[edit] Overview

rsync is a Linux command-line application for synchronizing (i.e. making sure both copies have the latest versions of all files) a directory tree between two machines.

This is a seed article. You can help HTYP by watering it.

• Use rsync to back up a directory tree of files: a basic how-to

[edit] Examples

Copy a directory structure from relsource on machine to reldest on the local machine:

rsync -Pav user@machine:relsource reldest

• a is for 'archive', which is short for pr which are 'preserve' and 'recursive'
  • p ('preserve') preserves timestamps, permissions, etc.
• v is for 'verbose', which means it tells you what it's doing
• P is for 'progress' and 'partial', which allows for resuming an incomplete copy

[edit] Notes

• To keep files in sync in both directions, you have to run rsync in both directions as well; there is no single command to synchronize two directory trees.
• This probably does not also remove destination files deleted from the source.
