“Dear Chenkun. What are some drawbacks of online backup? Could you please enlighten me about this? Thanks, Joanne S.”
One of the common drawbacks of online backup is speed. Especially during the initial backup, the total time to transfer all the files online will really depend on the amount of files and the speed of the internet.
In some cases, even if internet speed is fast, the large files may take up a longer amount of time than expected. Again, this is mostly evident during the initial backup stage. According to some backup specialists, one of the reasons behind this is because the initial backup process uses the bandwidth of your Internet connection. The initial backup process may take quite some time depending on how much data files you have on your computer. This may temporarily slow down your Internet connection, that is if you don not have a broadband connection. That is one of the reasons why online backup works more efficiently with a broadband connection.
Now once the initial backup is completed, maintenance backup becomes a lot more faster since only new files and changed files are backed up. This uses up less bandwidth. The back up process happens in the background, and you may not even notice it.
With an asynchronous Internet connection, the upload speed (from your computer to the Internet) is significantly lower than your download speed (from the Internet to your computer). If you use an asynchronous internet connection, backing up files may take longer.
The good news is that some online backup services are now trying to resolve this issue by proposing a rapid-start service.
Those very first online backups that are done could take months to move across the wire. That presents an opportunity for a lot of these companies to provide a rapid-start service, where they can go in with an appliance, back everything up for that initial first full backup, and then go back to their facilities, load it up, and from that point on, the backups are just doing incremental backups.
Another way to deal with this issue to set the system to automatic mode. This allows online backup of designated files to be done as long the computer is on and is connected to the internet.
Another common drawback is security. How secure are the files online? All the files transmitted online are definitely secured because they are encrypted before leaving the computer. This encryption process secures the data online. Companies such as Carbonite, which the market leader in the online backup industry, describes the encryption process in a more detailed manner.
According to this website, your files are encrypted with the highest level of encryption used by banks, which is 128-bit Blowfish encryption. The encrypted files are then transmitted to the company’s state-of-the-art data centers located in Boston using Secure Socket Layer (SSL) technology, again the same technology used in online banking and ecommerce transactions. That is how secure the files are transferred and stored.
It used to be that online backup software was expensive, making it not affordable to most people. However more recently, as more people are now using online backup, prices have become more affordable. Using promo offers such as Carbonite offer code for home use and Carbonite business offer code has made online backup software truly more affordable for people and businesses.
There are definitely some drawbacks with online backup and that is why it is important that you choose the right service to use. Like any kind of service, nothing is perfect. But one thing is for sure. These drawbacks are certainly manageable.
