C'est la raison pour laquelle j'utilise plus innodb..
ovh
Je n'utilisais pas innodb, et j'utilisais ce rsync dans le temps, plus maintenant

ovh> Et si tu utilises InnoDB, tu peux tout foutre à la poubelle, ton backup est illisible nul part ailleurs

Moi un jour je backupais en effet mes db mysql en rsyncant directement les répertoires /var/lib/mysql/mabase comme un bourrin sur la machine de backup
Et ça avait l'air de marcher

Pour le repertoire, du incrémental avec rsync, et pour le SQL suffit de pisser un mysqldump dans le tas...
Pour la DB, je ne sais pas si MySQL supporte le hot-dumping, mais si oui, autant également utiliser rsync également, ce sera nettement plus rapide.

yop!
Je voudrais faire un petit script de backup "générique" qui s'occuperait de backuper une db MySQL et un répertoire.
Le but est de pouvoir faire des backups déparés et automatique des différents sites intranet/internet dont je m'"occupe".
Le but est de faire un backup de la DB et du root folder. Si je peux garder les droits, c'est encore mieux. Le target est un folder share samba ou un FTP.
A la fin, je voudrais un truc à qui je donne un fichier de config qui contiendrait
DB_Server :
DB_Name :
DB_User :
DB_Password :
Files-Folder :
Backup_Target : smb/ftp
Backup_Path :
Backup_User :
Backup_Password :
Full_copy_to_Keep :
Ce genre de chose existe déjà?
Si oui, où?
Si non, c'est compliqué?
Merci pour vos idées
