I am sure many off us have suffered that sinking feeling of finding precious images missing from a hardrive or even the complete failure of a hardrive. With increasing amounts of images being taken, these days a good back up strategy is vital. Your own strategy is very dependent on how important your images are. If you make a living from photography, a multi layered approach would be best, if you are an enthusiast on a budget, then you may consider a less intensive back up regime.
Backing Up On a Shoot
If you are on a location shoot or have hired models or props, it is worth backing up during shooting. There are a couple of options here. Frstly there are number of manufacturers that produce portable back up devices, basically an external hardrive with a built in card reader and in most cases a preview screen. These are excellent if you will be shooting a lot of images and will be away from home for a while. If you use one of these in combination with plenty of memory cards, you can keep images on both, ensuring a double safety net on location.
The other main option is to take a laptop, with or without spare external drives. This will give you the option of editing on location and creating double backups but, conversely will add weight to your kit.
Backing Up At Home
Whether backing up a single shoot or an entire collection, it is important to have a good strategy in place at home.
Your main image catalogue should be on a fast internal or external drive connected to your main desktop computer, if using one. Make sure that the drive you are using has plenty of spare capacity for your collection to grow into. For external drives look for Firewire 800, USB 3 or Thunderbolt drives for the fastest speed possible. Your primary back up drive should be a mirror of your main image catalogue and should be backed up either daily, or whenever you add a shoot or manipulate images. This drive does not have to be as fast, as once the bulk of the catalogue is copied, you will only be writing additions and manipulations to it.
Using image management software such as Adobe Lightroom or Apple Aperture is highly recommended as they both have powerful back up facilities whilst other options include using specialist back up software, that allows you to either specify which folders to backup and at what time, or to clone entire drives.
As a failsafe it is worth having a secondary home based hardrive that you back up on a weekly or fortnightly basis and kept away from your main computer. For ultimate peace of mind, you can keep a third hard drive off site, in an alternate location, giving you protection from theft or fire.
Options Other Than Hard Drives
As well as internal and external hard drives, you can back up to DVD or Bluray. If you choose this option, make sure you choose archival quality disks and make sure they are stored in acid free archival quality cases or pouches. Storage should be in a cool and dark and damp free location. The best quality DVD’s are designed to keep data safe for up to 30 years, which is considerably longer than the expected lifespan of a hard drive.
Another growing option is storage in the Cloud. The prices of Cloud storage have dropped considerably in the last few years and this is worth considering as a secondary back up, although not a primary one. Things to consider here are upload and download speeds, how long will it take to back up your entire catalogue, ease of use and most importantly the reputation of the company. There is no point in uploading thousands of image only to find the company has gone bust after three months.
With the relatively inexpensive price of all storage these days, it is worth making multiple backups of your work, both onsite and if possible off site, via external hard drives or the Cloud. Another thing to consider is that, whilst backing up your images is important, it could be rendered useless if you do not back up your computer system drive as well. Failure of your computer’s drive could lead to the loss of all your imaging software making it impossible to access your image catalogue despite being backed up several times.
