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
“virtualize†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.
