Carbonite backup and my floppy drive

Recently I switched to Carbonite on two machines at home.  After installing the software and starting the backup, I noticed that frequently something would be accessing the floppy drive (or at least trying). Googling around a little bit revealed that this was one of Carbonite’s “features”.

The two suggestions that kept coming up during my search were:

  • Insert a floppy, and Carbonite will learn that that drive is a floppy drive
    – Sorry, that didn’t work
  • Disconnect the floppy drive
    – Wait, and then open case when the drive needs to be used? Bad idea!!

There is a third option: disable the floppy drive in Windows.

If you open My Computer, you’ll see something similar to this:

Notice the 3 1/2 Floppy – that’s the one making all the noise. But not for long!

Right-click on the icon, and select Properties from the drop-down menu. Click on the Hardware tab and select the Floppy disk drive.

Click on the Properties button.

On the bottom of the screen is a drop-down box. Click on the drop-down arrow and change the selection to “Do not use this device (disable)”. Click OK.

Click OK on the screen with the 3 1/2 inch Floppy properties, and
return to the My Computer screen. Your Floppy Drive A: should be gone,
and with it the seeking Carbonite tries to do on it!

Ubuntu and the Symantec Backup client

At our company we’re using Symantec Backup Exec to back up all our servers, including some Linux machines. I set up a newer Ubuntu install (9.04) on VMWare, and was pretty confident I would be able to get the backup working (using the Legacy agent). Well, that was not as easy as it seemed…

I followed the instructions on installing the legacy agent. After some tweaking here and there, the server was now showing up in the list of legacy agents on the Backup Exec server. However, every time I tried to pull up information on the server, Backup Exec returned an error, saying the server refused connections and may be running out of available network connections. Nonsense. But something was not right apparently.

Googling around for instructions, and suspecting a firewall or security setting, I tried tweaking access to the ports Backup Exec is using. No effect. Then I hit upon something: luckily I had an older Ubuntu server running with the legacy Backup Exec client, and could compare settings. It turns out that Ubuntu installs a host file with the following content:

127.0.0.1 localhost
127.0.1.1 fqdn.domain.com fqdn

Why is there a difference in the third tuple? On the older server, both lines referred to 127.0.0.1. I decided to change the 2nd line on the newer server to 127.0.0.1 and reboot. After giving everything some time to publicize itself on the network, it appeared and asked for the credentials to use for the new server. I selected the correct user, and to my astonishment, the complete directory structure appeared.

I don’t know why there are two different entries for the local machine, but it definitely broke the legacy Backup Exec client. Now I can only hope I never have use our backups…!
