    Incremental back ups to external hard drive and importing to new computer

    investigator1 Community Member

      I need some clarification on precisely how to back up additional pictures on a PC to an external hard drive to keep all the pictures in the same catalog and folder structure.I have exported my existing catalog (exporting the negative files and including the previews) to an EHD to a folder I have created called My lightroom Photos.Within this folder there are three sub-folders:(1)My Lightroom Photos previews.irdata, (2) My Lightroom Photos.lrcat LRCAT file and (3) Pictures (which contain copies of all the subject folders I have created on import-the original pictures being retained on the computer hard drive). When LR opens you have the option of backing up the alterations to pictures in an EHD (but not the pictures themselves).So if some alterations in the develop module are made,these are backed up as a fourth sub- folder on the EHD with the date recorded.However,if certain pictures are added to Lightroom following the earlier catalog export, how can these pictures together with the alterations be added to that same exported catalog with pictures added to various established folder names -eg France, Italy etc? LR is currently set to back up to the parent folder-My Lightroom Photos.

       

      Secondly, I believe that to import the catalog into LR on a second computer,all that is necessary is direct LR to open the last dated LRCAT file from My Lightroom Photos folder on the EHD.However,my last backed up "fourth" LR folder only imported two grayed out images with no previews visible.

       

      Any advice would be appreciated.

          Lightroom is not a tool to create backups of your photos, nor incremental backups of your photos. The capability doesn't exist.

           

          And while you can use "Export as Catalog" to create a backup, that wasn't the purpose of the command, and there is no way to do an incremental backup.

           

          So, I suggest you use an actual dedicated backup program to make your backups and incremental backups.

           

          If you want to import the catalog into LR on a 2nd computer that was created wtih File->Export as Catalog, you need to use File->Import From Catalog ... is that what you tried?

            On the subject of incremental back ups, this means that although you can add pictures to LR and back up the alterations at the start up menu,this resulting back up is divorced from the new pictures so I wonder how they are supposed to be reunited by LR if the computer internal hard drive is damaged. I would have thought that Adobe could have provided a seamless and easy way to perform this for such a critical function.

             

            Secondly, I want to maintain my existing folder structure with all the editing history when I import onto the new computer.If you try to import from the catalog, this does not import the pictures in the relevant folders.It simply mixes up all the pictures in a non-structured way.I have dragged and copied my created LR folder on the EHD to drive C on my new computer which now resides in my Pictures.However an attempt to drag and drop the folder into the listed drive C within LR is not possible.

              This doesn't sound correct, although I'm not entirely sure what you mean by "resulting back up is divorced from the new pictuers". If I understand you properly, then I would say this is incorrect.

              I believe it is the user's responsibility to restore the catalog file and backups from your backup location.

              While I have never done a File->Import from Catalog for this purpose, you could certainly move the entire existing folder structure to your new computer using the operating system. In fact, I wouldn't use File->Export from Catalog and then File->Import from Catalog to move everything from one computer to another computer. But when you do the File->Import from Catalog, you do get an option to indicate where the photos will be stored.

                I've created a Smart Collection of all photos edited since DD/MM/YY, where I amend the date in the selection criteria to the last time I backed the photos up to an external HD. I use this collection to 'Export as DNG' to my HD, and then amend the date in the collection to today. When I next decide to do an incremental backup, I select all the photos in this collection, and change the date when I've finished.

                  Backups- When I import pictures,I copy them into various folders on my internal hard drive appearing in LR under pictures but copy the original raw files to a master file folder on my external hard drive which contains the same folder names as on my internal hard drive.This caters for a problem if my computer drive fails and the originals are lost.When I start LR, I also set the backup to back up my external hard drive.This creates a new lrcat file on each occasion within My Lightroom pictures folder established on the EHD.However, this does not back up the pictures themselves so I exported the catalog to My Lightroom pictures folder.If my computer drive fails,how is the latest lrcat file on the EHD linked to the pictures for the two to be restored together in a new version of LR? (this is what I mean by the fact that they appear to be divorced).Further, If I now add more pictures to the various LR folders on the computer,these it seems cannot be added to the already exported catalog on the EHD. So,whilst I may be backing up alterations to these pictures,the pictures are not saved within the same single catalog on the EHD.

                   

                  Importing catalog-I find that if the catalog has been exported as above and then the import catalog function is used,the various folders are not listed and the whole folder structure disappears (except for collections which are listed) and all the pictures from all the folders are mixed up.There must be a way to maintain the folder structure by copying the folders.

                    I assume that what you really need is some form of keeping the photograph folders on your internal hard drive in sync with the folders on your external hard drive (the catalog itself can be backed up from within Lightroom). This downloadable little utility works for me when I want to keep my spreadsheets, letters, iTunes files ...etc... backed up;

                    http://www.goodsync.com/download/update

                    It's nothing to do with Lightroom. You first set up simple jobs within the utility, telling it which folders on your internal drive should be backed up to which folders on your external drive. It will then run, and copy to the ehd any items in the source folder that have changed since the last sync. Then, if your internal hard drive fails, you can copy these folders and catalogs from your ehd to the replacement hd, using the original folder structure.

                     

                    In Lightroom, the catalog is the main organisational tool, rather than the folder. I let LR decide on it's own folder structure, because I never refer to my RAW files outside of LR. Hope this helps.
