is a file storage service, currently notable for providing 50 gb of free storage if you sign up with its Android client. (Or a few gb free otherwise.)

git-annex can use Box as a special remote. Recent versions of git-annex make this very easy to set up: WEBDAV_PASSWORD=xxxxxxx git annex initremote type=webdav url= chunk=50mb encryption=shared

Note the use of chunking; Box has a 100 mb maximum file size, and this breaks up large files into chunks before that limit is reached.

old davfs2 method

This method is deprecated, but still documented here just in case. Note that the files stored using this method cannot reliably be retreived using the webdav special remote.

davfs2 setup

  • First, install the davfs2 program, which can mount Box using WebDAV. On Debian, just sudo apt-get install davfs2
  • Allow users to mount davfs filesystems, by ensuring that /sbin/mount.davfs is setuid root. On Debian, just sudo dpkg-reconfigure davfs2
  • Add yourself to the davfs2 group.

      sudo adduser $(whoami) davfs2
  • Edit /etc/fstab, and add a line to mount Box using davfs.

      sudo mkdir -p /media/
      echo "  /media/  davfs   noauto,user 0 0" | sudo tee -a /etc/fstab
  • Create ~/.davfs2/davfs2.conf with some important settings:

      mkdir ~/.davfs2/
      echo use_locks 0 > ~/.davfs2/davfs2.conf
      echo cache_size 1 >> ~/.davfs2/davfs2.conf
      echo delay_upload 0 >> ~/.davfs2/davfs2.conf
  • Create ~/.davfs2/secrets. This file contains your login and password. Your login is probably the email address you signed up with.

      echo "/media/ mypassword" > ~/.davfs2/secrets
      chmod 600 ~/.davfs2/secrets
  • Now you should be able to mount Box, as a non-root user:

      mount /media/

git-annex setup

You need git-annex version 3.20120303 or newer, which adds support for chunking files larger than Box's 100 mb limit.

Create the special remote, in your git-annex repository. This example is non-encrypted; fill in your gpg key ID for a securely encrypted special remote!

git annex initremote type=directory directory=/media/ chunk=2mb encryption=none

Now git-annex can copy files to, get files from it, etc, just like with any other special remote.

% git annex copy bigfile --to
bigfile (to ok
% git annex drop bigfile
bigfile (checking ok
% git annex get bigfile
bigfile (from ok
