Backing up catalog from inside of lightroom extremely slow (30 min)

I have a catalog that is just under 5gb, if I navigate to the folder where it is stored and copy paste it onto my backup drive it copies in under 2 min. However, if I chose to backup my catalog on exit from inside lightroom it takes over 30 minutes (not counting testing etc). Obviously I can backup my catalog manually, but it would be nice if the built in backup feature worked like it's supposed to.
I'm running win 7 64
lightroom 64 same probelm in 4.3 and 4.4
the catalog and lightroom are stored on a ssd drive
backing up to a NAS ( my typical transfer speeds are 60-80 MB/s)
Thanks for any thoughts
-Dan

I tried to the local ssd with only a small improvement. Like I said, if I navigate to the catalog manually and copy and paste it to the NAS it takes under 2 minutes... (80+ MB/s), but done through lightroom it just crawls.  Lightroom either has a bug, or it's doing something much more than just copying the catalog to the selected directory. I've tried it with and with out check and optimize.

A 5 GB Lr catalog is a hefty catalog. But 30 min seems a bit long even for that. I suspect that the NAS drive or its connection speed are slowing things down.Try this: Create a catalog backup from within Lr to an internal drive to check whether that will speed up the process.

  • Lightroom extremely slow

    I don't remember having this issue before but with lightroom 5.5, it sometimes takes 3-4 seconds between when i make an adjustment in the develop panel and seeing the result.  In addition, zooming in to 100% of a raw file is extreeemeellly slow.  It sometimes takes as much as 10 seconds.  Im on a pretty fast computer too
    Intel i5
    6 Gb RAM
    GeForce 630
    Huh seems to be gone but it was chugging a bit in the beginning.

  • Nested Win2012/HyperV inside VM workstation extremely slow, any solution?

        My desktop has AMD 8-core CPU (3.2GHz) and 32GB RAM, I installed Windows Server Datacenter 2012 onto VMWare workstation 10.0.4, I assigned 4 vCPU, 16GB RAM and 120GB HDD to this virtual server, in the "Virtual Machine Settings",
    Hardware---> Processors,  My "Preferred mode" is "Automatic", I also selected both "Virtualization Intel VT-x/EPT r AMD-V/RVI" and "virtualization CPU performance counters".
        the issue I have is the installation of any VMs are extremely slow, try to install windows XP Professional (I use old OS because they are relatively less bloated, it will take 2h to finish, and I tried Ubuntu 8.0 and Centos 4.8 (I know
    both are not supported by Microsodt due to competing relations), it will takes forever, so I gave up.  Also when I use anything related to HyperV, it is very sluggish.
       I am setting this in my home lab, and my server's Windows 2012 trial license expired, so I can only play with HyperV inside VMWare workstation.  I also installed ESXi 5.5 in a similar way, it works smooths without much hiccup.
       Any solutions?  thanks!

    Hi Sir,
    Hyper-v needs bare-metal installation .
    In your case , hyper-v wasn't  installed on a real hardware .

  • How can I Add a photo to a catalog from inside another catalog

    I have a number of large catalogs with a small subset of pictures that have been edited and printed. I'd like to be able to have just a catalog of printed images so i can easily find them, reprint them, edit them etc. but not move them from their original catalog or original location. Is there an easy way i can do this. I know i can export the image as a catalog and then import the images to another catalog. But that requires opening and closing 3 catalogs. Is there just an add file to catalog and then a list of my catalogs would show up?

    Hi Howie,
    I also would approach this topic by analyzing "why did you use multiple catalogs" in the past? What functionality exactly did you want to get with that?
    Then ask/search what other means/features could fulfill the same need. As some others in this post I am confident that there are sufficient.
    Sometimes I think the term "catalog" was not chosen very wisely over a term "database", because people might tend to think of paper catalogs of the analogous world. Then e.g. such a *catalog* per customer makes sense.
    Once you understand that 1 catalog defines the (convenient) boundaries of your pictures' universe you might choose a different approach...
    The term "database" might have scared away too may non-IT-savvy users for the taste of marketing department.
    Having more than 1 catalog only makes sense to me if you have more than 1 computer to look at your pictures' universe. Even then you should carefully decide which one is master and which one more or less for just looking at or special needs.

  • Copying files from an external HD extremely slow!

    Hi everybody.
    Thank’s to read this message.
    I’ve a MacBook Pro 13” (mid 2009) core2duo 2.26 Mhz whit 2GB ram and running Snow Leopard 10.6.2
    The system runs perfect until i try to copy something from an external drive, takes a lot of time to copy it, for example a 600 mb file takes almost 15 minutes, thats ridiculous, the problem is only when the info comes from an external drive and not from the machine to an external drive.
    I’ve tried whit tree different external HD and cables, whit four different USB flash memories, happened the same whit the SD slot and whit the CD drive, the size of the files or the content doesn’t matter is slow whit anything, I thought in the external drives format (FAT32 most of them) but happened the same whit the Time Machine disk whit HFS+ format, yesterday i copy a 4.5 GB folder whit videos and photos from time machine HD and took 4, yes 4 hours!!
    Is a serious problem because while is copying a file uses all the machine resources and i can’t do anything else until finish writing the file. Also i think is not an Snow Leopard problem, cause i tried to install Windows XP whit Bootcamp and in the part when the system copy files from the CD to the HDD happened the same, just took extremely lot of time and i had cancel it.
    I already reset the PRAM, repaired the hard disc and made a test whit the Hardware test tool in the Snow Leopard disc but can’t find something wrong.
    Well, thats the problem, any idea or comment is appreciate, thanks a lot

    Hi Eww, thanks a lot for your answer
    Thats a good idea, but why happens the same when i'm out of Snow Leopard, i mean installing windows xp goes very slow.
    I think should be something that controls the in and out information flow, but i don't know.
    Any other idea??

  • Adobe Reader XI is extremely slow (10 mins) opening a large SharePoint library (3000 docs)

    How can I speed up the opening of a SharePoint library in Adobe Reader XI using the Open from Online Account feature.  This is an onsite, locally hosted SharePoint instance (not SharePoint Online).  The library is approximately 3000 files, almost all PDFs of varying sizes.  While it is trying to open the library, the message "Enumerating <Library Name>" is displayed and it takes over 10 minutes for the library to finally open up to be able to choose or save a file.
    This maybe could be acceptable if it happened only the first time you accessed a sharepoint site or library, but this occurs every time, and makes the Open from Online Account feature useless because of the extremely long load times.  How can I fix this so that it opens instantly, as it should be doing?
    Interesting to note, if I just click Open, then type in the sharepoint site address into the filename area (and not use the Open from Online Account feature), the library opens and populates instantly.  But I need an easy way to be able to have users browse a SharePoint site to save PDFs that aren't already saved there.

    I do not think there is anything you can do to change this behavior on Reader's end. There may be a way to configure your Sharepoint Library to change this behavior. Since I am not familiar with Sharepoint, I will ask if you can set it up as a drive on your system? As to making Adobe aware of this behavior I would file a bug report:

  • Saving tiff from Raw file is very slow (10 min) CS6?

    MY OS is 10.7 and using CS 6, Raw 8.3.0 . I am having difficulty saving files from my RAW file, it is now taking up to 10 min just to do a simple save in photoshop. I have 32 GB of Ram and 2700GB on an internal scratch disk. The process of saving will stop at about 50% then stall and at about 8-10 min the file will save as a tiff. What is going on, this just started in the past week?
    I reinstalled all programs and OS and updated CS6

    I reinstalled all programs and OS and updated CS6
    Whenever I begin to experience a slow-down in my system (Mac OS) I launch "Activity Monitor" which shows me where all my CPU and RAM resources are being allocated and how much. This is where I will usually find the resource hog. There is probably an equivalent system utility for Windows OS.
    The next thing I would check (often alluded to by the resource allocation check above) is what programs are being automatically loaded at launch -- your Start-Up list. For a Mac this can be found in the User info. I believe Windows also has this list, maybe somewhere in the Control Panel.
    Next, I will do as R_Kelly suggests and replace my preferences files for both Photoshop and Bridge. I have a good copy of each file saved where I can reload it when necessary.
    Last I will do a diagnostic hardware test, available on Mac OS by accessing the recovery disk. Not sure about Windows, probably in System Accessories folder or in the Control Panel. Once I discovered I had a bad stick of RAM memory that was slowing things down and even causing Photoshop to crash. Also check to see if your Scratch Disk is clean and defragmented. I re-formated my Scratch Disk once and that cleared up a problem I was having with Photoshop.

  • TS1398 Extremely slow iPad Mini - on Wifi

    Í have a 40/40 Mbit internet connection. It works wonderfully on my iPhone 5 and windows laptop, but my new iPad mini/retina is so slow I give up searching on the internet and downloading apps it takes forever!!!!!!!!!!!!!!!!  What is the solution to this problem.
    My iPhone is almost 20 times faster on the WiFI

    Hi,
    I have the exact problem however it only happens at home WiFi (airport express) but not at office. I don't know what type of  WiFi AP they use at the office but definately not an Apple one.
    I've also tried streaming the same videos with my iPad 2 and It was also quite fast.
    Both the iPhone 5, iPad 2, iPhone 4 and Airport Express are using the latest firmwares.
    Did anyone found a way to resolve this?
    Thanks,

  • Possible causes for extremely slow (10 min.) startup?

    I just powered on this morning, after having been powered down and unplugged all night (8 hrs), and I got the gray apple screen for ten minutes before OSX loaded.  Not sure what was taking it so long to cycle through, but I'm wondering if this is normal operation after having been powered down?  If it's not normal operation, can you help me identify an issue that might need addressing?
    Prior to powering down last night, the computer had been on or sleeping continuously for the past two or three days.

    Thanks. I haven't tried rebooting yet to check the startup speed, but I did what you said and there were quite a few disk permissions that needed to be repaired (pasted below). Any idea how/why these disk permissions were altered?

  • Read from 16 GB Micro SD is Extremely Slow

    I have had a new Blackberry Tour 9630 equipped with v4.7.1.40 software and a 16 GB micro SD card.  Reading files from the card is extremely slow.  I first noticed this with video playback (extremely jerky and freezes) and actually replaced my first 9630 a few days after purchasing it. 
    I eventually gave up on video playback but now have very recently been using Media Manager to upload files (.jpgs) from the 16 GB micro SD card Media Card to my laptop.  The bottom line is it is taking 10-15 minutes to upload 13 .jpg's (total 6.7 MB) and is a major pain in the butt.
    Some of the trouble shooting steps I have taken:
    - moved same 13 files to main memory on Blackberry then uploaded to pc in 10 seconds
    - moved micro SD card to my son's Samsung phone - uploaded the 13 .jpg's from it to laptop in 10 seconds (so the memory card is good)
    - installed Desktop Manager and Media Manager on my desktop pc and connected blackberry to it - same poor upload behaviour from files on micro CD equipped on the 9630
    - checked on blackberry Doc ID: KB05461 at http://www.blackberry.com/btsc/search.do?cmd=displ​ayKC&docType=kc&externalId=KB05461&sliceId=1&docTy​... and it states: 
         BlackBerry Device Software version Media card size limit
         BlackBerry Device Software version 4.5.0.81 Up to 16 GB
         BlackBerry Device Software version 4.6.0 and later Up to 32 GB
    so I should be equipped with the proper software vintage.
    I am not sure what to do next and would appreciate any and all assistance/idea's etc.
    Thx,
    Gerry

    You can use a USB flash drive & the camera connection kit. First download the pics to your computer.
    Plug the USB flash drive into your computer & create a new folder titled DCIM. Then put your movie/photo files into the folder. The files must have a filename with exactly 8 characters long (no spaces) plus the file extension (i.e., my-movie.mov).
    Now plug the flash drive into the iPad using the camera connection kit. Open the Photos app, the movie/photo files should appear & you can import.

Bascially EVERYTHING has become sooo slow, delayed, lagging etc. I have tried ALL possible checks (extensions, add-ons, plug-ins, download history, cache, cookies) & viewed nearly ALL the FF help sites. Is this a sudden/recent bug?? It doesnt only happen with Facebook, but EVERY window I open!!

    I've personally not seen this behaviour since Firefox version 2. It however re-appeared for me in 3.6.6 and 3.6.7 (current) and it's bloody awful. Makes everything I do take 50% longer ..... great for efficiency in the modern world.
    This 3.6 branch is so riddle with flaws which seem never to be fixed. Each fix / update brings with it more problems ... worst of all I see version 4 is already in development but they cannot even get 3.6 right ??? WTF ????
    Mozilla must stop chasing version numbers as has become the trend in the software world. Fix an existing version to perfection then start working on a new branch of the product.

  • Lightroom 2.6 trial download - how to build a catalog from scratch.

    I have downloaded Lightroom 2.6 trial version and am trying to build a small catalog for it.  I don't need my whole Photoshop Elements 8 (PSE 8) catalog, but I would like to build a small catalog out of images in the My Pictures folder so that I can experiment with this software.  It recognizes the existence of my old PSE 6 catalog, but says it is corrupt and ask about building a new catalog. It will not recognize my PSE 8 catalog.  How do I go about bypassing this "catalog recognition step" and go right to that part of the software that will let me build a catalog from the images contained in various folders in the My Pictures main folder.  Unless I can get to the part where I can build a catalog to test out LR 2.6, then I am stuffed (as the Aussies would say) as far as testing this product.  Maybe I need to download the Lightroom 3 Beta and see if it will recognize my PSE 8 catalog.  Any suggestions, insight on how to resolve this dilemma are greatly appreciated.  Thanks.
    Regards,
    WesternGuy

    When I bring up LR, it asks me if I want to buy or try...so to speak, I check off <try> and the <Next> and <Back> buttons are immediately greyed out and the only thing I can do is click on <Finish> or <Cancel>.  If I click on <Finish>,  It tells me that "the Lightroom catalog named "catalog" cannot be opened because it is not valid. Would you like to select a different catalog".  The catalog is not registered as a valid catalog."  It tells me where this invalid catalog is and then I have a choice of buttons that ask me to "choose a different catalog" or another button that says "Exit".  If  I select "choose a different catalog, then it asks for a location and gives me a button that says "Create a new catalog", it then goes to the My Pictures folder inside a panel that has at the top "Create folder with New Catalog" and then I don't seem to be able to do anything it likes. I never get to a menu that gives me the "File/New Catalog" option.(???)
    Maybe I need to uninstall and reinstall LR2.6.

  • When importing from an old Lightroom 2 catalog into Lightroom 4 (also from Windows to Mac) I seem to have lost all the development history of my photos.  Is there any way to retain that?

    I finally managed to get through the process of moving files and catalog from Lightroom 2.7 on a PC to Lightroom 4 on my Mac.  I think I did it all correctly and all my file and previews and some tagging seems to be there.  Two things are lost
    1 - Most importantly, the development history on my files.  I can see the edited versions in the previews, but as soon as I click on it, I can see that I lose all the changes I had made before.  When I look at Development history, it just says "Imported on...."  I'd love to get this back.  That is a ton of processing work just lost because I switched computers.
    2 -  The collection names seem to have come over, but they are all empty.  This is also a lot of work lost, though not as important as #1
    Is there any recourse?

  • Lightroom 5 do not recognise catalog from external HDD

    I am using Lightroom 5 now. In the earlier version, I was able to create catalog & save them in external HDD. Similarly I could open any catalog from external HDD with the lrcat file extension.
    However, in the current version, it does not allow me to create catalog nor retrieve catalog from external HDD.
    This means that I have to either transfer all the raw files to the HDD from the external HDD and then create the catalog in the laptop. After finishing all the editing, then copy and transfer everything back to the external HDD.
    I cannot imagine if whenever I have to edit something, I have to keep doing transfer between the laptop HDD & external HDD.
    Any experts can advise?

    I am using LR 5.2 and I do not have this problem. My Raw files are on an external hard drive and my catalog together with its previews and Smart Previews and the CR Cache folder are all on a USB 3.0, 64 GB memory stick. The only thing on the laptop's (Windows 7) internal drive is the LR application. I turn on the external only when importing or exporting/printing and editing is done through the Smart Previews. This setup works smooth as silk for me, so I think you also should be able to work from the external.
    When you write "it does not allow me to create catalog nor retrieve catalog from external HDD," what do you mean? If you go to File/New Catalog, does the external not appear on the system navigation window that opens? If you go to File/Open Catalog, does the external not appear on the system navigation window that opens? If, with LR closed, you use Explorer or Finder to go to an .lrcat file on the external and double-click it, does this launch LR?

Maybe you are looking for
