I have the same issue. Running a Plex server (~6TB) at home, and thinking I need to put my media in a more accessible location. Are you using Amazon Drive as the one true source and syncing it locally to use with your Plex Server? Or are you pulling/streaming directly from ACD?
As I mentioned in another comment, you can avoid all that by using encfs, which encrypts the files before they ever reach amazon.
Edit: Just read the first reddit post. I call BS on anyone using encfs consistently and receiving a legitimate email from Amazon. Unless they've broken strong encryption, there's just no way.
Or they could just be using it as an excuse to get rid of high usage (non profitable) users. Encrypted files + you use a lot of storage and bandwidth = get kicked off.
My setup is a little convoluted. I've found that using the write mount really slows me down, so I use a unionfs mount with the writes going to the local hard drive, and the cloud drive being the primary read source. Given that it's unionfs though, anything that I haven't synced will be read from the hard drive.
So the order goes: Sonarr/CouchPotato -> Local Hard Drive -> Amazon Cloud Drive -> Plex. I stream directly off the cloud drive for any file older than an hour, as that's my upload interval.
nice. so you read from ACD, because you're mainly writing to local? Or is there another reason for NOT reading from local? also, does local completely mirror ACD, or have you found a way around that?
It doesn't mirror it at all. The local stuff is only a temporary holding place for it to sit until it gets uploaded to ACD, at which point it is unceremoniously deleted. I have >10TB on my cloud drive, but I'm using <10GB on my hard drive.
