Protected Volume Files (The Ultimate Backup Protection); Why You Should Make Regular Backups With Safe & Sound - McAfee STUDENT SURVIVAL KIT 1.0-GETTING STARTED Getting Started

Valuable and vulnerable disk organizational structure information is also
stored in various places on a hard drive. This includes the boot sector, partition
tables, directories, the FAT (file allocation table), and other structural
components. These structural components are used by Windows to find data
on the drive, organize it, and so on. If any one of these components is damaged
or destroyed, you will not be able to access the data you've stored on the drive.
The FAT, your drive's roadmap, points to the locations where your files are
physically stored on the drive. Files can either be stored in contiguous
locations or scattered in pieces in different places. Since files are not always
stored contiguously, the FAT information becomes even more indispensable
than if files were stored one after another, end to end. If a drive's file allocation
table becomes corrupt or scrambled (such as may be caused by a virus), your
computer will be unable to find and assemble all the pieces of your files. This
is true even if all the files' data still exists.

Protected Volume Files (The Ultimate Backup Protection)

Safe & Sound lets you create backup sets in protected volume files, which is
the safest and preferred type of backup. A protected volume file is a sectioned-off
area of the drive, sometimes called a logical drive. Safe & Sound's protected
volume files have some very special characteristics that let Safe & Sound
reconstruct backup files sector by sector, even if the drive's standard FAT is
damaged or completely lost. In fact, files can be largely reconstructed even if
large parts of the drive are unreadable or erased.
The protected volume file also includes enough information in each directory
entry to completely reconstruct a file's entire directory tree even if all its parent
nodes are erased.
Safe & Sound provides internal redundancy in the protected volume file
backups you create. It does this by marking each sector of each file that it backs
up with identifying information about the sector's contents and the file that
sector belongs to. Each sector in a protected volume file contains enough
information to allow files to be reconstructed from their individual sectors.
Why You Should Make Regular Backups With Safe & Sound
Your data is very valuable and costly to recreate. This means that making
frequent or even mirror backup copies of the important data on your drives is
crucial. A mirror backup copy is always identical to the original information on
the source drive.
