I have been trialing and testing several cloud to cloud backup and sync solutions as of late. CloudHQ have come out tops in my opinion.

I started with multcloud and then tested cbackup but have now stuck with CloudHQ for several reasons. My journey started several months ago. I needed a rock solid reliable solution to backup ten google drives to an alternative location.

I found the other competitors appeared buggy and slow. For instance on both competitors they seemed to fail regularly and the error logs wouldn't show for one reason or another,
CloudHQ have neither of these issues, the logs are very informative and service seems to be very reliable and sync and backups finish successfully every time in my experience.
The backup and sync speed for CloudHQ is fast and reliable, the competitors I tried were a lot slower.
Another great feature is the cross platform resilience which is built in and also selectable. For instance google drive has several anomalies compared to other solution, IE you can have spaces at the end of file or folder names which with competitor solutions caused problems and error when syncing to alternate providers. cloudHQ renamed the files and folders for me so no issues arose which is a great feature not ideally  supported in the other solutions I tried.

I also found them reasonable priced for my requirements, if you need a backup or sync of less than 2 GB then you can get the service for FREE which is great for individuals or small business who have important data that require a reliable and resilient backup solution.

All in all I can recommend CloudHQ to anyone who need a cloud backup or sync. They have many other services they can provide, I suggest you take a look here and see for yourselves:
