Loading Dump File Into Subversion

[Jeremy Sutton <je...@thrivent.com>]

I am experimenting with migrating PVCS data to Subversion. I am using SVN 
Importer provided by Polarion 
(http://www.polarion.org/index.php?page=overview&project=svnimporter) . 
This tool creates a svn dump file which I then load into a Subversion 
repository.

The problem that I am running into is that the dump file created is 5.5MB 
but when I load it into subversion using

svnadmin load -q f:/svnRepos/Repository < dump-file.txt

the disk space used jumps up to 32.3MB. I have tried this many times and I 
get the same result each time. Is there reason why the repository would 
take more space than the dump file? 

I would appreciate any help you can give me,

Thanks,

Probably to do with how subversion stores revisions on disk... the file
system you are using may require allocating an entire allocation unit for
each file, and prior to SVN 1.6, subversion can use a few files for each
revision... so even if the revision only includes a 1 byte change, if could
be taking up many Kbytes of disk to store it.

Version 1.6 is reported to have a much better storage system which reduces
the on-disk requirements.

Another change you could look at is decreasing the allocation unit size for
your file system (but that may introduce other side-effects)
