I have Retrospect Linux Client 7.5.112 running with Ubuntu 7.04.
I first made sure that my Ubuntu Client Machine could communicate with the Window XP machine by reading a file from a shared folder.
Installed Bootup-Manager via Automatrix.
From Terminal prompt, I ran "sudo apt-get install alien" (used to convert the rpm file to deb)
From Terminal prompt, next you want to run " sudo alien -d -c retroclient-75_linux.rpm" to convert rpm file to a deb file
Next I went in via Natilus and loaded the Deb file via the GDebi Package Installer. It prompts for an access password.
Next I went into Bootup-Manager (System, Administration) and put a check next to "rcl" to allow client to load during startup.
Other than normal Retrospect setup, I used the "Sbackup" (loaded thru Automatix) as a template on what to backup. I delete "Sbackup" afterwards thru Automatix.
I am backing up my Ubuntu files with Retrospect 7.5 server for Windows.
