NAS Technology

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.

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 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 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.

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.

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.

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.

When it comes time to restore the virtualized server back to physical hardware, our bare metal restore process allows restorations to dissimilar hardware.

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.
