Technology
How It Works...
This new NAS-based technology performs at the block level where
the actual digital 1s and 0s are captured from the hard drive,
essentially eliminating failures related to open files. Because
block-level data is raw information that's independent of file
structure formatting, it's the most efficient way to write to a
disk.
The Technology At Work To Keep Your Systems Working
The DCSS device can be configured to backup multiple Windows
2000, Windows 2003, and Windows 2008 servers by partition or by
logical drives. There are no file or folder-level exclusions,
because a snapshot of the entire partition is taken at the block
level on the hard drive.
Also, database applications such as Microsoft SQL Server and
Microsoft Exchange Server transfer data in blocks without having to
worry if files are open or if they are in use.
Key Components Of The Device's Technology Are:
Base Image - The first backup taken
of a server is the base image, an exact copy of the currently used
space on the server. The base image is taken for each volume (or
partition) on the server. Once the base image is set all future
backups are incrementals.
Remote Storage and Base Remote Backup Image
Creation - Your data is stored (in encrypted form) in two
secure online data backup centers, located hundreds of miles apart
from each other. The BASE IMAGE will be sent via a SATA II drive to
the primary remote storage facility. Incremental back ups
will occur in the meantime and they will collapse into the base
image when the transfer is complete.
Incrementals - Incrementals take place
at the frequency that you schedule. If you select 24/7 backups at
15 minute incrementals 96 incremental files will be created each
day. If you selected one-hour incrementals, 24 incremental files
will be created each day.
Incremental Forever Methodology -
Incremental Forever Methodology differs from regular incrementals
in that only one full backup or base image is required. This
greatly reduces the time it takes to perform subsequent backups as
each incremental takes only seconds to complete.
Synthetic Incrementals - Incremental
files are collapsed into synthetic incrementals (basically one
larger incremental file). This is done to ensure chain integrity
and to speed up restorations. The fewer hops from the current
point-in-time back to the base image, the faster your restoration
will be.
Recovery Options - Recovering files
and folders is a simple process where the entire image is mounted
as a volume on the DCSS device. The encryption is needed. Files can
then be copied to the destination server over the network. We also
provide utilities enabling your engineers to restore files,
folders, Exchange mailboxes or messages and SQL tables and
databases.
Virtualization (Physical to Virtual) Standby
Server Functionality - The DCSS device can “virtualizeâ€
failed servers while keeping the system in the same state as it was
before the problem arose. No configurations are necessary. Once
virtualized, the NAS will resume the backup schedule that was in
effect before the failure.
Bare Metal Restore (Virtual to
Physical) - When it comes time to restore the virtualized
server back to physical hardware, our bare metal restore process
allows restorations to dissimilar hardware.
On-site and Off-site Solution with Multiple
Restore Points - Multiple DCSS devices can be placed on a
LAN. Each DCSS device, depending on the model, can be configured to
backup one single server or multiple servers.
Everything comes together in our DCSS device to produce
15-minute incremental snapshots that safely reside within the
device and are ready to be used to restore a file, a file folder,
an email, or a database all within five minutes.
