# Crée une archive complète de l'application (BDD + fichiers + config) afin
|
||
|
|
# de migrer le CRM Ludikevent d'un serveur vers un autre.
|
||
|
|
#
|
||
|
|
# Contenu de l'archive :
|
||
|
|
# - dump PostgreSQL (pg_dump --format=custom)
|
||
|
|
# - dump Redis (RDB) si redis-cli est disponible
|
||
|
|
# - dossiers d'uploads : public/media, public/images, public/pdf, public/seo
|
||
|
|
# - var/storage, sauvegarde
|
||
|
|
# - fichiers de config : .env.local, google.json
|
||
|
|
# - manifeste (versions, date, hostname)
|
||
|
|
#
|
||
|
|
# Usage :
|
||
|
|
# ./bin/migrate-backup.sh # archive dans ./sauvegarde/
|
||
|
|
# ./bin/migrate-backup.sh -o /tmp/backup.tar.gz # chemin de sortie explicite
|
||
|
|
# ./bin/migrate-backup.sh --no-redis # ignorer Redis
|
||
|
