BSD Linux


An rsync-based backup tool, enterprise-level features. Created in http://brainarray.mbni.med.umich.edu, and used in many groups, MBNI itself uses it to backup 150T data from one Windows file server and multiple Linux file servers daily, and each backup takes about 5 hours.

Please stay tuned, our next innovation is to use those ditched LTO tapes to knit a sweater probably.

  • Unmodified files use only one space no matter how many backups are kept, and user-moved files can be linked back to the same space to save space even further
  • User can retrieve backups without administrator's help, because the backup is on a regular file system
  • Strict owner/permission control, backup file can have the same security setting as its source
  • User can find file by name in backups more quickly than command 'find'
  • Can backup Windows through samba, and can have granular owner/permission control for each sub-folder
  • Graphic report
  • Centralized control, no software installation or daily operation on client side
