Idrive also retains all deleted files forever which is an extra layer of security and beats Onedrive by a mile which permanently deletes recycled files after 30 days. I don't use the sync service as I have Onedrive but if you want to use just one cloud sync/backup service, Idrive has it all in one package. Idrive also has a sync function, which can operate like a cloud sync service like Onedrive. The next day I got a got a call from a human asking if everything was working well. When installing Idrive on a new computer I used the chat service to get some info. Onedrive only has email support which is usually nowhere as useful as having someone to troubleshoot with in the moment.

I've never had to wait more than a few minutes for help. Idrive has very robust phone and chat support. Also, a full restore of a crashed hard drive can take days to do online but probably less than an hour from a local backup. I have external hard drives connected to my two computers and having a physical backup is an extra layer of security that is important. One aspect of Idrive I like is that you can do both local and cloud backups.

For years I've used Onedrive but also use Idrive for extra security.
