Rsync¶
Trailing Slashes¶
The one thing I can never remember: what it means for source and/or target to have trailing slashes.
Target - makes no difference¶
As long as the target specifies a directory, it makes no difference whether you write it with a trailing slash or not. I’ll write a trailing slash from here on, just to emphasize that I’m copying things into a directory.
Source no slash¶
With no trailing slash on the source, the tail part of any name in the source gets created on the target. E.g.:
$ rsync path/to/file.ext remote:target/
$ ssh remote ls target
file.ext
creates file remote:target/file.ext
$ ls path/of/dir
a b c
$ rsync -a path/of/dir remote:target/
$ ssh remote ls target
dir
$ ssh remote ls target/dir
a b c
creates directory remote:target/dir containing whatever files were in path/of/dir.
Source with slash¶
If the source is a directory and is written with a trailing slash, then no part of the directory path is copied to the target, only the contents of the specified directory.:
$ ls path/of/dir
a b c
$ rsync -a path/of/dir/ remote:target/
$ ssh remote ls target
a b c
Rsync to remote systems using ssh¶
Example:
rsync -Hlrtz --delete-during -M--fake-super /etc/ hostname:path/etc/
-H –hard-links: preserve hard links
-l –links: copy symlinks as symlinks
-M –remote-option=XXX: send OPTION to the remote side only
-r –recursive: recurse into directories
-t –times: preserve modtimes
-z –compress: compress during transfer
–delete-during: receiver deletes during the transfer
–fake-super: store/recover privileged attrs using xattrs
Assuming ssh hostname works…
