+Hello and welcome to another episode of Packup Public Radio.
+I'm DeepGeek and this episode was originally recorded in April of 2008.
+This episode is a software review of Fallbackup and is part of our series on lightweight applications.
+The lightweight application series is open to all HPR contributors and is OS agnostic.
+Fallbackup is a command line backup tool developed at Friedrich Alexander University in Erlengen Nuremberg.
+Fallbackup is interesting for two reasons.
+The first is that command line nature is particularly given to automating backups.
+And the second reason is that its way of backing up files creates a really easy to use system of versioning.
+First, command line. Upon installing Fallbackup, I was immediately impressed
+in that automatically inserts a script into the Etsy Kron.Daily folder, which gets run daily.
+The script has the default directory is commented out.
+So all I had to do was delete the hash symbol and voila, instant daily backup.
+It was that easy.
+By default, all the defaults can be overwritten by adding the Fallbackup.conf file in the Etsy directory.
+It writes backups to a directory called slash backup.
+You can create this in the root directory or create a partition for it.
+Simply by doing so and pointing the Etsy FS tab file to the appropriate place.
+What I did personally is I bought a spare hard drive and installed it on a separate controller
+than my main disk.
+I then set the disk to go into standby in about half an hour of no use.
+For me, this is a good thing because I want to protect myself against my main disk failing.
+Also, since the second disk is used only rarely, it simply is not used as much as the main disk.
+You can also do a few advanced things with the target of your backups.
+For instance, it will accept the backup directory being on an NFS share just fine.
+But you do have to tell the NFS server to accept this machine's root user as a root user on its system.
+You can also backup over SSH or RSH. The flexibility is there.
+But it really made me fall in love with full backup though, is the way it stores the files it backs up.
+Full backup in its default configuration creates a file structure where for each machine and each major directory,
+it creates a sub directory with a date stamp and copies all the files into that directory.
+Now, you may be thinking, wait a minute, that's a lot of files for a daily backup.
+But does not store all those files.
+Most Linux file systems support what is called hard links.
+Basically, if a file is unchanged, full backup creates a hard link to the file.
+Full backup maintains by default, but you can override this if need be.
+Two annual backups, 12 monthly backups, and four weekly backups.
+Now, if a file is never changed, full backup will store one instance of the file and create 18 links to the same file.
+So the file will be stored once and will appear in many different directories.
+Also, full backup takes advantage of sparse files, which means that if the file has blocks of null space, that space will be saved.
+So, let me tell you what it's like to retrieve a file from backup with full backup.
+It creates a regular file system, which means any method you want to use to get a file back will work.
+You can use regular batch file management tools like LS and CP.
+You can use a favorite graphical file manager like Rocks, Nautilus, Conqueror, Dolphin or Midnight Commander 2.
+If you have FTP or SFTP surface, you can also pull files through that also.
+This is all because it uses regular plain Linux files, so anything works on it.
+If you want, they have a source for its site at filebackup.sf.net.
+Let me set it phonetically.
+Foxtrot Alpha Uniform Bravo Alpha Charlie Kilo Uniform Papa Dot Sierra Foxtrot Dot.
+November Echo Pango.
+You can preview the manual pages there, as well as make inquiries by emailing their mailing list.
+If you decide to try it, I hope you will enjoy it.
+Today's geek tidbit, let's have a little geek haiku.
+Wily Quick Page eludes you handsomely.
+Smack that mouse harder.
