Backing up with online storage
Many feel that today the safest and easiest way to store data today is through secure online storage services. It is virtually impossible to lose data when using online data storage services as most have multiple backups of your backups, meaning if one set fails there is usually several more backups. If you are interested in keeping your most important files safe and secure for both the short term and long term, online storage may be right for you. *anchor*
Some data found in various programs and software cannot be completely backed up and upon a system crash you may need to reinstall some or all software from scratch. Many software and productivity programs allow for back-ups and restore points to be made through their own administrative tools, to be restored at a later date.
You may also want to list all of the software, browser additions, and preferred settings on your computer for possible reinstall and reconfiguration later if necessary.
