Will online backup services also backup a virus or spyware?
January 8th, 2009 - Posted by Joe
The following post in our Reader Question series is an actual user submitted question. To maintain the integrity of the original question, we do not edit or change reader questions in any way.
Q: My question about on-line backup is, if you somehow get a virus, or spyware, is this passed along w/ the regular backups and can they contaminate previous entries that make backups worthless?
A: This is an excellent question and one that we have seen come up very frequently. The short answer is- no, you will not contaminate previous backups if your computer is attacked by a virus or spyware. Here is the long answer:
Online backup services typically only backup files and program data and not the associated programs. For example, online backup services like Carbonite and Mozy will backup your Microsoft Office documents and settings, but not the actual Microsoft programs. So, spyware and virus programs will not be backed up by most online backup services.
It is possible that a document that you backup could include a virus, but viruses in documents are typically only activated when the file is opened. This is where having an Internet security software program, including anti-virus protection, on your computer is important. Most security software programs will scan files as you open them and alert you to any potential threats.
If your computer does become contaminated by a virus, we recommend following these steps provided by Len from Carbonite's customer support team:
When recovering from a virus infection, my recommendation would be to reinstall your operating system and applications, and in particular a good anti-virus program. Be sure to get the latest virus definition files from the manufacturer of the anti-virus program. (This is usually included as part of your subscription, and the latest definition files can be downloaded via the Internet.) After reinstalling your operating system and anti-virus program, restore your backup, but be careful not to open your restored documents until after scanning them for viruses.

If I backup a large amount of data (maybe even say my boot drive) and I find I need one small file from that backup can I go into the backup and locate that file and just down load it?

I am a Carbonite customer. I've never had to use it to restore anything. I'm also backing up my hard drive on a seperate hard drive. I've loaded a "virgin" OS with all the programs I'm likely to use, plus my documents, then made sure they functioned. this way, If something crashes, I have a "pristine" system (with all my programs loaded and configured)with which to start my Carbinite restore. What I'm wondering is, is there an online service that does this? After all, the whole point of a backup solution is to minimize the time and aggravation of recreating lost data. The only other solution that comes to mind is some sort of Slipstreaming of the OS to include the installation of my programs, and I'd still need a backup of my documents. Help me out here. Any suggestions?

I've learned some important things through your post. I might also like to say that there will be a situation that you will obtain a loan and don't need a co-signer such as a Fed Student Support Loan. But if you are getting financing through a conventional bank or investment company then you need to be able to have a co-signer ready to enable you to. The lenders will base their own decision on a few issues but the biggest will be your credit standing. There are some loan companies that will also look at your job history and make a decision based on this but in almost all cases it will hinge on your rating.

I'm really inspired with your writing skills as neatly as with the structure to your weblog. Is that this a paid theme or did you customize it your self? Either way stay up the nice quality writing, it is uncommon to see a nice weblog like this one nowadays..
