consider merging with others

restic has a similar project, called [fakedatafs](https://github.com/restic/fakedatafs), with similar goals. fakedatafs works as a FUSE filesystem to provide a dataset to benchmark backup software.

obnam has its own tool to generate backup data called... [genbackupdata](http://liw.fi/genbackupdata/). the design is similar to borg's, but like fakedatafs, it is also deterministic.

i was wondering if any thought has been given to reviewing or even merging with those projects instead of maintaining (now at least) 3 different projects in parallel?

if we want a standardized test suite for backup software, it seems to me we should aim at standardizing the corpus generation as well! :)

a similar issue was opened against the restic project in https://github.com/restic/fakedatafs/issues/3

结合 restic 的 fakedatafs 和 obnam 的 genbackupdata，审查现有的 backupdata 项目，并从链接的 fakedatafs issue 开始了解相关讨论。确定它们的目标和设计是否可以合并或标准化；当项目形成有文档记录的决策和范围时，这项工作就完成了。
