# rsync

|
## Ordering
|
||
|
|
|
||
|
|
### Local to local
|
||
|
|
|
||
|
|
```
|
||
|
|
SOURCE_DIR > TARGET_DIR
|
||
|
|
```
|
||
|
|
|
||
|
|
### Local to remote
|
||
|
|
|
||
|
|
```
|
||
|
|
LOCAL_SOURC_DIR > REMOTE_TARGET_DIR
|
||
|
|
```
|
||
|
|
|
||
|
|
### Remote to local
|
||
|
|
|
||
|
|
```
|
||
|
|
REMOTE_TARGET_DIR > LOCAL_SOURC_DIR
|
||
|
|
```
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rsync -a <dir_to_copy_to> <dir_to_copy_from>
|
||
|
|
```
|
||
|
|
|
||
|
|
## Expanding directories
|
||
|
|
|
||
|
|
The following:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rsync -a local_dir target_dir
|
||
|
|
```
|
||
|
|
|
||
|
|
Will create `/target_dir/local_dir` at the target. In other words it will nest
|
||
|
|
the actual directory you are interested in within what you have named the
|
||
|
|
target.
|
||
|
|
|
||
|
|
To avoid this, add a slash to the source directory, viz:
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rysync -a local_dir/ target_dir
|
||
|
|
```
|
||
|
|
|
||
|
|
Now, at the target, there will just be `local_dir`.
|
||
|
|
|
||
|
|
## Standard options I use
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rsync -vzP
|
||
|
|
```
|
||
|
|
|
||
|
|
- verbose output
|
||
|
|
|
||
|
|
- use compression (only really useful when running rysnc over a network)
|
||
|
|
|
||
|
|
- display progress
|
||
|
|
|
||
|
|
- preserve partially copied filed and resume if network connection interrupted
|
||
|
|
|
||
|
|
## Archive mode
|
||
|
|
|
||
|
|
Use "archive mode" when specifically wanting to create a backup of a directory
|
||
|
|
(i.e. for long term storage rather than immediate use).
|
||
|
|
|
||
|
|
```sh
|
||
|
|
rsync -a
|
||
|
|
```
|
||
|
|
|
||
|
|
Archive mode is an umbrella for the following flags:
|
||
|
|
|
||
|
|
- `-r`: recursive
|
||
|
|
|
||
|
|
- `l`: copy [symlinks](./Symlinks.md) as symlinks
|
||
|
|
|
||
|
|
- `p`: preserve permissions
|
||
|
|
|
||
|
|
- `t`: preserve times
|
||
|
|
|
||
|
|
- `g`: preserve group
|
