Tutorial: Uranium Backup e ClamWin, per backup al sicuro dai virus

Virus-safe backups with ClamWin Free Antivirus

This simple tutorial shows how to integrate Uranium Backup with the well-known antivirus software ClamWin (http://www.clamwin.com). ClamWin is an open source software and can be used freely also for commercial purposes.

The first thing to do, obviously, is to download ClamWin from its download page: http://www.clamwin.com/content/view/18/46/ and install it on your PC where you want to make backups with Uranium.
Due to ClamWin does not include an on-access real-time scanner, it can coexist without any conflict with other antivirus software already installed on the same system.

Using the command line utility of ClamWin you can scan and remove viruses every time you perform a backup with Uranium.

We see below how to create a simple batch file, which we will call "antivirus_scan.bat", to start ClamWin antivirus scanning, and how to run it through a simple Uranium's option.
The contents of the batch file might be as follows:

"C:\Program Files\ClamWin\bin\freshclam.exe" --datadir="C:\Documents and Settings\All Users\.clamwin\db" --config-file= "C:\Program Files\ClamWin\bin\freshclam.conf"

"C:\Program Files\ClamWin\bin\clamscan.exe" --database="C:\Documents and Settings\All Users\.clamwin\db" --recursive --move="C:\quarantine" --unzip="%TEMP%" --unrar="%TEMP%" "C:\mybackupsourcedir"

We can see two commands: the first is optional and serves to update the antivirus before scanning (the PC must be connected to the Internet), the second serves to perform the antvirus scanning. They are executed the programs freshclam.exe and clamscan.exe, that are located in the "bin" folder in the installation directory of ClamWin.

For the first command (freshclam.exe), we must specify the following parameters:

-- datadir: this is the path of the virus definitions database. In Windows NT, 2000, XP, 2003, this path is by default: C: \ Documents and Settings \ All Users \. Clamwin \ db

-- config-file: the path of a small configuration file that mus be created manually by us.
We called this file freshclam.conf (we can put it in any folder) and put inside the following lines:

DatabaseMirror database.clamav.net
MaxAttempts 3

For the second command (clamscan.exe) we must specify the following parameters:

-- database: this is the path of the virus definitions database. In Windows NT, 2000, XP, 2003, this path is by default: C: \ Documents and Settings \ All Users \. Clamwin \ db

-- recursive: Make scanning also in subfolders

-- move: move infected files to the specified folder (if you want to delete immediately infected files you can replace this parameter with --remove)

-- unzip --unrar: enables the scanning of compressed archives

As last parameter we have to specify the path of the folder we want to scan. If we want to scan more than one folder we will have to repeat the second command for each folder.

Configuring Uranium for the execution of the batch file before the backup:

Let's click on Backup Set options:

Then let's go in the panel "Other" and set up the option like we can see in the image below:

Let's check the option "Run a program or a file:"

With the "Select" button we can select the batch file we've just created.

Then we must check the option "Wait for the end of the execution up to a maximum of ..." and set the maximum time that we believe is necessary for the whole virus scanning (and for updating if we put this command in the batch file). The program will wait for the end of scanning up to the maximum time before start the backup.

Checking the option "Visible" we will see a dos window with the scanning log.

To make effective this configuration we will have to click on "Apply".

Note: this procedure can be used with any other antivirus software that has the possibility to be run from command line.
