This is all about the selling you a "Device" and prices vary greatly between resellers. The devices work well, but the pure cloud solutions need a lot of work.
We save a lot of money using QNAP for the backup of Virtual machines. We installed a QNAP in the datacenter of our Cloud Provider and the cost of the backup and storage that we use is, at least, 1/10 of the cost that we had in the past. We can choose what kind of drives we can install, so if we want affordable we can use 5400/7200 hard drives, if we need speed we can use SSD drives.
Quick solutions can be produced with flexible storage pools
It can create a powerful customizable system on its own, along with connectivity features and add-ons.

Advanced user management can be easily provided either in its own interface or on the domain.
It can take on the role you want with its integrated modes or add-ons that you can install later.
Most wonderful feature, advanced support service, we never had any unsolved problems and the support engineer was always interested, followed one to one
With web, ssh, ftp, winscp connections, you can easily access in any environment.
SQL Backups just don't work reliably. For us, we lost all of our SQL data backed up through the CTERA Application process. Although the logs indicated a success, that was really not the case. This came close to putting us out of business. Luckily I had taken a genuine SQL backup to a folder. Unfortunately it was a month old. We had to pick-up the pieces from there.
Don't use it for file sync and share. There are better products out there i.e. anchorworks.com
Support sucks. Good luck with response time and answers that are inconsistent between team members. For example I had to rebuild a VM from scratch. When I re-installed the CTERA client It obviously thought I was adding another device. When I inquired to tech support, one member said "copy the old Data folder" (I still had the old VHD. That did not work). The other directed me to the correct spot to just change the associated folder. The turn-around time was over 24 hours for this simple fix.
Documentation, plenty of fodder but no real tech there.
QNAP NAS is a really good product, but I think the best part is the support for the products. Whenever I have a question or imagine something that won't happen, I can ask the support side. When the support engineer understands what I want to do, he does his best.
Unfortunately CTERA does not stack up well if you want a pure cloud BDR. I have use iDrive and Asigra. iDrive has similar support and SQL backup issues. Asigra can vary widely in support and price, but the software is solid.
