Functions

Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

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.

-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.

Flip: rsync -aHAXxv --numeric-ids --delete --progress -e "ssh -T -c arcfour -o Compression=no -x" [source_dir] [dest_host:/dest_dir]

Alternatives

There are 3 alternatives - vote for the best!

Today, I would be wary of enabling RC4 anywhere, but I think today's default preference of ChaCha20 should be just as fast.
