Why should a USB drive fail before the internal drive?
I went through 4 of them in less than two years.
My first one was Buslink, lack of cooling froze the drive.
Forgot the name of the second, it also went.
Then I bought ADS USB to IDE box, put a Western Digital
in it, few months and it also froze.
Then I bought Belkin USB to IDE box with a fan in it, and
a new Western Digital, for some reason it was very slow.
So I dumped them all put a slave hard drive in the computer,
its way faster, my large backups are handled faster.
In addition I have a drive that I mirror to.
The principle of a robust backup requires that the backup
medium is kept in a different physical location from the
normal medium. How does your solution meet this
requirement,
What they mean by that, is backup:
- To a storage website in the internet.
- To a media (Tape, CD/DVD) and take home daily.
- To a computer in a WAN.
- To a fire proof box.
You need one copy in the same physical place to retrieve
files that may have deleted or altered by my mistake.
I know an accounting small firm, that backup locally
to a backup computer, to the Internet, and take home
a DVD daily.
If the PC gets stolen, goes up in flames, suffers
electrical damage or a meltdown of Windows then your
internal backup drive will be history too.
So will the USB, except if the power supply went bad
then it could burn both hard drives.
Not only you need different ways to backup, you also
need different software.
For example, maybe the mirroring software failed
that night, then you don't have backup at all. Because
mirroring software wipe out the backup drive before
mirroring.
In addition to mirroring I use data backups, it
backups my important data.

With this program, I have extra methods of backups,
and I can retrieve files from it easily.
It does rotary backups, I backup locally, to a network
computer, then copy the backups to a DVD and put them
in a fire proof safe.

CD/DVD when done writing to see if all went OK.
Never enough backups, specially if got hit by fire, flood or theft.
