The system itself allows you to add any feature.

The only bad thing is that this maybe depends on FreeBSD, and sometimes finding documentation is difficult.

For example, we knew that previous versions automatically enabled the Linux kernel, yet with the recent version, this was no longer the case. Now, there was the possibility of being able to create Debian-based jails, and finding the documentation was not easy or fast. That said, in the end, we succeeded.

If you find the documentation, it is always incomplete and fragmented.

They should include clustering for the solution. Presently, we cannot sync the setup with hyper devices.

The support for S3 needs to be improved.

The default settings for taking snapshots are not wisely-set.

The one thing that I find difficult to do which is very time-consuming is that I like to have a backup of the important files. However, they're so big. I haven't really found documentation that explains how to back up quickly well enough. I want to know: how I can connect a hard drive directly to FreeNAS, and then basically copy one of the shares, either a Window share or Linux share, to that hard drive. To do it over the local area network is very slow and very often, due to the fact that it takes so long, things will get interrupted. Either the router will reset or something will happen, and then it gets confusing as to how to get it restarted and get it going again once the connections are re-established. Therefore, being able to do a direct backup of the shares to an external hard drive is something that I would like. Or, if it could be done easily and more quickly over the internet, I'd like to find the documentation that would tell me how to do that. So far, I haven't really found anything that has worked that well.

One of my hard drives has failed and the documentation that I've been able to find has not helped. I know I've replaced drives before, however, I haven't been able to find the right documentation to get it done this time, and now I'm sitting here with a degraded system. I can still lose one more drive and not lose any data, however, I don't like sitting like that. I've got a brand new drive in there, and yet I haven't been able to replace the faulty one that is now in the recycling bin somewhere. That's why I need some documentation for backing up to just an ordinary hard drive. Right now I just find the documentation that is available lacking or confusing.

Scaling the solution is expensive.

FreeNAS should be better prepared for clustering.

Make it easier to find out how to fix things when something goes wrong. There is pretty good documentation, but sometimes it is difficult to find the right solution. When a hard drive has failed, it usually takes me quite a while to find out how to replace it. Since it is usually a very long time between occurrences, when it does happen, I have forgotten how to do it, and where I found the answers last time.  

Since there is so much storage, backing it up to another drive (e.g. before doing a major upgrade) over the LAN takes a VERY long time.

Its support for Hyper-V clusters.

They can improve the integration with PSA systems. This functionality could be better.

The latest version of the dashboard doesn't work as good as the previous version. Sometimes we change our dashboard back to the previous version because the latest version just doesn't work as good. This is a problem - especially if we want to make integration changes.
