HOW TO: Install TSM Client on Debian/Ubuntu 64bit Server
Few weeks ago, I had the task to install TSM Backup Client, in a Debian 64bit Server. TSM was developed by IBM. With the use of this software you can create schedules for automatic Backups to a central/main Backup Server. Sadly IBM decided not to support Debian and derivatives, so that is how we come to the first problem: It is “impossible” to install TSM in a Debian machine. But with some few tricks, you can install it and run it as if IBM had support for Debian. The second problem is: we are dealing with a 64bit Server (actually this is not a big deal, but nevertheless things get a bit more “complicated”). This is a HOW TO install TSM Client on Debian/Ubuntu tutorial [social_share style=”circle” align=”horizontal” heading_align=”inline” text=”” heading=”” facebook=”1″ twitter=”1″ google_plus=”1″ linkedin=”1″ pinterest=”1″ link=”” /] So first of all you should have the following archive and packages: 6.1.3.4-TIV-TSMBAC-LinuxX86.tar alien libstdc++6 ksh ia32-libs For installing alien, libstdc++6 and ksh: [code]~# apt-get install alien libstdc++6 ksh ia32-libs[/code] Now you have to unpack the file with the following command: [code]tar xvf 6.1.3.4-TIV-TSMBAC-LinuxX86.tar[/code] Go to the file that was unpacked from the previous step: [code]cd TSM[/code] You will have the...
