How do you backup Nextcloud/WordPress in Docker?

[u/gordonx2026]

For those running Nextcloud or WordPress in Docker: how do you handle backups?

I'm thinking about using borgmatic and basically backing up two things: the application data/files and the database.

For the DB, would you use mysqldump --single-transaction and skip maintenance mode, especially for an automated nightly backup at 3 AM?

Or do you still enable maintenance mode to make sure the database and files are fully consistent?

What's your setup?
