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
- T: turn off pseudo-tty to decrease cpu load on destination.
- c arcfour: use the weakest but fastest SSH encryption. Must specify "Ciphers arcfour" in sshd_config on destination.
- o Compression=no: Turn off SSH compression.
- x: turn off X forwarding if it is on by default.
rsync -aHAXxv --numeric-ids --delete --progress -e "ssh -T -c arcfour -o Compression=no -x" user@<source>:<source_dir> <dest_dir>
rsync -aHAXxv --numeric-ids --delete --progress -e "ssh -T -c arcfour -o Compression=no -x" [source_dir] [dest_host:/dest_dir]
Ones I've used
$ rsync -aHAxvP --numeric-ids --delete --info=progress2 \ firstname.lastname@example.org:/export/lvm-raid0/500MB.file /export/raid1/ $ rsync -aHAxvP --numeric-ids --delete --info=progress2 -e "ssh -T -c aes128-ctr -o Compression=no -x" \ email@example.com:/export/lvm-raid0/500MB.file \ /export/raid1/
My 1st one was just as fast as others.
