Local library file, pointing to cloud-based ebooks?

[Timmeh]

Hi all,

I have calibre running nicely on a dedicated Ubuntu server (via docker). The server has a 2TB hard drive. Up until now I have been able to keep my ebooks stored locally at /opt/appdata/calibre/library. However, I have started acquiring comics and my hard drive space is decreasing rapidly, along with other media.

So, I have mounted a cloud system to hold the books/comics but I'd like to keep my metadata.db file stored locally for stability reasons. The cloud directory is located at /mnt/ebooks.

The main issue is that when I create a new library in the /mnt/ebooks directory and begin to add my ebooks, it becomes unstable and corrupts each database I create.

I have found a thread which says that it is possible to keep the metadata.db file separate from the ebooks folder which is encouraging (https://www.mobileread.com/forums/sh...d.php?t=254287) however after hours of trying, I cannot find a way to do achieve this. Essentially I'd like /opt/appdata/calibre/library to store the metadata.db and point to ebooks stored at /mnt/ebooks.

Please could someone advise how I can achieve this as I have been trying for a few hours and cannot seem to get it to work and cannot find any literature. It's probably something obvious but I can't seem to find it.

Thanks in advance!

Don't use the Cloud, except to exchange files or host a website.

Even my Android tablet has a 256G micro SDXC card (€28 inc shipping).

I have my Calibre library on my laptop and backup copies on USB HDD, my local server and my off site backup.

I only use local files and import ebooks & PDFs to the local storage of the Calibre Library, as recommended.

2tb should be all you ever need, even for a gigantic comic collection. Move other,non calibre stuff to your cloud and keep calibre local. You can also backup calibre into cloud but don't run it in there.

As for your original trickery request, windows has symbolic links which can fool a program into seeing networked storage as local, but I don t know the equivalent for Ubuntu. And it's safer not to do that for any calibre stuff

Thank you for the advice.

From an academic point of view, how do environment variables work with Calibre on Linux? I found the windows-based 'CALIBRE_OVERRIDE_DATABASE_PATH' env variable. Will this work on Linux and if so where would it be used?

TIA

Yes, as the FAQ indicates the EVs work on all supported platforms.

For how to, google "how to set environment variables in linux".
