One of the best uses for cloud storage is offsite backups. I don't mean file syncing but real backups you can use to restore entire systems or applications. CrashPlan has, until now, offered some solid options for home and SMB users, But CrashPlan's owner, Code42, has announced that CrashPlan for Home will shut down on 23 October 2017.
While the Home plan was all about the consumer market, I dare say there were more than a few home-based businesses who took advantage of that plan. Instead, Code42 is directing people to their CrashPlan for Small Business plan or to their partner, Carbonite.
Carbonite is the go to option for consumers. CrashPlan for Home users, who are no longer core business for Code42, will have access to special pricing plans if they choose to transition to Carbonite.
Cloud backups make a lot of sense. If you follow the 3-2-1-0 backup mantra (three copies on at least two different media with one offsite and zero errors) they're a great option, as long as you disconnect or disable the backup system between cycles. There are some ransomware variants that actively seek out connected backups and encrypt those before attacking your main system.
There are a number of other alternatives if Carbonite's plans don't suit. Acronis True Image, SugarSync and Backblaze are popular and worth a look.
