Major Description
In our system, we need to do data backup and restore for apacheds. For now, we use the ldapsearch and ldapadd command to do BR function. We use ldapsearch to backup apacheds data to be a ldif file and use ldapadd to restore the data. But when the ldif is a little big, I always found that the data can't be restored successfully, but the ladpadd command showed that the data can be added successfully. No exceptions for ldapadd command. But the restored data didn't exist in the node. This bug only happened when the ldif file is a little big. I mean if the data entry greater than 500 entries. But the node for backup and restore is using mavibot partition. Because I found so many problems for jdbm. So I change it to mavibot partition. Another question is that do you know is there some good way to do the data backup and restore for apacheds?
Below is the exceptions from apacheds when problems happened:
