I used zoolz two week ago, i'm trying to upload a file 35GB in size for testing. It's two weeks since the first time upload, the progress was up to 50-60% sumtime, and breaking to 30-35% in 10th day. Now is about 45% during two weeks for upload. Do not ask me that network speed is OK or not. When I used Google for upload, 30G is spending about ~ < 1 hour only.
And remember that mediafire/mega or some other had better speed more than ten time. It's completely free.
something weird if you delete files from their website. I have tried to upload a folder again after deleting it from Zoolz web application; the folder won't upload and the application states that all files are already backed up..
I got a 1 TB instant + 1 TB cold storage licence, (very cheap lifetime lic via a deals website). The Zoolz client on a Mac can at present (v 220.127.116.11) not be used to upload files to Instant Storage, only to Cold Storage. For instant storage you need to use a web browser, and they only support Google Chrome and there you have an upload limit of 1,000 files. On balance I think that Zoolz is more geared to corporate usage with their BigMind product. Not sure the needs of home users are well addressed with what is called Zoolz Cloud Storage.
