Backup 14 Terabytes of data

How do you backup 14 terabytes of data?

A client of ours recently approached us for some guidance on how to backup all their data from numerous external HDD’s and data stored on the local computers. The obstacles we faced our 14 terabytes of data and increasing, data stored on different devices and computers and nothing is backed up.

On first inspection of the external HDD’s three of them were old Omega and Seagate that varied between 200 gigabytes to 500 gigabytes, these had been stored and not been used for at least three – four years, alarm bells start ring!!! So firstly we needed to establish if these worked and the data was not corrupt. Fortunately all of them worked and all data was safe, then we had to check the newer external HDD’s ranging from 1 Terabyte – 3 Terabytes again these all worked and although the data was stored all over the place with no order we proceeded to make our recommendation.

Of course with such large amounts of data storing it in the cloud was not an option because of expense and time, so the option we proposed is two NAS drive (Network Attached Storage) don’t get me wrong this option is going to be expensive to achieve with the hardware that is involved and work to set it up not to mention there needs to be two of everything.

We could have chosen two pre-built NAS already assembled with drives installed but we wanted a specific amount of storage with at least 32 terabytes and from what we have discovered not many companies offer this kind of configuration and if they were to modify the specification it would be double the price of our suggested configuration.

So down to the nitty gritty, we opted for the Synology DiskStation DS1813 with 8 drive bays, this would allow us to configure the DiskStation with 8 x 4 Terabytes = 32 Terabytes. We needed one large logical disk with fault tolerance per unit so we opted for a Raid 5 Configuration. This was not an easy decision as it takes a whopping 10 terabytes away from the original 32 terabytes leaving a logical disk of 229367 Gigabytes or just under 23 Terabytes.

So bearing in mind that it took nearly 5 years to accumulate 14 terabytes of data which will now be transferred to one of the NAS and with an additional 9 terabytes free space this should allow for further data to be added for at least three to four years.

So one NAS will be used to transfer all the data into one central location, for easy access to historical and current data and one NAS will be used to backup the data stored on the first one. With the NAS drives being able to be networked both units can be stored at different locations, which means we have now provided them with a means to recover lost and deleted data, fault tolerance on the hardware and a means of recovering data should one unit have a disaster.

For the software to manage the backups we will be using Symantec Backup Exec Small Business Edition, firstly it will backup over the network and secondly it will backup individual workstations and thirdly it will backup multiple locations, this is ideal for our purposes as there is no Server to speak at the location other than a basic domain server (SBS Essentials)
