+===== Installing Extra Perl Modules =====
+When I first made this page, I didn't remember having to do this step, but I've since set up another DNS-323 for someone else and I had to do this.  So I think these steps are required.  Let me know of the forum page if you find differently.
+So let's install File::RsyncP and Compress::Zlib.  Compress::Zlib isn't required and I haven't used it or tested it because my drives are large enough that I don't really need the compression.  One of these days I'll test it out I'm sure.
+The page for File::RsyncP is located [[http://search.cpan.org/dist/File-RsyncP/lib/File/RsyncP.pm|here]] and here's the steps for installing:
+  cd /mnt/HD_a2/ffp/tmp/
+  wget http://search.cpan.org/CPAN/authors/id/C/CB/CBARRATT/File-RsyncP-0.68.tar.gz
+  tar zxvf File-RsyncP-0.68.tar.gz
+  cd File-RsyncP-0.68/
+  perl Makefile.PL
+  make
+  make test
+  make install
+The same is done for Compress::Zlib located [[http://search.cpan.org/~pmqs/Compress-Zlib-2.011/lib/Compress/Zlib.pm|here]],
+but you're going to have to install all of the prerequisites as well:
+  Compress::Raw::Zlib
+  IO::Compress::Base
+  IO::Compress::Base::Common
+  IO::Compress::Gzip
+  IO::Compress::Gzip::Constants
+  IO::Uncompress::Base
+  IO::Uncompress::Gunzip
+I don't think this is difficult, just time consuming. However, if you're lazy and trust the perl automatic installer, you can run:
+  for N in Compress::Raw::Zlib IO::Compress::Base IO::Compress::Base::Common IO::Compress::Gzip IO::Compress::Gzip::Constants IO::Uncompress::Base IO::Uncompress::Gunzip
+    do perl -MCPAN -e "install $N"
+  done

-I think I've missed some of the questions that come up in this next section, such as the ones about compression.  I didn't enable compression since 500 GB (on RAID 1) is well enough for me and I wasn't sure how well the DNS-323 would handle doing compression, but I suspect it would handle it well enough.  Also, most of my files are jpeg images which aren't going to receive much benefit from compression.  So enable it if you like and give us your results at the bottom!
+Some of these questions will be different if you have a previous install.  If you have a previous install and you're trying to complete redo everything, you need to remove you old /etc/BackupPC/config.pl file.

 ===== Troubleshooting =====
-"unknown host" error when starting a backup
+== "unknown host" error when starting a backup ==
 This can happen if you have added a host to conf/hosts but forgotten to reload the config file.
+Also, if you have a computer named computer1 and you can't do a ping computer1 and get a correct response (from the correct IP address), you may need to statically assign computer1's IP address (on computer1's machine) and then set up your /etc/hosts file give the IP address for computer1.
+So edit the /etc/hosts file to add:
+.168.xxx.xxx computer1 computer1
+And to make this work on startup add to the end of your fun_plug file:
+  echo "192.168.xxx.xxx computer1 computer1" >> /etc/hosts

+== backup aborted (inet connect: Connection timed out) ==
+Connection is blocked on firewall or rsyncd on client computer is not running.
+== restore failed (Unable to read 4 bytes) ==
+To fix this change read only = false in c:/rsyncd/rsyncd.conf file on your client computer.
+I tested it and it works on Windows XP Home and Professional.
