I have not investigated Carbonite's online backup competitors (Mozy, IDrive, Backblaze, Acronis Cloud Backup, etc.) to see how they compare regarding these issues.

I have not yet explored these issues in depth on Macintosh, nor with multiple computers, nor their business version, but I imagine that they are similar.

So, unless you (or someone you trust) spends the time to carefully review every data file and folder on your computer to see whether Carbonite is actually backing it up, you cannot be sure that it is doing your backup correctly. This might exclude a number of very important files on your computer from your backup, including Microsoft Outlook email database files, as well as data stored by less-common programs, which could render those programs useless if you ever restore your data from Carbonite. However, if you're currently using it (or if you are considering it for your backup needs), then you should know that it has the following potentially major problem: By default, Carbonite does not back up a number of less-common file types, nor many files stored in secondary folders, nor files larger than 4GB. It is very good at backing up common file types (documents, pictures, spreadsheets, etc.) stored in regular user folders (Desktop, Documents, Pictures, etc.). The Problem with Carbonite, a Popular Online Backup Service Summary Carbonite is a very popular service that provides online ("cloud") computer backup with unlimited storage for an annual subscription fee.
