1. Have one computer that is the only one where stuff is added. Local calibre.

2. Use rsync or similar to copy/overwrite all changed files to a local server or NAS etc when calibre isn't running.

3. Then rsync from that to the other computers when calibre isn't running and must not have been running since 2. was done.

OR run the Calibre Content server on one computer.

Calibre or calibre library must be "local" but that can include a USB HDD, USB SSD, USB memory stick, firewire or SCSI or eSATA external drive, or SD Card etc.

You can't run calibre with a library on any kind of network drive or share.

Only save encrypted copies to Cloud as it's simply someone else's server with unknown security and backup. Best for sharing or websites or collaboration, not backups.

I have a separate USB HDD for backups (more reliable than SSD when disconnected) and the luxury of off-site (12 hour solar UPS on server wit a local UPS in a concrete garden shed via 1Gbps ethernet so in good weather indefinite power on IT). I used to leave a USB HDD with a friend and swap it.
