Backup and Disaster Recovery
The Technology At Work To Keep Your Systems Working
The NAS device can be configured to backup multiple Windows 2000 and Windows 2003 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. There is generally a three-week turnaround time
required for this base image transfer to occur. 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 NAS 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 NAS 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
NAS devices can be placed on a LAN. Each NAS device, depending on the
model, can be configured to backup one single server or multiple
servers.
Everything comes together in
our NAS 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.
