无法还原 OrientDB 备份

Question

我在从备份恢复 OrientDB 数据库时遇到问题。我使用的是 OrientDB 版本 1.2.0（此备份是从 2012 年 11 月开始的）并且备份是由 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 控制台将备份恢复到新数据库：

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

但是当我运行这些命令时，我在控制台中收到以下错误：

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)

所有记录都正确导入，但在索引上失败。我有 15 个以上的同一个数据库备份，它们都有这个问题，所以它们似乎不太可能全部损坏。我怎样才能恢复我的数据库？（如果需要，我可以修改 JSON。）

尝试使用本地模式而不是远程模式时，出现不同的错误：

问题似乎是我的旧集群 ID 与新数据库中的集群 ID 不匹配。也许有一些创建选项会影响默认创建的集群？

Answer 1

事实证明，问题是数据库是使用 OrientDB 版本 1.2.0 导入的，但创建时使用的是 1.0.1（或 1.0.0）。 JSON 文件将版本 1.2.0 列为 engine-version，但那是备份它的引擎，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后，我发现集群 ID 不匹配。从那里我猜测版本号可能不正确。所以看起来即使我运行使用 1.2.0 服务器和 1.2.0 Java 库的数据库，数据库也从未 "upgraded" 使用新的 1.2.0 模式.

感谢 Lvca 在正确方向上的推动。
