![]() This will change a couple of things, from the simplicity of the backup arrangement to the path the images take on the way from the card to the archive. Images take up a lot of room on your hard drive, and for many photographers, it's necessary to have a dedicated storage device just for your images. Even if you implement an additive backup system, you're likely to update or migrate the images from that drive eventually, and at that point you introduce the possibility of some kind of corruption.įigure 3 Once you add the write-once media to the system, you're fully protected.įigure 4 This movie outlines how the backups above can be configured. We suggest that this is an even better system for backup because the write-once media provides significant protections that are simply not available on hard-drive-only systems. If your offsite drive is set up to be an additive backup (link), then you're even more protected against some kind of file corruption or human error.įigure 2 The addition of a second drive fills lots of gaps in the simple mirror system. This provides excellent disaster recovery backup, as well as the ability to keep a rolling backup of current work. You can add a lot of protection to your image files by making an additional copy on a second external drive, and taking that copy offsite. If the drive lives offsite, then it provides better disaster recovery protection at the expense of protecting current work as frequently.įigure 1 shows a laptop mirrored to an external drive. Of course, this means it's also vulnerable to many of the same hazards of the primary - theft, fire, etc. If it's nearby, then it can be updated often, providing a rolling backup of current work. This arrangement has a few weak spots – either the backup drive lives near the computer or it lives offsite. It's not ideal, but it's infinitely better than having no backup at all. ![]() If you've only got one computer, and all your stuff can fit on a single internal drive, then you get a reasonable amount of protection by mirroring the primary drive to an external drive. Let's begin by looking at the simplest system and the most basic way to backup your digital data: a simple mirror or clone. One computer – single drive primary systems And the final system shows how to scale the tools to work for a client-server system. The third example shows how backup can be configured for a system that includes a laptop and a desktop workstation. In the second system, the data has outgrown the internal drive. In the first, all the data can fit on one single internal drive. The first two options each show a one-computer system. If you've read through the pages on Backup Overview and Backup Types, you'll see what the options are, and how you can create the best system for you. In reality, there are many different specific configurations you might use. Of course, this page presents a limited set of options. We suggest you start at the beginning, even if you know that your needs are more like the ending system. By adding the complexity one step at a time, it's easier to see what each element does. With Linux and ZFS, QuTS hero supports advanced data reduction technologies for further driving down costs and increasing reliablility of SSD (all-flash) storage.This page looks at backup configurations starting with a very simple one-computer system, up through a multiple client-server configuration. QuTS hero is the operating system for high-end and enterprise QNAP NAS models. WIth Linux and ext4, QTS enables reliable storage for everyone with versatile value-added features and apps, such as snapshots, Plex media servers, and easy access of your personal cloud.
