| + | ==== Backup File Rotation ==== | ||
| + | TODO: We need to delete tarballs that get old, so we don't keep too many around. Would be nice to keep: 1 backup per day for 1 week (or 2 weeks); 1 backup per week for a year (or 1-6 months); 1 backup per month forever. | ||
| + | |||
| + | ===== MySQL ===== | ||
| + | |||
| + | Decided not to use ''mysqlhotcopy'', as it does not handle InnoDB databases, which some of our apps may require. So we're using ''mysqldump''. The ''--add-locks'' makes loading the resulting dump faster. The ''--allow-keywords'' allows fields to have the same name as SQL keywords. The ''--create-options'' includes MySQL-specific options on ''CREATE TABLE'' statements. | ||

| + | Take a look at [[http://jeremy.zawodny.com/mysql/ | mysqlsnapshot]] to see if it might work better for MySQL backups. Note that it has not been updated for MySQL 4.x or 5.x, but it's a Perl script, so it might still work. | ||
