When it comes to data security, tight access control is critical. Consider the headlines for breaches in data security. Besides the obvious need to control access to a network, data located on laptops that are then stolen are the number 1 cause for data theft. This is especially relevant to backup data - the things businesses depend on to continue operating in the event of theft, accident, or other data compromise.
Regarding computer backup strategies, it goes without saying that any form of backup is better than none. When speaking with business owners and self-employed people, it is never a question of should it be done; the questions are what gets backed up, when, and how? There are 3 main methods of backing up a Windows computer, as shown below:
Local Media Backup - Backing up to a physically attached device
Cloud Backup - Monthly subscription service backing up your data to the internet
Private Cloud Backup - Backing up to network-attached storage (NAS)
Though they all have their merits, some options are certainly better than others for most. What is the best method of backup for a Windows computer? This question seems similar to the question "What is the best form of exercise?" While there may be any number of responses, it does depend a bit on the circumstance. To a person that does not exercise, any form of exercise done regularly is the best. To a person that exercises regularly, the time available, equipment cost, and risk of injury may be the factors that matter most.
Local Media Backup
Traditional backup involves copying data files to local media, such as a CD-ROM, DVD-ROM, external hard disk drive, or even tape backup devices. The methods for copying files to these media range from very manual means (copying a folder or folders to the external media) to highly automated methods. While local media can be the simplest in terms of setup and usage, backup applications vary in terms of configuration and ease of use. Typically, this form of backup requires scheduling or some form of procedure to carry out the backup process.
Advantages
Cost - hard disk drives continue dropping in price, and are purchased once Security - data that never leaves your possession is safe Performance - data stored locally is readily accessible and fast to transfer
Disadvantages
Management - storing, organizing, and locking up physical items is required
Durability - physical media are susceptible to damage by fire, dropping
Cloud Backup
Common offerings in cloud-based backup include Carbonite and Mozy. For a monthly subscription, an application running on your computer will copy data files from your computer, via Internet, to a facility with numerous hard disk drives. The security and privacy of your data are addressed by encrypting the data both during transfer over the Internet and as files stored in the facility.
Advantages
Convenience - files are copied over the Internet automatically Low upfront cost - billed monthly or annually Safety - offsite storage of data ensures disaster recovery options
Disadvantages
Performance - large amounts of data require significant time Cost - subscriptions for multiple computers add up Security - data encryption is good, but what if the company folds?
Private Cloud Backup
What if cloud backup and local media were blended in a manner yielding the best of both? Enter Private Cloud Backup. The concept is simple; place a storage device on your network and use software to back up your computer to that storage. Network Attached Storage (NAS) is readily available and allows you to place the NAS anywhere on your network, whether local or at a distance.
Properties
Cost - highest upfront cost (large drive for everyone with room to grow), but lowest long-term cost (no monthly fee and no drive purchase each time a new employee is hired) Security - data is out of sight but on-site (and therefore accessible) Performance - data stored locally is readily accessible and fast to transfer Management - storing, organizing, and locking up physical items is required, but only once for the entire department or office Durability - physical media are susceptible to damage by rare incidents like a fire, but with redundant (RAID) drive setup, and under watch in a secure location, NAS devices are much less susceptible to local phenomena like spilling coffee or being dropped or kicked
Overall, private cloud backup makes the most sense for many businesses. It requires some network familiarity, but is generally quite similar to simple local backup.
