This is the process of backing up all of your important files locally on devices such as external harddrives, CD’s, or flash drives.
All of these types of storage are very portable. You can take it with you if you ever move or travel.
The files are also easily retrievable. All you have to do is plug it in and run the backup program. This makes the process quick and easy.
Local backup is much more vulnerable to events like fires and floods. Most people that choose local backups instead of remote store their files close to their original computer. If a disaster occurred, it is likely that both sources would be lost.
It is also possible to lose the backup files. It is very easy to store something and then forget where it was stored.
It is also a concern that older sources of data backup can become obsolete with advances in technology. It could cause problems if your data was stored on a certain device that stopped being supported by future computers.
Also frequently known as cloud backup, this is the process of storing and retrieving files at a separate site.
This type of data backup is much more secure than storing at home. It is not susceptible to the unforeseen events like fires or floods like with local. Whatever happens at your workplace, your files will be secure.
Remote backup also ensure security by encrypting your flies, usually with 128-448 bit encryption. So even if you are sending your files over an unsecured network, you can ensure that your files will stay secure.
Most data backup providers also keep a list of version of your files, in case you ever need an older version.
The main concern about remote backup is the transfer speed. Even if the files are being sent over a high-speed connection, things like upload limitations set by internet providers or firewalls can slow the speed considerably.
Another concern is that the business that stores your information could go out of business or be bought by another company. During this time, there is potential that access to your information could be more difficult.
