The Key of Intelligent Computing - Virus Protection

By Veronica Carrillo

Almost everybody is using digital cameras or phone cameras to take photographs and create priceless digital photo memories. However, do you back-up? I wanted to outline some approaches for backing up digital photos and what to do if you were not able to back-up. Why back-up? From power surge, to user error, to a virus attack can wipe out your files. When it does happen, you do not want to lose years of precious photos. It is always better to be cautious rather than taking risks with digital photographs. Backing up your precious digital photographs can save you a lot of heartaches. Now that you agree that you need to back, what are the different back-up approaches? There are many and I have boiled them down to the top six approaches:

Save that Memory Card Simple to execute. When your digital photo memory card is full, just buy a new memory card and save the old one. With memory card prices declining, this approach is easy to execute. Remember to label the memory card and store it in a cool place where you can find the card. Be sure to have no magnetic device(s) near the memory card as magnetic devices can erase or corrupt the memory card. I would also recommend keeping an additional back-up of the memory card as memory cards are known to die from time to time.

Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table: "Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered." The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table.

Back-up on CD or DVD This is a very labor intensive approach. Also, if the CD or DVD gets scratched, you could lose all or most photographs on that storage device. Back-up on an External Hard Drive Increasingly people are dedicating an external hard drive for storing their digital photos or assigning a portion of their external hard drive for storing digital photos. Hard drives are getting cheaper and this could be a very good approach to storing digital photos.

Back-up at Back-up Site on the Web The value of this approach is that you can get to your photograph from anywhere. Also, as the web-site storage location would be a remote location from you computer or digital camera, you are protected from theft and other hazards such as fire. There are a number of back-up sites on the web for example Carbonite and Barracuda Networks. We have not done an analysis to recommend one but it should be easy to find such analysis. The draw backs to this approach are (a) you pay a recurring cost though solutions such as Carbonite start from $55 per year (b) downloading lost picture can take time and (c) you are dependent on a third party though this could be an asset (not a drawback) as the back-up provider can help to recover the photographs.

By taking regular backups and using the services of Advanced BKF Repair, you can be sure that your system will stay safe and secure for a long time. - 22787
