1. External Hardrive - They are great for people who want to have instant access to everything they own on a different computer, and for those who just prefer to have their data on something more tangible. The cons are they can break, they can become outdated, lost, stolen and damaged. I generally do not recommend any of these products.
2. Cloud based - These are great for the average user. All your data is automatically synced, and can generally be easily accessed via internet. You can easily get stuck with a bad service and have to pay them a chunk of money every month for their services. When the time runs out, you have to pay all over again. Generally I would say that small cost is worth it in the long run.
3. Data Recovery service - Great for small businesses to large corporations. When the data you need to back up or recover is far too much and too important for a small do it yourself internet backup. Problems include being expensive and a step away from your control. Generally these costs also outweigh the benefits and are a must have for most businesses.
