| What is an
Online Backup Service? |
|
|
An Online Backup Service
is an Internet-based service that allows computer
users to routinely backup and recover their important
data using a secure and trusted server on the Internet.
If you use your computer to create and save valuable
data for business or personal reasons, you should
make some type of backup of your important data
to prevent a total loss in the event of any kind
of system failure or human error. Simple data backup
can be done by saving your data to multiple locations,
copying the data from its original location to removable
media, another hard drive, or another computers
hard drive on the network.
To make this task easier, specialized programs known
as Backup Software exist to aid users in regularly
making a backup copy of their data. Since some users
are not interested in managing the tasks necessary
for maintaining their own backups, a new breed of
backup software was created, known as Online Backup
Software. Online Backup software is designed to
routinely copy your important files to a private,
secure location on the Internet by securely transmitting
your data over your existing Internet connection. |
| |
| What files
should you select? |
|
|
| Since your
entire hard drive is likely to be much larger than
the amount of storage you have purchased on the
backup server, you should be selective in the files
that you choose for backup. In general, you can
avoid backing up any programs that you can reinstall
from a purchased CD, such as Microsoft Office (Word,
Excel, etc.). Why pay for storage for "stuff"
you can easily re-install? Try to focus your selection
on things like your "My Documents", "My
Pictures" or "My Music" folders and
data files of your important programs like accounting,
income tax, contact management, etc. Your online
backup software comes with predefined filters, which
allow you to automatically select categories of
files without knowing where all the files are located.
Check the online help for Filters to learn how they
can be used. |

| Do you have
a chart for Bandwidth Requirements? |
|
|
It's very difficult
to analyze those requirements because of all the
variables added by FastBIT. However, the basic formula
is pretty simple:
Take the expected size, in MB's, of the data you
might see in a day, divide it by the amount of seconds
in the day and divide that number by 8 to obtain
MB/Sec Bandwidth. This will result in the required
bandwidth (MB/Sec) needed to sustain 100% load throughout
the day.
Example: Let's say we have 500 users sending
us an average of 600MB per month (this is about
what we see at the NovaStor Online Center), then
the formula follows:
600MB * 500Users = 300000MB (300GB) / 30days (per
month) = 10000MB Per Day (10GB) / 86400seconds (1
day) = 115.74Kb/sec * 8 (to convert to MB/Sec) =
.93MB/Sec or about 61% of a full T1.
Of course, this assumes that you have full saturation
throughout the day, which isn't going to happen.
It typically gets a bit peaky around noonish and
around midnight, so to accommodate the mean, you
should probably have a 30% overhead, which in the
above case, would translate to just about a full
T1 (1.5MB/Sec). |
