DiskSafe Express can automatically perform a backup at regularly scheduled intervals – either
once a day or once a week. (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 for each computer; each time a new backup is performed, the oldest backup is
automatically deleted.
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. Yet 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 want 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 included with the freeStor 4020. Recovering the whole disk restores the
disk with exactly the same data that it contained at the time the backup was performed – you
don’t have to reinstall or reconfigure the operating system or applications.
