I had an online backup service that was really cheap and when it came to getting a file back they said they couldn’t find it because the software only keeps the file changes for 7 days. That was a disaster, we lost some valuable info. Mastermind keeps your file versions for years. I found out that you should keep the everyday changes to your files for a minimum of 90 days, and snapshots for 12 weeks, 12 months and 7 years. I feel much better paying a little more for a reliable service and the knowledge they gave us on the right way to do it. Thanks
