How do open source backup tools stack up against software from the bigger vendors in terms of functionality today?
There are a number of open source backup applications that you can use to protect your organization. Some of the more advanced open source products offer feature sets that are comparable to those found in commercial backup applications. Although there is nothing wrong with using an open source backup product, there are a number of things to consider before doing so.
One of the most important considerations is support. While telephone-based support typically is available for commercial backup software, that isn't usually the case for open source software. Open source software is usually community supported, which means that you will have to search the message boards for help.
Another consideration is that some open source utilities are downloaded as Linux packages. In these situations, you will have to compile the application yourself before you can use it. Rather than being able to run a simple Windows Setup program, you will have to use a compiler such as GCC to assemble the package. Once it's assembled, you may have to run the software on a Linux server or use a utility such as Cygwin to make it run under Windows (in a Linux-like command environment).
The biggest trick to using open source backup software is to get it up and running. After doing so however, a good open source backup application will likely deliver all the functionality that you need. Many open source backup tools support things like deduplication and virtualization. Before settling on an open source backup product, however, make sure that it offers Windows application awareness (some don't).
