40.2.7 Data Volume and Hard Disk
Requirements
A sufficient amount of free space for all distributed data is required on the hard disks
of all involved hosts. Subversion and CVS require additional space for the repository
database on the server. The file history is also stored on the server, requiring even more
space. When files in text format are changed, only the modified lines need to be saved.
Binary files require additional space amounting to the size of the file every time the
file is changed.
40.2.8 GUI
Unison offers a graphical user interface that displays the synchronization procedures
Unison wants to perform. Accept the proposal or exclude individual files from the
synchronization. In text mode, interactively confirm the individual procedures.
Experienced users normally run Subversion or CVS from the command line. However,
graphical user interfaces are available for Linux, such as cervisia, and for other operating
systems, like wincvs. Many development tools, such as kdevelop, and text editors, such
as emacs, provide support for CVS or Subversion. The resolution of conflicts is often
much easier to perform with these front-ends.
40.2.9 User Friendliness
Unison and rsync are rather easy to use and are also suitable for newcomers. CVS and
Subversion are somewhat more difficult to operate. Users should understand the inter-
action between the repository and local data. Changes to the data should first be merged
locally with the repository. This is done with the command cvs update or
svn update. Then the data must be sent back to the repository with the command
cvs commit or svn commit. Once this procedure has been understood, newcomers
are also able to use CVS or Subversion with ease.
