I've used it as a cheap online backup in tandem with my physical server backup routine. Ive restored from it when I've had the odd accidental deletion from physical backups and not had any issues. Do I think it will be around forever? No. Is it a good interim service for none critical files alongside a physical backup routine. Absolutely.
Reminds me of the time when I signed up with an ISP called Red Hot Ant about 20 years ago. Paid something silly like £20 or £30 for lifetime access to an 0800 (or was it 0845?) dial up service. At the time many said that it was too good to be true and wouldn't last. They were right!
I am sure some people have a use case scenario for a 1TB cloud which is not end of the world if they go bankrupt tommorow and all data is lost. (this can happen). however most people looking online will not understand this and might put all there files here and nowhere else which can lead to bad things. if something sounds too good to be true it normally is. 1TB Google storage for 20 years would cost you 1600 quid. 30 quid sounds way too good to be true. would i trust my data with them hell no, would i use it for backing up movies or a duplicate of other cloud non confidentials files, yes
I think I am saying the same as Creatishh.... It is not apparent, how Zoolz, which appears a small company, would fund an ongoing cost for AWS storage, which incurs a monthly cost, from a one off fee. Hence you can't really be confident your data will still be available at the point you want to restore it, which defeats the object of a backup. I suspect 'lifetime' subscription refers to the lifetime of the product, not your lifetime. That has been the case with other lifetime subscriptions such as VPN. When the supplier gauges that money coming in does not cover the cost of ongoing subscriptions they can deem the lifetime of the product to be over, retaining the profit from previous subscriptions. I would feel more confident in a backup to a removeable device I owned and securely stored, or cloud storage provided by a big vendor such as Google/AWS/Microsoft.
