Would absolutely love a plugin or module within the platform that allows for export and import of galleries, generally to support webhosting changes for instance.
Had a look at https://piwigo.org/forum/viewtopic.php?pid=181772 and that's just way too complicated for my skillset and cognitive abilities. I'm currently manually uploading over 28,000 images to some 500 albums and it's going to take forever. Would not like to do this every time there's a hosting change.
Export should also include any descriptions added plus of course all the photos and photo metadata.

From experience a php based database backups scripts could take a while and timeout or appear to be hung. Subscribed to see if someone would ever attempt to build something like this.
Do you have a backup strategy in place? It shouldn't be much different to migrate or backup your installation from one host to another if your hosting provider has filesystem dumps and MySQL dumps with automated database backups.
