I've used Acronis True Image on quite a large number of Windows systems over the years, as it is a very good product which has gradually expanded it's (already impressive) feature set throughout that time. Just recently, I had the requirement to image a Linux system and so decided to trial the new Acronis True Image Echo Server on Linux - from what I found, there is no 'workstation' product for Linux like the True Image Home product for Windows, and so had to go for the server version instead. Specifically, I needed to backup a 64-bit CentOS 5.1 virtual machine running inside Citrx XenServer Express.
After registering for the trial version on Acronis.com, downloading the appropriate installation file and moving it into the VM, a quick 'chmod +x TrueImageServerEcho_d_en.i686' made the file ready for installation. The binary is suitable for 32-bit and 64-bit systems - no need for seperate installation files.
After kicking off the installation ('./TrueImageServerEcho_d_en.i686'), it was pretty much a next-next-finish affair, except I soon found I needed to have the kernel source files and gcc installed, for the installation program to correctly configure the SNAPAPI Module. A quick 'yum install -y kernel-xen-devel gcc' fixed the dependancy issue, and after re-run of the True Image installation file, all required software was now installed.
By the way, there was no documentation supplied with the downloaded installation file; I found out some of the information on the Acronis website, and also by browing the setup log file (/var/log/trueimage-setup.log).
Since I don't generally use an X-Windows interface on *nix systems (much prefer the command line via SSH), I've now got to see how far I get with the console tools ('trueimagecmd' and 'trueimagemnt')...
