duply 在所有命令上都失败，断言 filecount == len(self.files_changed) AssertionError

无论我在这个重复配置文件上尝试哪个命令，它总是会出错。

duply database status
duply database bkp
duply database purge

它们都返回类似于以下内容的跟踪

这评论对我有帮助解决这个问题

“删除最后一个损坏的备份”

所有.part文件都是不完整的备份

ll /srv/mysql/logs/duply_backup/duply_cache/duply_database/*.part

删除不完整的备份。如果您想更加保守，输出会告诉您哪些文件导致了问题。

Processing local manifest /srv/mysql/logs/duply_backup/duply_cache/duply_database/duplicity-full.20171010T231503Z.manifest.part

否则你可以清理所有*.parts

rm /srv/mysql/logs/duply_backup/duply_cache/duply_database/*.part

删除这些文件后它可以正常工作。这些都是不完整的备份，应该以任何方式清理。
