Reliability: Generally speaking, data centers are backed up to the hilt. Some of the larger ones even back up to different geographical locations. Availability (hopefully 24/7) can also be important. Check for news of outages and the vendor’s own service blogs. If there are too many outages in service, buy accordingly. In truth, all the services we’re aware of are near-100-percent reliable.
In a recent allegation, YouTube, the biggest video-sharing platform, was accused of failing to follow the regulations prescribed by the act. They were found guilty and were forced to pay a settlement of 170 million dollars to the New York Attorney General and FTC for the violations. They were also asked to take measures in order to prevent further violations of the act. Thus, YouTube has asked for a revamping of its guidelines, demanding the YouTubers to tag their creations according to their targeted audience, which should later be approved.
Most services encrypt your files with strong systems such as AES 256 before sending them up to the servers over an encrypted connection. The majority of products we tested also offer a private encryption key option. If you choose to manage your own encryption keys (basically the "key" that decrypts your backup), know that it is your responsibility to remember it. The online backup service itself will not be able to help you reset the password if you forget it. On the flip side, this means that no one (including employees of the backup service and law enforcement officials) other than you can unlock your backups. This is ideal from a privacy and security standpoint. Use a password manager to keep track of your private encryption key if you think you will forget it.
