By strange behavior I mean that it was forcing itself into a disk rebuild as if a drive had failed. The rebuild was successful without replacing the drive, but it caused me think that I should upgrade my data storage solution sooner rather than later.
A Massive Amount of Images
Now I have a lot of images from a decade of digital photography. I have over 121,000 images. I organize by images into several folders based on my usage of images. I use Adobe Lightroom for my primary photo editing platform. After capturing an image I use Lightroom to bring it into my computer in an "Original" folder organized by date. I load all images in the DNG format. After bringing in the RAW files I select the images I am going to process further with Lightroom tools and then I use Lightroom's editing tools or I use Photoshop or other software to further process the images into my production photographs or art products that I print for exhibitions.
My original storage solution was a Drobo 4 bay unit with a USB 2.0 interface. It was configured with two 1.5 Terabyte Western Digital Green Drives and two 2 TB green drives. With a total storage capacity of 7 TB of storage Drobo's proprietary "BeyondRAID" architecture provided 4.53 TB of usable storage. An explanation of BeyondRAID can be found on Drobo.com:
"Drobo’s BeyondRAID technology solves the fundamental issues that traditional RAID can’t. Built on the foundation of traditional RAID, BeyondRAID adds a layer of virtualization that chooses the correct protection algorithm based on data availability needs at any given moment. Since the technology works at the block level, it can write blocks of data that alternate between RAID protection levels.
If you need to add storage capacity to a Drobo, simply insert additional disk drives or replace the smallest disks with larger ones – no need to change RAID levels, purchase a new storage array, or go through the complex administration of pooling RAID groups."
A more detailed technical explanation can be found Drobo's e-book " Drobo Technical Innovation" that I have made available on my Dropbox site at Drobo e-book on Dropbox.
My Old Backup PlanTo back up that amount of data I was making a full backup of all my critical folders utilizing Acronis True Image 2014. The backup files were stored on an Internal 2 Tb disk on my computer. As my photo collection grew I started experiencing more and more issues with storage space. I knew I would have to buy more disk. The other problem with this scheme is that I had only one backup set. If it was corrupted I didn't have any backup.
