This keeps everything continually backed up in multiple locations. On my PC I'm using Zoolz (sadly they don't have a Mac client as yet) which uploads all of the contents from its local hard drive and then monitors for any changes that are copied over from the NAS. I have a job configured on my Windows PC that copies the images and LR catalog to the PC's local hard drive. With GoodSync I have two jobs always running on my Mac - one to copy my Lightroom catalog to my external HD, and another to copy the external HD to the NAS. It also works on Windows which is handy given I'm still using my old PC. I have now switched to GoodSync which offers more configurability and, crucially, much better feedback on any differences and actions performed. On Mac the easiest I've used is Carbon Copy Cloner. There are a number of software applications that can be used to keep each location up-to-date. Given external HDs are faster, it actually makes more sense to store the images on the external HD and backup that to the NAS rather than the other way around.Ī final advantage for using the external HD as my primary image store is that it's much smaller and lighter than my NAS, so I can take it with me if I need to. It's also worth considering that a NAS is like a little mini-server and can run other jobs or be accessed by other devices which will further slow down the NAS while it tries to juggle multiple jobs.Īnother consideration is that I still needed an external HD to backup the NAS images to. As the file size grows hard drive performance is a larger contributing factor in the time it takes to retrieve and render an image. I once tried to open a 1GB TIFF file (a 15 image stitch) from the NAS and it felt like it took minutes. With layered TIFFs that I've edited in Photoshop often being upwards of 100MB then things slow down a lot. Note also that article is talking about ~20MB RAW files from a Canon 5D Mark II. However in my own experience it definitely felt a good deal slower. The findings of this article show that the drive performance of the HD where the images are stored only has a small impact on the time it takes to load and render images. Surprisingly this shouldn't pose a significant performance problem for Lightroom. If I connect via wifi these numbers drop big time (half or less). Note these numbers are with the NAS connected via Gigabit ethernet (with a theoretical top speed of 125MB/s). So my external HD is twice as fast as my NAS and my internal drive is 3 times faster. Soon after I bought my NAS I became dissatisfied with its performance as access over the network was so much slower than the internal hard drives I was used to. Let me talk about some of the details of my set-up. If you had multiple users or computers needing access to files then this solution probably isn't for you. This is just for a single user using mostly a single machine.
