Why use external storage?
• Advantages of external storage
• External storage devices provide additional storage other than that available
in the computer.
• Data can be transported easily from one place to another.
• It is useful to store software and data that is not needed frequently.
• External storage also works as data back up.
• This back up may prove useful at times such as fire or theft because
important data is not lost.

My cloud or their cloud?
• What is the “Cloud”?
• A remotely located (not contained in the computer) hard drive or
hard drive group that is used to store electronic data such as
photos, videos, documents, etc. The drives may be in one location
or in several locations.
• The data may be accessed from any compatible device and from
any compatible location.
• There are two types of “Cloud”:
• (Their) Public Cloud Service, and;
• (My) Personal Cloud Storage.
My cloud or their cloud?

• Dropbox
• Flicker
• Google Cloud
• Icloud
• OneDrive
• RealPlayer Cloud

My cloud or their cloud?
• The choice is yours!
• Their Cloud:
• The service company provides the needed expertise.
• The service company manages the hard drives and the backups.
• Your data is stored along with other persons data on the same
drives.
• There is usually a free base amount of storage provided. Additional
space is available for a fee.
• Their cloud service is not physically located in your house so there
are no worries about theft or other unforseen happenings.
My cloud or their cloud?
• The choice is yours!
• My Cloud:
• Some computer savvy is needed.
• Only your data is stored in the system.
• You have total control over all aspects of the system.
• You select the hardware package(s).
• You are responsible for all system repairs and security.
• You configure the storage format (RAID) and other system formats.
• Your costs are essentially a one time expense.
• You choose the number/size of the drives.
Personal cloud setup
• Questions to ask!
• How much data storage do you need?
• 500 GB stores approximately 8,500 hours of music or 500 hours of
video or 155,000 photos or 250 hours of movies.
• What devices do you want to use to access your cloud?
• Make sure that the software will work with each of your devices.
(iPhone, Windows tablet, Android smartphone, etc.)
• Is the system and software compatible with your computer?
• Windows 8.1, Mac OS X, etc.
• Redundancy backup mode desired. (One or two drives or
more.)
Personal cloud setup
• Personal cloud products can cost from $150 to $300 for a 2TB drive.
• Although, the software for these solutions is intuitive, you definitely
need to have some computer knowledge to setup and maintain them
at home.
• If you want other family members or friends to have access to your
personal cloud, you’ll be responsible for setting up accounts for them.
Personal cloud setup
• The setup and running software and instructions are included with
the hardware package or are on-line.
• Once you select a personal cloud solution, you’ll need to install it on
your home network. These are the typical steps you’ll need to follow.
• 1. Take the NAS (Network Attached Storage) drive out of the box
and attach it to your router or a network node.
• 2. Power it up.
• 3. Open the included software on your computer. You’ll likely have
to run installation software first.
Personal cloud setup
• 4. Open the program and follow the prompts to pick an IP address. You
should also be able to name the drive and make a few other
customizations such as adjusting the power settings.
• 5. Next, identify which files you want to backup to the personal cloud.
This is a good time to choose how often you want your files backed up.
• 6. Create your login information. This is what you’ll use to access your
personal cloud from other devices.
• 7. Update your router to point external traffic looking for this resource
to your storage device. This is sometimes known as port forwarding.
This may not be necessary when using manufacturer’s own NAS portal.
Personal cloud setup
• 8. Login to your personal cloud from your smartphone or
tablet. (Note: Make sure there’s software or apps included that
will work with your devices.) Typically, your personal cloud
product will include remote-access software. This is what you’ll
use to login to your cloud from other devices.

manufacturer depending on the software used.
