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.
As one of the best YouTube video downloaders on the market, Jihosoft 4K Video Downloader supports downloading videos from almost all video streaming sites (such as YouTube, Facebook, Twitter, Instagram, Vimeo, Dailymotion, etc.). What sets it apart from online websites is that it allows you to download entire YouTube channels & playlists and save them in HD, 2K, or even 4K quality. In addition, it has a one-click download mode that can apply your settings or preferences to all downloads, which will greatly save your time and energy.
Backup software: We run each program through the various types of backups it’s capable of. This is largely to test reliability and hardware compatibility, but we time two: an approximately 115GB system image (two partitions), and a roughly 50GB image created from a set of smaller files and folders. We then mount the images and test their integrity via the program’s restore functions. We also test the USB boot drives created by the programs.
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.
There are a few common practices for configuring when backups occur. The most common option is on a fixed schedule, such as once a day, week, or month. The second, which we prefer, is to upload file changes whenever they're changed and saved, otherwise known as a continuous backup setting. Services only transfer the modified part of the file in this scenario, so as not to overburden your internet connection or take up unnecessary storage. A third way is simply to upload files manually. Some may appreciate this degree of control, but this method is only effective if you remember to regularly run the backup.
