这些log是用作备份的么？ 怎么配置这些log，貌似在不断增大，可能最后硬盘会不够用。
急求解答啊，呵呵

nagaregawa

transaction log file

备份：
# slapd_db_archive -h  /var/lib/ldap/

mahao_boy

哦 对了 现在这边配置的有两个openldap 一个provider 一个customer，我贴的是customer的数据列表， provider那边也有， 那么这个log就是transaction log file。 可不可以定期删除呢？或者有没有像mysql一样的配置文件里面规定binlog存储期限呢？

mahao_boy

呵呵 还有个问题
slapd_db_archive 这个工具备份openldap的时候 需不需要把ldap server停掉呢？或者改成readonly？
还是直接备份就行？
