Subversion good for DPT?

[Karl Kuehn <la...@softhome.net>]

	I apologize if this is dumb question, but I work supporting a group of 
users that include a number of graphics artists, and I was wondering if 
anyone had any thoughts about using a versioning system in such an 
environment.

	The reasons I am thinking it might be a good idea is that we can have 
multiple people working on different files in a collection at the same 
time, for example one person working on a Quark document while another 
touches up some of the images that are referenced from the other. And 
at times we need to have the same document open on two machines (one 
for modification and one for printing). Right now we are using a fiel 
server to do this, but at times it would be much faster if everyone had 
their own local copies, but syncing everything by had can be a pain, 
especially with graphics artists (not necessarily the most organized 
people).
	My thought was that I could script a check-out in the morning, and a 
check-in in the evening. I am also thinking of writing a small 
GUI/script to allow them to check-in at various points in the day. This 
would give us fairly up-to-date copies of the projects on each computer 
without a lot of intervention by me, and a way of retrieving older 
versions in case something got corrupted (a real nuisance with Quark).

	My biggest concern is that we are talking about project folders that 
can be 10+ Gigabytes, and since things are going into a database this 
is likely to get a bit bigger than that. I was wondering if anyone has 
any experience with this. Most likely the files that will change will 
only be a few ones, each in the 250MB range, and for one of the users 
around fifteen  < 20 MB files. I was wondering if Subversion stores 
everything as diffs, and also if anyone has experience with Photoshop 
and Quark files interacting with Subversion.

	If anyone has any experience in this I would love to hear from you.

Subversion does indeed store the changes as deltas, even if the files 
are binary.  How much space this actually saves will depend upon the 
program that writes the files (Photoshop or Quark).
