口是心非：切换到“二级备份链”

当我的备份驱动器未连接时，我运行了它duplicity，它删除了很多缓存sigtar和manifest文件：

Synchronizing remote metadata to local cache...
Deleting local /Users/justin/.cache/duplicity/a7190bc7f0d9f083cbc7e03931a8c95f/duplicity-full-signatures.20160608T054248Z.sigtar.gz (not authoritative at backend).

现在，当我运行口是心非时，它会尝试执行完整备份，而不是查找现有的增量备份。

运行duplicity collection-status file:///Volumes/DuplicityBackup/显示我的备份链已经变成了“次备份链”，并且有一个空的“主备份链”：

$ duplicity collection-status file:///Volumes/DuplicityBackup/

我怎样才能解决这个问题？（即删除空的“主备份链”，使用“次备份链”）

答案1

几周前我遇到了这个问题，对我有用的是擦除口是心非的缓存并从后端手动删除所有新的主链文件。
