Protecting Local Disks
Even if most of your data is stored and protected on your storage system, your operating system files,
applications, and many other files still reside on each individual computer in your network. If one of those
local disks fails, it can take many hours to re-install and reconfigure the operating system and applications
on a new or repaired hard disk, and some files might be completely lost.
DiskSafe Express is a software application designed to address this issue. On each computer where it is
installed, DiskSafe Express provides reliable data protection and rapid data recovery in the event of a
system crash or disk failure.
DiskSafe Express protects Windows desktops and laptops by backing up their local disks or partitions to
the storage system. To make sure that you have recent copies of your local disk, DiskSafe Express can
automatically perform a backup at regularly scheduled intervals—either once a day or once a week,
whichever you prefer. (You can also disable automatic backups and just perform backups manually at a
time of your choosing.) Up to four backups are saved on the storage system. Once the maximum of
supported backups are saved on the storage system, the oldest backup is automatically deleted upon
every subsequent backup.
To ensure that valuable storage space isn’t used up by duplicate data, when DiskSafe Express performs
each subsequent backup, it copies only the data that has changed since the last time a backup was
performed. This also minimizes the impact on your network.Through unique technology on the storage
system, each backup is a complete point-in-time image. You can view or recover the entire disk or partition
exactly as it existed at a particular date and time.
Whenever you need to recover data from the storage system, you can do so quickly and easily. If you need
to recover just a few folders or files, you can access the desired backup and copy what you need back to
your local disk. If the protected disk isn’t your system disk (that is, the disk that contains the Windows
operating system files that the computer uses when it runs), and you need to recover the whole disk, you
can do so using DiskSafe Express. And if the protected disk is your system disk, and you need to recover
the whole disk, you can do so using the recovery CD. (Alternatively, if your computer does not support the
recovery CD but does support the PXE protocol, you can boot your computer from a backup on the storage
system and recover your system disk.) Recovering the whole disk makes it contain exactly the same data
that it contained at the time the backup was performed—you do not need to reinstall or reconfigure the
