It's a relatively simple version control system so it works great for an individual or small team (less than 10 people). But if you have a medium to large team, especially one with members distributed over a large geographic area, or one where individuals need to be able to work "offline" without access to a central server, Apache Subversion will likely not be the best choice.
Also, if you're maintaining an open-source project where outside people will be interacting with your code repository, git is probably a better choice because it's becoming the de-facto standard these days and what most developers are familiar with.
As any other archiving solution, it is very well suited for environments with a large footprint of unstructured data (CIFS / NFS shares for user data) with a large amount of unused/old files and a need to keep those unused files for long term. In our scenario, due to some legal and contractual constraints we need to keep these files for 15 years. Archiving is a good choice to move the unused files to a cheaper storage tier, both on-prem or cloud.
Distributed development - I've never worked in an environment where distributed development (developers widely scattered geographically) was a factor, but that's why git exists.
Merging - Merging of code from one branch to another can be painful, especially if it's not done frequently. (On the other hand, doing merges is one of the reasons I get a nice salary, so I can't complain too much!)
Acceptance - Let's face it, git is what "all the cool kids are using." If you've got a bunch of developers fresh out of school, they'll probably know git and not Subversion.
While there are interesting alternatives, such a GIT, Subversion has been a breath of fresh air compared to its predecessors like CVS or Microsoft Source Safe (now called Team Foundation Server). Its ease of use and high adoption rate is going to keep me using this product for years to come.
Git has become the new standard of version control, with its support for distributed design. As a tool to manage and control versions, Subversion does it well, but Git is the future.
We have used Veritas Enterprise Vault in the past, and besides its being a well-known player on the data archiving market, their tool is far more complex to implement, to manage and to keep working. Komprise is very robust and also very easy to implement, as most part of the job is done on Komprise side. The management console is delivered through a public URL as a SaaS platform. You only need to deploy a few VMs for scan/archiving/user access, which they call "Observer VMs." Komprise also doesn't uses Stub files, which is a poor implementation adopted by the competitor for file access. We had a lot of issues in the past with stub files. Komprise has implemented 'bread crumbs', which are CIFS symlinks to the files on the Observer. It is a very good implementation and it works really well.
