backup
Hi,
My Calibre library size like 100 Go (75k of .epub) but it takes too long to backup: ![]() my config: OS: Debian GNU/Linux 12 (bookworm) x86_64 Host: Mini IT13 Kernel: 6.9.12-1-liquorix-amd64 CPU: 13th Gen Intel i9-13900H (20) @ 3.001GHz GPU: Intel Raptor Lake-P [Iris Xe Graphics] Memory: 3346MiB / 31858MiB I'm trying to backup on SSD NTFS |

Export/Import is meant for data transfer between two computers, not for backup. For backup just copy both the library folder and the configuration folder, and paste them to your backup drive. Going forward, you can make incremental backups (updating only the files that have been changed) via FreeFileSync, using its mirror (one-way) option.

Calibre Export creates a custom Spanned Zip
100G is a huge amount of data to process and compress. The old way was to manually backup the ENTIRE CONFIGURATION FOLDER and Library folder(s) Export just keeps all the pieces together. Including multiple Libraries if Calibre is configured that way Another common way is to use something like FreeFileSync IN MIRROR MODE ONLY After the initial run, it does an incremental (just the changed pieces) |

Given how many posts we've had here complaining about not being able to restore their libraries from the export/import files, I would not use that method for backup.

Also, you can delete the export files as you won't need them. https://freefilesync.org/download.php |

Can someone clarify about the "configuration" folder? I don't seem to be able to find it.

On Windows, it's usually in User/AppData/Roaming - the entire folder named calibre. If you're not on Windows, click Preferences -> Miscellaneous -> Open calibre configuration folder, to see where it is.

Thanks, found it. There is also a "Calibre-ebook.com" folder.
I needed a current backup of my books, and in the past used the Export option. My use of Windows file structure is very rusty, and it seems more difficult than it was in the past. |

The config folder is the one named calibre. I don't know what the other one is, something to do with the viewer when used separately, perhaps?

Because the configuration folder can be relocated via the CALIBRE_CONFIG_DIRECTORY environment variable, I always tell people to use the button. I keep mine configuration folder adjacent to my calibre libraries and related folders and files. Quote:

As a retired IT professional, I am reluctant to rely purely on increment backups. It is far too easy to propagate a, undetected, error. Then you're up the creak without a paddle.
Personally, while I use rsync as my main backup strategy, I also use Calibre's Export to do a full backup once a month. (My library is small enough that I can do this in a reasonable time.) Copies of this backup are keep on: the original machine, a USB stick and in the cloud (as an offsite backup). Just because I'm paranoid doesn't mean Murphy isn't out to get me, As to the OP; have your tried running TAR on your library directory? |
