Version control system better suted than SVN

[hessiess at hessiess.com]

I have recently started storing all of my data (not config files) in a
subversion repository. Previously I was using unison to synchronise my two
computers, but annoyingly it won't work over the collages proxy server due
to SSH being blocked. SVN however does work because it can be used over
HTTPS, with the added advantage of version control, reducing the chance of
loosing data and also the need to store files which `may be useful
sometime'.

One problem I have had with SVN is it storing 2 copies of everything in
the working copy, which in the case of my home directory is much more
space than I actually have available on my laptop. So are there any
version control systems which, like SVN store all revision history server
side and work over HTTPS, but unlike SVN, only keep one copy of each file
in a working copy.
