This is true. If you have say 4 partitions on a drive and the drive fails. Those 4 partitions are lost and no way to retrieve the data short of a very expensive professional service. Even then no guarantee they will be able to get everything.
Separate hd for data is the most logical setup.
That way OS drive fails you only lose OS and programs. Backup Backup Backup
The most important step any user can do to safe guard their contents.
Personally I say once a week but this will depend on the amount of new data you have.
You may do it every night if needed.
What I would suggest you do is to Backup
your Data Files.
For this I would suggest using a External Hard Drive Enclosure.
This will allow you to keep your Important Data
safe and Separated
from the main system in case of problems. The cost for this kind of Backup System
has come down a lot. I would suggest a 500 Gig
capacity for your needs. Since you will only be Backing Up Data Files Only
this should be sufficient to do that for you. Follow the next two links to see examples of the price you will be looking at.
I suggest going to Microsofts Backup Tutorial
and follow the steps to do a Backup
to a External Drive
and also it will guide you on how to do a Scheduled Backup
even at night.
Another way you can do a Backup
is by using DVD’s.
This method is just as effective and can be done using the same steps as above.
