You need to back up your Library someplace OFF the computer / hard drive to save your books with their metadata.
Export/Import on the Library Icon can do this, but it always does a FULL, which can be time/space consuming. IMHO do that whenever you make changes or install new Plugins (those are in the config folder)
Use a file sync program to incrementally update a separate Library copy.
Freefilesync seems to do a fantastic job.
Always STOP Calibre to do a Mirror (1 way) sync
Don't have sync active while Calibre is running.. avoid 2 way sync. it fights changes  |
Thank you. I appreciate knowing for certain that I should not have Calibre open when doing a mirror sync. I back up the books on a portable hard drive and do a separate back up of the config file on another portable hard drive.
I do have a conundrum related to backups. What I really am doing is managing the book libraries for my grandchildren. I found that if I sent them books to add on a flash drive that the info that I had created for these books did not get transferred. Instead, I have a portable drive for each family that I update by mirroring my data. They just plug it in and copy books to their devices. This has a downside if they make changes or add columns as I believe my mirror update will erase these. Doing a two-way update, however, led to corruption of the files ultimately. Why I don't know, but FreeFile Sync ran into problems deleting files and then stopped, reporting that the drive was "dirty". I had to reformat the drive and so am now only using the mirror option. My knowledge and understanding of these softwares that I use is frustratingly inadequate. I like that my grandchildren want to personalize the records with their own ratings and other comments, but don't know how to preserve this. Suggestions?
