+# Backup
+
+How to back up server services.
+
+## Prepare
+
+```sql
+CREATE ROLE backup WITH
+    NOSUPERUSER
+    NOCREATEDB
+    NOCREATEROLE 
+    PASSWORD 'tropcool'
+    LOGIN
+    ;
+```
+
+### Probably does not work
+Add in the file `pg_hba.conf` :
+```
+local all backup trust
+```
+
+Reload with `SELECT pg_reload_conf();`.
+
+### Probably works
+
+With _postgres_ : `GRANT SELECT ON ALL TABLES IN SCHEMA public TO backup;`
+
+Connect with `sudo -u postgres psql --username=backup --host localhost --dbname=kanboard_db`
+
+`pg_dump kanboard_db --username=backup --host=localhost > dumpfile.test`
+
+Does not work because backup can't access sequences.
+
+## Backup process
+
+### Disable websites
+
+Through _SSH_ on server
+
+```sh
+sudo a2dissite \
+kanboard.jovian-hersemeule.eu kanboard.jovian-hersemeule.eu-le-ssl \
+wiki.jovian-hersemeule.eu wiki.jovian-hersemeule.eu-le-ssl \
+gogs.jovian-hersemeule.eu gogs.jovian-hersemeule.eu-le-ssl ;
+sudo systemctl reload apache2 ;
+```
+
+### Backup local machine
+
+Through _SSH_ on server
+
+```sh
+cd /home/jovian/GitWork/DricomDragon/JovianLinux/ServerScripts/Backup/ ;
+git pull ;
+./j7backalllocal
+```
+
+### Retrieve backups
+
+On local machine
+
+```sh
+cd /home/jovian/GitWork/DricomDragon/JovianLinux/ServerScripts/Backup/ ;
+git pull ;
+./j7retrieve
+```
+
+### Enable websites
+
+Through _SSH_ on server
+
+```sh
+sudo a2ensite \
+kanboard.jovian-hersemeule.eu kanboard.jovian-hersemeule.eu-le-ssl \
+wiki.jovian-hersemeule.eu wiki.jovian-hersemeule.eu-le-ssl \
+gogs.jovian-hersemeule.eu gogs.jovian-hersemeule.eu-le-ssl ;
+sudo systemctl reload apache2 ;
+```
+
+## Automate
