is so, we are almost done. If not, you need to first create the Dell_LTO folder under /media/ by the following command:
sudo mkdir /media/DELL_LTO
You will need to do this once only. Once the actual folder is created, you will have to tell the computer to use that folder as the mount point for the Dell LTO devise.
sudo mount /dev/st0 /media/DELL_LTO
Here I have used DELL_LTO as an example. You can call this folder whatever you want. Remember Linux is case sensitive. So a folder call DELL_LTO is very different from a another folder called dell_lto, or dEll_lTo.
Hope this helps
