About
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.
Related Pages
- backup software
- rclone: rsync-like application that works with many more protocols including low-priced cloud storage
user pages
- user:Woozle/rsync: full command, showing actual options we use, including machine names
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
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.
- To use rsync in an automated script (e.g. for backups), see keyed login for password-less operation.
- Tentatively, to delete source files after copying to target, use
--remove-source-files.
