A comprehensive data backup strategy is vital to your data security. Too many people wait until disaster strikes before they think about a backup. A good backup is an excellent way to protect against viruses, deteriorating hard drives, disasters and human errors. If it would not be cost effective or even possible to re-enter data, then you need a backup strategy.
Don't simply rely on backup software to get it right 100% of the time, no matter how good you think your backup software is. To ensure that your backups are protecting you, periodically test the backup jobs by attempting to restore them to an alternate location. This will bring out any flaws or corrupt data before it is too late.
Also, most backup applications also have a "backup log" or generate a "backup report" that can quickly identify any problems or skipped files in the backup job. Be sure to review these logs every time your backups complete for anything suspicious.
Many people think a backup is simply moving their photos, videos, music, financial documents, or other important files off to an external hard drive or removable disk. However, simply moving data from one location to another isn't giving you any extra protection in case disaster strikes. If there aren't at least two separate copies of your data, it isn't a backup at all.
However, even though a single backup may be a good start (two copies of your irreplaceable files), there is still some risk for data loss, especially if both copies are kept in the same location. (Think about things such as fires, theft, floods – if any one of these happened, they could easily damage or destroy both copies of your data.)
For the best protection against data loss, especially from catastrophic events, having at least three copies of your data (the original files, an easily-accessible backup, and a protected copy of your backup) is recommended. While some large companies may use dedicated off-site data storage services for this, you don't have to be a big company to have three copies of your data. Even something as simple as using an inexpensive online backup service to keep a 3rd copy of your data will be sufficient.
