Memory cards reliable enough?

But I get the impression that nowadays memory cards are very reliable, so you could in principle put a 256GB memory card into the camera, and only use that for an entire trip. Any thoughts about this? I don't recall them being considered unreliable. Indeed we all cried the chorus of better to get solid state memory than the small spinning mass disks that were cheaper (and far as I can tell no longer marketed). There are all sorts of stories of lost cameras found years later with all the data intact. Indeed a recent camera was fished out of a lake 6 years after it was lost and all the photos were retrieved and the owner eventually located. http://www.cbc.ca/news/canada/manito...ipeg-1.3136501 Then there was this one. http://www.cnet.com/news/google-reunites-lost-waterlogged-camera-owner/ That said, any electronics can fail. I bring a laptop and offload images to the laptop as I go. There are other solutions as well that include data tanks and uploading images to a "cloud" account on the fly. You can even operate your own 'cloud' drive at home and send the images there. The trouble of course, on the road, is getting sufficiently high bandwidth connections to the net. In some places it's hard to get something that can reliably and quickly take off the 5 - 10 GB+ of images one can easily shoot in a day. This has been my travel fail safe redundant storage. It does full and incremental backups. http://www.hypershop.com/HyperDrive/HDU2-000.html -- Regards, Savageduck |

BTW: I find it best to format in the camera, perhaps that's what you do as well? I upload to Lightroom, note that the images have all been uploaded, and then close Lightroom. Lightroom backs-up when closed because it it set to back-up each time it's closed. You are living with a bit of false security there Tony, the Lightroom backup catalog does not back up the image files. The Lightroom backup catalog does not actually contain your photos, they must be backed up separately. Backing up your Lightroom catalog file is extremely important, it contains all the details about edits, keywords, and ratings you have applied to photos. Editing photos in Lightroom is nondestructive, which means Lightroom never changes the original photos. Instead, Lightroom records the details of your edits in a catalog file. The Lightroom catalog file also includes the location of each photo on your computer, as well as metadata for the photo, such as keywords and ratings. You should develop an additional backup protocol for Lightroom. There are two ways to deal with that if you have an external HDD. Starting with import you can imort to two locations, you working location on your primary drive, and to the secondary external archive/backup drive. The other way is to conduct a regular back up of your primary Lightroom image folder & the Lightroom catalog folder to an external HDD. The card is re-placed in the camera and then formatted in the camera. If there was some really important images involved I might take an extra step to back them up another way, but I'm talking about my normal procedure here. Images are uploaded to a file on D:, and the D: drive is backed up to an external drive every night. That is a good back up plan for your originals. However, by copying the Lightroom catalog folder to the same external drive you also have a backup of all the ratings, keywords, edits, etc. -- Regards, Savageduck |

Images are uploaded to a file on D:, and the D: drive is backed up to an external drive every night. leaving you vulnerable for as much as 23 hours. |

Lightroom backs-up when closed because it it set to back-up each time it's closed. do you have it set to copy that 'backup' to a different drive not in the computer? Remember, that is only the LR backup catalog, for adjustments, edits, and metadata, not an image file backup. if not, then it's not a backup. it's just wasting time and space on your drive. The LR backup catalog file is like an OSX recovery partition, and does not take up much space, but it should also be part of a backup/archive plan. It is usually zipped and depending on your LR content somewhere between 50-300MB. more importantly, lightroom does not back up the photos, which is the important part. the catalog can be recreated but the photos almost always cannot. Exactly, hence a seperate backup of actual image files should be maintained, or you have no backup at all. Images are uploaded to a file on D:, and the D: drive is backed up to an external drive every night. leaving you vulnerable for as much as 23 hours. ....but there is still a backup of originals which is more than many folks ever do. -- Regards, Savageduck |

It is usually zipped and depending on your LR content somewhere between 50-300MB. it can take up a fair amount of space depending on previews and a good backup strategy would include the lightroom catalog anyway. it also takes time to do each time when quitting the app and if you don't quit the app it won't be done. more importantly, lightroom does not back up the photos, which is the important part. the catalog can be recreated but the photos almost always cannot.

After I download the images from my card to my computer I format the card. It seems that what you do is leave the images on the card and continue to shoot. I don't see any advantage to that. Am I missing something? Never had a problem with one but I copy the images to several different computers on a regular basis If redundancy is the goal, it's not necessary to retain the images on the card. They can be copied to other devices other ways. The card holds so many images I have no worry about it getting filled...I can format the card every six months if I want. I am thinking of just keeping them , when full for one more b/u though |

I use SanDisk and Lexar CF and SDHC cards and have not exerienced any failures. That said there was a period back when I was using 2 GB CF cards that some Lexar CF cards would only upload to my desktop using their proprietrary card reader, and their proprietry card reader would not read other brand cards. I am glad to say they fixed that thinking some time ago. I still have two of those readers which were bundled with the CF cards, today they are just useless relics. -- Regards, Savageduck |
