Copiar archivos del servidor ubuntu a nextcloud sudo cp -R /ruta/de/tus/archivos/* /var/www/html/nextcloud/data/<tu_usuario>/files/Destino/

sudo -u www-data php /var/www/html/nextcloud/occ files:scan --path="<tu_usuario>/files/Destino"

Nota para o siguiente: Ha funcionado sin crear directorio destino ni dar permisos. No copies archivos cuando el usuario esté accediendo a Nextcloud; podrías corromper datos. Asegúrate de que el directorio de destino (Destino) exista previamente, o créalo con: mkdir /var/www/nextcloud/data/<tu_usuario>/files/Destino chown -R www-data:www-data /var/www/nextcloud/data/<tu_usuario>/files/Destino

Eliminar bloqueos base de datos de Nextcloud Nextcloud a veces deja bloqueos en la base de datos que impiden operaciones de archivos. sudo mysql -u root -p

Selecciona base datos Nextcloud USE nextcloud; DELETE FROM oc_file_locks WHERE 1; EXIT;

INSTALACION SNAP sudo snap install nextcloud

1. BACKUP-RESTORE USANDO SNAP SAVE-RESTORE https://github.com/nextcloud-snap/nextcloud-snap/wiki/Backup-and-Restore

Backup. stop Nextcloud snap sudo snap stop nextcloud save Nextcloud snap sudo snap save nextcloud start Nextcloud snap sudo snap start nextcloud copy/move snapshot (*.zip) in /var/lib/snapd/snapshots to wherever

Restore copy/move snapshot (*.zip) to /var/lib/snapd/snapshots discover snapshot-id using snap saved restore snapshot sudo snap restore

Deleting snap snapshots Procedure discover snapshot-id using snap saved delete snapshot sudo snap forget

2. BACKUP-RESTORE USANDO NEXTCLOUD.EXPORT / NEXTCLOUD.IMPORT https://github.com/nextcloud-snap/nextcloud-snap/wiki/How-to-backup-your-instance

Exportar/backup

nextcloud.export Se guarda una carpeta con fecha y hora (ej:20190121-153921,) dentro de /var/snap/nextcloud/common/backups/.

Se puede crear un tar o tar.gz (comprimido) sudo tar -czf 20190121-153921_nextcloud-backup.tar.gz /var/snap/nextcloud/common/backups/20190121-153921

Importar/restore Extraer el archivo tar o tar.gz sudo tar -xvf 20190121-153921_nextcloud-backup.tar.gz

Colocar la carpeta extraida (nombre fecha y hora) en: /var/snap/nextcloud/common o /var/snap/nextcloud/current/

sudo nextcloud.import path/to/backup/dir.**

sudo mv 20190121-153921_nextcloud-backup.tar /var/snap/nextcloud/current/ sudo chown -R root:root /var/snap/nextcloud/current/20190121-153921/

Opciones: -h: Display this help message -a: Include the (non-default) apps -b: Include the database -c: Include the config -d: Include the data (can be quite large)

Q. Can exporting specify the data directory? A. Not directly, but you should be able to use a symlink. For example, creating a symlink from the data directory to /var/snap/nextcloud/common/nextcloud/data

Q. Can I somehow export/import my HTTPS certs? A. Yes, everything related to them is stored in the /var/snap/nextcloud/current/certs directory, so copying it and preserving its permissions and owner works.
