I once made a purchase of a lifetime plan from Zoolz with 1 Terabyte of storage. After about 3 years, I received a notification that they were no longer able to maintain that plan and if I wanted to continue with them, I would have to pay a monthly fee. I left them. I would never buy any of their storage plans because they do not honor their agreements. I have pCloud. I paid a reasonable amount of money for 500 gb of lifetime storage and I’ve had them longer than Zoolz and they honor their agreements. Watch cloud storage plans that offer large cloud storage for a very small amount. I had one with SkyLab which was a reseller of Zoolz and they went out of business. You don’t want to have your plan go up in smoke either because the company goes out of business or they fail to honor their agreements.
