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.
Safe & Sound automates the back-up process, doing the time-consuming and
repetitive work for you. It lets you decide which types of files to back up, how
often to save them, and where you want the backup set located (on the same
drive, another local drive, or on a shared network drive). With Safe & Sound,
you can create mirror backup sets that are, at any given time, an exact replica
of the files you've selected to back up on the source drive. You can also specify
a short time delay in the backup, or back up manually by copying files to the
backup set on your drive if you prefer.
All forms of data storage are susceptible to losing the information they hold.
The most common types of data storage—hard drives, 3.5-inch disks, ZIP
disks or SyQuest tapes—are often called permanent storage (thus differentiating
them from the volatile storage in your computer's RAM, random access
memory). Permanent storage means the information remains intact even
when you turn off your computer. Permanent storage does not mean eternal
storage.
