无法还原OrientDB备份

Question

我无法从备份还原OrientDB数据库。 我使用的是OrientDB 1.2.0版（此备份来自2012年11月），该备份是由OrientDB（相同版本）使用内置备份实用程序生成的。 我正在尝试使用OrientDB控制台将备份还原到新数据库：

create database remote:localhost/dbname root password local graph
import database backup.json

但是，当我运行这些命令时，在控制台中出现以下错误：

Importing indexes ...
- Index 'dictionary'...Error on database import happened just before line 22258, column 6
com.orientechnologies.orient.core.exception.OConcurrentModificationException: Cannot update record #0:1 in storage 'dbname' because the version is not the latest. Probably you are updating an old record or it has been modified by another user (db=v2 your=v1)

所有记录均正确导入，但在索引上失败。 我有15个以上同一数据库的备份，而且它们都有这个问题，因此似乎它们都没有损坏。 如何还原数据库？ （如果需要，我可以不必修改JSON。）

当尝试使用本地模式而不是远程模式时，出现另一个错误：

看来问题在于我的旧群集ID与新数据库中的ID不匹配。 也许有一些创建选项会影响默认情况下创建的集群？

Answer 1

事实证明，问题在于该数据库是使用OrientDB 1.2.0版导入的，但是是使用1.0.1（或1.0.0）创建的。 JSON文件将1.2.0版列为engine-version ，但这是备份它而不是创建它的引擎。 在尝试了Lvca关于使用本地模式的建议之后，我发现群集ID不匹配。 从那里我猜测版本号可能不正确。 因此，即使我使用1.2.0服务器和1.2.0 Java库运行数据库，该数据库也从未被“升级”为使用新的1.2.0模式。

感谢Lvca向正确的方向推进。
