Linux command: rsync

Create local backups

rsync -avzXAS --delete /Origen/ /Destino/

Note: if origin ends with '/' it will copy the contents of the directory else it will copy the directory

The code above will synchronize the contents of Directory1 to Directory2, and leave no differences between the two.
If rsync finds that Directory2 has a file that Directory1 does not, it will delete it.
If rsync finds a file that has been changed, created, or deleted in Directory1, it will reflect those same changes to Directory2.

• -a – The archive option = -rlptgoD
  • -r – (recursive into directories)
  • -l – copy symlinks as symlinks
  • -p – preserve permissions
  • -t – preserve modification times
  • -g – preserve group
  • -o – preserve owner
  • -D – preserve device files and special files
• -v – increase verbosity
• -z – compress file data during the transfer
• -X – preserve extended attributes
• -A – preserve ACLs (implies -p option)
• -S – handle sparse files efficiently
• --delete – if the file is deleted from the source directory, delete it from the target directory

From your local machine

rsync -chavzP --stats user@remote.host:/path/to/copy /path/to/local/storage

• -c, --checksum skip based on checksum, not mod-time & size
• -h, --human-readable output numbers in a human-readable format

From your local machine with a non standard ssh port

rsync -avz -e "ssh -p $portNumber" user@remote.host:/path/to/copy /local/path

Or from the remote host

rsync -chavzP --stats /path/to/copy user@host.remoted.from:/path/to/local/storage

Remote backups

rsync -av –delete -e ssh /Origen/ user@192.168.11.21:/Destino/

with password and port settings

rsync -av –delete -e 'ssh -p 12345' /Origen/ user@192.168.235.137:/Destino/

Changing permissions and ownership

pgrep -f "rsync -avz --chown=turing:www-data --chmod=Du=rwx,Dgo=rx,Fu=rw,Fog=r --log-file=${LOG_FILE}" > /dev/null || rsync -avz --chown=tur$│

Remove source files after succesfull transfer

rsync --remove-source-files -azv /path/to/Download/*.avi laptop:~/Download

Follow symlyncs (-L)

rsync -L /path/to/Download/*.avi ~/Download

Exclude

rsync -avz --exclude 'dir1' source/ destination/
rsync -avz --exclude 'dir*' source/ destination/
