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.
It is very easy to use with NFS. Creating new volumes and mounting to servers such as ESXi or Linux is a breeze. It does also support CIFS but it is far less intuitive and requires much more effort. Replicated data is also very simple and robust in the form of SnapVaults or SnapMirrors. This data is either immediately or periodically replicated to a peer FAS in the cluster for retention.
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.
It does have a really nice and easy to use web interface to do pretty much anything you need with it. It was very simple to configure our volumes and luns and connect them to our VMWare environment using the interface. It has options to rename, shrink, grow, and other things with our luns and volumes. It was nice and easy to read graphs to see where you stand on your storage usage at a glance.
NetApp support in Brazil is managed by its partners. We know in other countries, such as the US and NO, they have support directly from Netapp. We have a very good NetApp partner working with us since the beginning, on both the implementation and daily support. Very few cases needed to be escalated to NetApp support, most of the cases are handled and satisfyingly closed by the partner.
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.
NetApp stacked nicely and gave enterprise-level usability for snapshot-based backups. Our previous RPO was several hours. It was selected prior to me arriving at the company, but It was selected for the hardware refreshes due to its compatibility with several other vendors, like CommVault and VMware.
