Depends on your systems. My wordpress blogs have a plugin that emails a back up to me every day/week (differs blog to blog) I also have a desktop program called SqlYog that can automate backups of remote databases (ie websites)
need more information. are you talking about backing up just your database? what database are you using?
As Sarah said, it depends on your system. There's no "one size fits all" solution to database backup.
hello all Make incremental backups Create Java archives Find documentation to use other backup devices and programs Encrypt your data..
the best solution I've found is to dump the databases on my vps using rsnapshot, automysqlbackup and amazon S3
Do it via a backup script called 'automysqlbackup' (Google iT) place in the root dir of your webserver and add database names you want to back up and change any other settings to suit, then set up a cron to automate. Good luck
