K's Software Pick! Veeam Agent!
One thing that really annoys me is a certain lack of flexibility in MS land backups.
Apple have Time-machine which is really nifty and this can to a certain degree be emulated on Windows with a cost (usually).
But that's not what Kay is about! My want's was an incremental/differential backup tool which activates on a change to a directory and does the business. And did I mention is Free....
And here we go! Veeam host a raft of VM/hyperV enterprise tools but offer a free version of a backup tool that does exactly what I want eg , backup at a detected change and allow per file recovery! Just follow the site links to its free tools range and profit!
Much Love K.
