Archiving Projects

["Bryan D. Andrews" <ba...@trendcore.com>]

We have a repository that has a lot of older projects not in use
anymore. We would like to make a copy of the repository and then clean
out the current repos with only the most current projects. Is this a
correct approach (as opposed to trying to start with a fresh repos)?

Our repos is about 5 gigs right now and without the dead projects and
their history its probably a quarter of the size. 

Is there any info / any links that someone could direct me to on this?

There are notes in the Subversion manual page about splitting up 
repositories. Splitting them is in fact feasible: what's an amazing pain is 
flushing files that accidentally got copied to the wrong place and which 
don't belong anymore.

If you're not re-arranging the repository entirely, *do not* allow the 
"svnadmin dump |  [ filter content ] | svnadmin load" steps to renumber the 
repository, it'll just drive anyone with a checked out copy nuts.

Possibly, but you may not notice the speed difference in the face of local 
operations like checksumming local files when doing commits.

could you perhaps autocreate a new repository after a certain number  
of versions and have everyones local area point at that (through  
symbolic links maybe)? that way you will end up with older versions  
of the project in a repository that could be archived away?

because of the nature of our project we're only interested in the  
last 20 or so versions of our design (this is binary data, not ascii)  
so having a repos that contains the entire history doesn't make sense  
for us.

if the above were possible, do people think it would be quicker to  
update/commit etc as well as yielding smaller repositories ??

thx

i think you have to decide why you want to clean. is it because you want
to save disk space or is just to get a "cleaner looking" repository ?

if the former, then you have to realize that the the svn db never really
shrinks only gets larger and larger no matter what you commit.

if the latter, then it's probably a matter of style or taste. we
actually created a "recycle bin"-project in our root, so people
(including non-developers) had one last chance to view what's being
deleted in an quick way. after that we delete the "recycle bin"-project
itself.
