make_backup.sh – effettua chiamate via HTTP per creare i backup

make_backup.sh:

# Backup su dominio 1
wget –spider http://www.******.**/db-bck.php?dbname=Sql*****_*
wget –spider http://www.******.**/db-bck.php?dbname=Sql*****_*
wget –spider http://www.******.**/db-bck.php?dbname=Sql*****_*
# Backup su dominio 2
wget –spider http://www.******.**/db-bck.php?dbname=Sql*****_*
# Backup su dominio 3
wget –spider http://www.******.**/db-bck.php?dbname=Sql*****_*

db-bck.php risiede sui diversi domini (vedi sopra) genera un dump del database.
La procedura è molto spartana ma fa il suo dovere, naturalmente deve trattarsi di piccoli database altrimenti non funzia. Però per tanti piccoli domini dove i database sono si e no qualche Mb va benissimo…
