Calibre2OPDS - why so many file uploads??

I have been keeping my books and C2O on Dropbox and all working brilliantly.

HOwever I am now in the process of tidying up the metadata which, of course needs me to then regenerate ned C2O files.

I wanted to access these from a second computer and rather than wait for dropbox to sync I decided to copy the dropbox folder to USB drive and copy from that to second (remote location).

Over the weekend I tweaked a few more books and so regenerated C2O again - now I have it set to minimise file changes and when I resync'd data to USB drive it found 175 files had changed - fine, OK

Then I noticed poor old drobox had been working full tilt for 2 days and STILL had 26,000 file to upload???? Huh????

Surely just the 175 should have needed reuploading to DB?

Anyone else seen this - anyone know why??

Not sure why you were getting so many files. It sounds as though you did something that made DropBox think all the files had changed. The stats in the calibre2opds log will tell you exactly how many files were changed in that particular run - and that is the number that DropBox should sync as a result of that run. In fact the Minimize Changes options was added specifically to help DropBox users and it certainly seems to work fine for me. I wonder if you did a run WITHOUT the Minimize Changes option set - that could have the sort of effect you describe. With the 2.4 release onwards there is also the synclog file generated in the calibre2opds log folder which should give you an exact list of the files that were copied (or not copied) to the new catalog (and thus need syncing). Looking at that might give an indication of what is happening.

If you are using the 2.5 beta 1 release then you may want to also use the feature that has been added to reuse the calibre cover.jpg files for thumbnails and cover images rather than generating new images optimised for that purpose. This means there are less files stored in the library thus saving some space (although there is more network trafic when browsing a library as the cover.jpg files are normally larger than the optimised images that calibre2opds would otherwise generate).

I have Minimise number changed ticked and Do not save Bandwidth unchecked. I do have reprocess ePub data ticked but would have thought this would only affect changed books??

I don't mind about the cover jpgs as loads of room on dropbox and prefer quicker load when browsing

Here's part of the log

Looking at that log, about 30,000 files ended up being copied.

I am guessing that the epub reprocessing did result in many files being changed looking at the elapsed time that it took. In the 2.5 beta 1 version the statistics written to the log have been extended and would have told you how many files were re-processed so you could be more certain. Note that files get re-processed if the .opf file in the book's folder is later than the epub file. Did you perhaps tell Calibre to do a backup as that would update all the .opf files?

Weird. I only updated 80 or so book details. Dunno why so many had ePub data redone??

Turned off reprocess the next time and just reconverted those I had changed ePub to ePub. Still resulted in about 6000 files getting reuploaded to Dropbox?? When I checked it was all the authors, books, tags etc etc needing reupdating too :-(

The trouble is that when you have a big library then adding even a single book can result in quite a few files being changed as the contents of the multi-page catalog sections get shuffled up. I cannot see any way to avoid that I am afraid. You can suppress the generation of any catalog sections that you do not want to try and help reduce the number.
