[英]Does duply back up the state of a file when it is read or when duply command is started?
I want to back up 100 TBs of data.我想备份 100 TB 的数据。 The backup task should take 30 days given my computation power and bandwidth.考虑到我的计算能力和带宽,备份任务应该需要 30 天。 But the data are not stagnant.但数据并没有停滞不前。 During the progress of back up, data will be modified/created/deleted within the source directory.在备份过程中,数据将在源目录中被修改/创建/删除。
Question is will duply/duplicity back up the state of files when a file is read or when backup is initiated?问题是在读取文件或启动备份时是否会重复/口是心非地备份 state 个文件?
duplicity will use the file state at the point in time when the file is processed during the backup . duplicity 将在备份期间处理文件的时间点使用文件 state。
Note: as a user application duplicity is not capable to enforce file system consistency, meaning if the file is readable, but currently open in another application and written only partially, this inconsistent state will be backed up.注意:作为用户应用程序,口是心非无法强制执行文件系统一致性,这意味着如果文件可读,但当前在另一个应用程序中打开并且仅部分写入,则此不一致的 state 将被备份。
