Useful for transferring large file over a network during operational hours

That is, after running `vagrant ssh-config` to determine ports and ip's: vagrant ssh-config Host default HostName 127.0.0.1 User vagrant Port 2200 UserKnownHostsFile /dev/null StrictHostKeyChecking no PasswordAuthentication no IdentityFile /Users/romanvg/tmp/.vagrant/machines/default/virtualbox/private_key IdentitiesOnly yes LogLevel FATAL

Check the ssh_config file and set the variable: StrictHostKeyChecking no

traverses e.g. "/data/myhost1.com/myrsyncshare"; logs stderr and stdout. useful with cron.

Applying filter rules is what makes this a really useful command. It's usually a pain to figure out how to sync ONLY files matching a particular pattern, and often one reverts to goofy stuff like find .. -exec rsync .. The filter hides all folders from the transfer, so that only the matching folders that store the filename are left for the sync.

cloning root filesystem without suffering to possible interruptions. useful when moving a running system to a new partition. also works as a solid backup solution.

a : to keep files permissions --no-whole file : use rsync?s delta-transfer algorithm --inplace : writes the updated data directly to the destination file optionnal -> add --remove-source-files to mv instead of cp

Useful when upgrading my Linux distro and trying to copy only "settings" from the old home folder to the new one.

rsync will copy the source directory into destination and any subsequent run will synchronize only the changes from the source. Show Sample Output

This line unbuffers the interactive output of rsync's --progress flag creating a new line for every update. This output can now be used within a script to make actions (or possibly piped into a GUI generator for a progress bar)

While edtiing a project under git, it is sometimes nice to sync changes immediately to a test machine. This command will take care of this if you have inotifywait installed on the developement machine. Note the -R (relative) in rsync. with rsync foo/bar/baz user@host:dest/dir/ it will put 'baz' in dest/dir/foo/bar/ which is what we want. this can be turned into a function for additionnal flexibility : function gitwatch() { if [ -z $1 ]; then echo "You must provide a rsync destination" return fi while true; do rsync -vR $(git ls-files | inotifywait -q -e modify -e attrib -e close_write --fromfile - --format '%w') $1 done }

This command allows you to mirror folders or files with rsync using a secure SSH channel with a forced HMAC integrity algorithm. Use this if you are absolutely adamant about preserving data integrity while mirroring a set of files. --partial is for resumability.

Useful, when you need to backup/copy/sync a folder over ssh with a non standard port number

update the output of rsync after completing a file but don't create newlines, just overwrite the last line, this looks a lot better in scripts where you do want to see a progress-indicator, but not the lengthy logs this option is available since rsync 3.1.0 Show Sample Output

Functionally the same as the Microsoft Robocopy (https://en.wikipedia.org/wiki/Robocopy) command below but with the benefits of compression and optionally specifying a user. robocopy /e [//host]/source/path [//host]/destination/path Options: -a: archive mode - rescursive, copy symlinks as symlinks, preserve permissions, preserve modification times, preserve group, preserve owner, preserve device files and special files -hh: Numbers in human-readable K=1024 format. Single "h" will produce human-readable K=1000 format -m: don't copy empty directories -z: use compression (if both source and destination are local it's faster to omit this) --progress: Shows progress during the transfer and implies --verbose (verbose output) --stats: Summary after the transfer stops Show Sample Output

With these options rsync wont waste time copying over files that are already present and will show you whats going on. Optionally you can add in the option --Dry-run to see what will be changed without actually changing anything.

run rsync over ssh where root login is not allowed. You need to have "ForwardAgent yes" in your ssh config and run ssh-add before you login to the machine where you want to sync the files to.

This command will backup the entire / directory, excluding /dev, /proc, /sys, /tmp, /run, /mnt, /media, /lost+found directories. Let us break down the above command and see what each argument does. rsync: A fast, versatile, local and remote file-copying utility -aAXv: The files are transferred in ?archive? mode, which ensures that symbolic links, devices, permissions, ownerships, modification times, ACLs, and extended attributes are preserved. -/: Source directory -exclude: Excludes the given directories from backup. -/mnt: It is the backup destination folder. Please be mindful that you must exclude the destination directory, if it exists in the local system. It will avoid the an infinite loop. To restore the backup, just reverse the source and destination paths in the above command.
