"Choose a new home for your dropbox" - btrfs no longer supported

Checking with engineering on this.

Do you have Dropbox connected to any other devices using filesystems that Dropbox will no longer support? Wanting to make sure that the emaily you got is relating to your use of Dropbox on the ReadyNAS.

Are you using the in-built Dropbox function from the cloud tab or the 3rd party app from rnxtras.com ?

Obviously some users who are comfortable with SSH and have plenty of RAM could run a VM in VirtualBox but doing so would be unsupported. Hopefully there's a better way than that.

I can see that there's been a lot of feedback provided to Dropbox on their community: https://www.dropboxforum.com/t5/Syncing-and-uploads/Dropbox-client-warns-me-that-it-ll-stop-syncing-in-Nov-why/td-p/290058

We switched from using EXT4 in previous products to using the newer filesystem BTRFS. OS6 has always used BTRFS and we have no plans to change to a different filesystem. We released our first ReadyNAS OS6 systems over 5 years ago and the use of BTRFS has become more and more common on Linux machines in the years following.

BTRFS is superior to EXT4 in so many different ways. Features such as CoW (Copy-on-Write), Snapshots, Bit-rot protection, compression and more are very useful and important to many users and users that don't want to use those features don't have to.

We do let you use a range of other cloud providers from Amazon, Google, Microsoft etc.
