Not sure if it's something I'd swear to, but out of everything I've tried, I still think is the best for me.

It's not perfect - I have my frustrations about it - but it's the most convenient and reliable service I've had especially for backing up local files and folders.

My job is in a hybrid setup so I have my work files in a portable SSD. I have some folders there that automatically back up to the cloud whenever I plug my SSD to my laptop at home. I also have folders in my laptop and hard drive that are backed up.

Backup (upload and download) stops when I shut down my PC, and automatically resumes on boot. And the upload and download speeds are fantastic.

The feature I love the most is Rewind. Basically you can go to any day and time within the past month and find all the files your cloud drive has on that day. You can then restore or download those files or folders.

This thing saved my dumb ass several times recently, when some important folders disappeared from my local storage. I went a day and time I thought I had the most recent version of the files and downloaded them back. And poof, problem gone.

Their is good, too. I'm on the monthly plan for 2Tb storage because that's the most reasonable for my needs. Compared to others I've tried, their pricing is the best for the storage capacity and features.

In terms of security, I think they have encryption features but for an additional cost. Haven't had security issues for my use case without it.

I'd warn you about their lifetime plans tho. I haven't tried it but I've read several bad reviews in their subreddit. Apparently pCloud can and will delete files or revoke your membership if you have pirated materials uploaded to a lifetime account. You can look up the pCloud sub for more good and bad user feedback.

I hope this helps!
