For the business public, solutions like One Drive may seem somewhat complex and solutions such as Dropbox or Google Drive may be too basic. Cubby gives you that balance sought by small and medium enterprises.
SpiderOak is well suited for local backups of the computer the client resides on. It is well suited for local area storage backups. It is less suited for remote backups, over a VPN or wide area where the data is continually changing. For data that continually changes, like in our document management system, the client needs to be on the same network as the data.
Since we are already a LogMeIn Rescue customer we are a fan of their products. We really do not see a lot that Cubby does not do for us that we need to do.
It would be nice to have a built-in password manager/keeper to share using the Cubby cloud storage. Users can share files in a secure manner, so why not be able to share passwords with them securely as well.
While I gave them a 7, it is in regards to the access to support. This is a business application and not being able to call them can sometimes be a problem especially when you need immediate support. They still tend to manage their support on a consumer line model and not a business grade model. With that said, I will say they are very knowledgeable of the product and how to resolve most any issue when I contact them.
I think Cubby is very comparable with all the others such as Drop Box, OneDrive, Box, and Google Drive. They all do similar things. But, I am not aware that the others will let you secure a document that is particularly sensitive in nature
In regards to overall performance SpiderOak is not as customizable as Unitrends, but based on the annual cost for SpiderOak and how we use the product, for a "Backup" to our primary backup solution, it is a welcomed option to our backup strategy when you consider the versioning, zero knowledge, share features and unlimited data.
