### The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)
#### This creates an archive that does the following:
**rsync**
(Everyone seems to like -z, but it is much slower for me)
- a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
- H: preserves hard-links
- A: preserves ACLs
- X: preserves extended attributes
- x: don't cross file-system boundaries
- v: increase verbosity
- --numeric-ds: don't map uid/gid values by user/group name
- --delete: delete extraneous files from dest dirs (differential clean-up during sync)
- --progress: show progress during transfer
**ssh**
- T: turn off pseudo-tty to decrease cpu load on destination.
- o Compression=no: Turn off SSH compression.
- x: turn off X forwarding if it is on by default.
**Original**
```sh
rsync -aHAXxv --numeric-ids -P -e "ssh -T -o Compression=no -x" user@<source>:<source_dir>/ <dest_dir>/
```
**Flip**
```sh
rsync -aHAXxv --numeric-ids -P -e "ssh -T -o Compression=no -x" [source_dir/] [dest_host:/dest_dir/]
```
