DSM-G600, DNS-3xx and NSA-220 Hack Forum

Someone responded to a thread of mine suggesting rsnapshot and I was wondering if anyone had any experience with this tool on the DNS-323.

It says it needs rsync (got it), perl (does the DNS-323 have it by default?), ssh, du and logger.  I think it has everything but perl, can anyone confirm?

Can someone tell me if 3.1 below is DIFFERENT than 3.2 and beyond?  In other words, are they just two ways to install it?  Or do you have to do 3.1 & 3.2...and on?

3.1. 30 second version (for the impatient)

./configure --sysconfdir=/etc
su
make install
cp /etc/rsnapshot.conf.default /etc/rsnapshot.conf

The rest of this section is the long version.
3.2. Untar the source code package

tar xzvf rsnapshot-1.2.0.tar.gz

If you don't have GNU tar, you may have to do this in two steps instead:

gunzip rsnapshot-1.2.0.tar.gz
tar xvf rsnapshot-1.2.0.tar

3.3. Change to the source directory

cd rsnapshot-1.2.0/

3.4. Decide where you want to install

By default, the installation procedure will install all files under /usr/local. For this tutorial, this will be OK except we will install the config file under /etc.

We are assuming that rsync, ssh, logger, and du are all in your search path. If this is not the case, you can specify the path to any of these programs using the typical Autoconf --with-program=/path/to/program syntax. For example, if Perl was in /opt/bin/perl and rsync was in /home/me/bin/rsync, you could run configure like:

./configure --with-perl=/opt/bin/perl --with-rsync=/home/me/bin/rsync

3.5. Run the configure script

This will poke and prod your system to figure out where the various external programs that rsnapshot depends on live. It also generates the Makefile that we will use to install the program. The configure script accepts arguments that can be used to tell it where to install the program, and also where to find the supporting programs. For this installation, the only non-default option we want is to put the config file in the /etc directory. To do this, run this command at the shell:

./configure --sysconfdir=/etc

If all goes well, you're ready to install the program. If there was a problem, it should be descriptive. Most likely a problem would be the result of something that was required and not found (like rsync or perl). If this happens, you must figure out where the missing program is located on your system, or install it if necessary. If you know where it is but configure couldn't find it, you can specify the path using the --with-program=/path/to/program options described above.
3.6. Install the program

If you've followed these instructions so far, you will have configured rsnapshot to be installed under /usr/local, with the config file in /etc. Under these circumstances, it will be necessary to become root to install the program. Now is the time to do so. You will, of course, need the root password to do this:

su

This will prompt you for the root password.

Now, to install rsnapshot, run the following command:

make install

This will install rsnapshot with all the settings you specified in the ./configure stage. If all goes well, you will have the following files on your system:

/usr/local/bin/rsnapshot The rsnapshot program

/usr/local/man/man1/rsnapshot.1 Man page

/etc/rsnapshot.conf.default The example config file

If you decide later that you don't want rsnapshot on your system anymore, simply remove the files listed above, or run make uninstall in the same source directory you installed from. Of course, if you installed with different options, the location of these files may be different.
