I like that this software is easy to use as well has helpful tutorials for beginners or advanced users alike.
In addition there are many features available which can be tailored according to your needs (e.g., file size limits). The only downside might actually relate more with my own personal experience than anything else but since we have been using oDrive for some time now; our data retention period was increased from 30 days up until 2 years without any issues at hand. This means you will get access to files much longer after they were originally created/uploaded.
