SmartVault sends out a cover letter with the tax returns that includes a link for them to download their tax returns, avoiding the insecurity of an email attachment. It does not include a statement retrieval feature but does work very nicely with a third-party app called FileThis. The majority of the users in the office have not been able to install the Outlook plug-in due to "a certificate error." In five years, SmartVault has not addressed this issue.
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.
Reaching someone is more difficult than it should be. Also, they don't take possession of known issues always suggesting it is a local PC issue in initial conversations. That, of course, can be frustrating for the end-user.
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.
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.
