Backing up Nextcloud-Consistent Backup and Restore of Application Data
summary
Shows how to get a consistent Nextcloud backup by aligning filesystem snapshots with MySQL dumps, moving from naive file-copy to export-before-backup, maintenance-mode + after-job scripts, and finally an application-aware approach using the bareos_percona plugin to produce hot MySQL backups and enable point-in-time recovery. Demonstrates creating separate file and DB restore jobs (you need two restores), notes the plugin must be installed, and shows disaster-recovery and single-file restore workflows that do work end-to-end.
