Question

我使用以下命令创建了一个OrientDB备份：

./backup.sh plocal:../databases/DemoDB demo demo demo.zip

现在，为了测试我的备份是否成功，我已经删除并重新创建了我的数据库，现在我正在使用控制台导入它：

IMPORT DATABASE "/Users/erik/databases/demo.zip"

我现在受到以下错误的欢迎：

Started import of database 'plocal:../databases/BestProgrammingBooks' from /Users/erik/databases/demo.zip...

她发生了什么事，我该如何解决这个问题？我在Mac上使用OrientDB 2.1.5。

给定备份，要恢复数据库，正确的操作是RESTORE，而不是IMPORT。 IMPORT是指您希望导入先前使用EXPORT命令导出的数据库。
