excessive disk usage by revisions?
Hi,
I've been looking at a space utilization issue and am a bit confused. Just looking at the size of the revisions in the db/revs directory and only looking at the 2.2M size revs I see about 3GB+ of disk space consumed just for Feb 2:
ls -lhrt /misc_sourcectrl01/svnrepositories/qcfusion/db/revs/14? | grep "Feb 2" | grep 2.2M | wc -l
1408
I checked out one of the revs and only see 180k with du -sk of the checked out directory? I planned to look at what they are doing until I saw this. Why the 2.2M revision and only 180k of space on the checkout?
[root@dadbcu09 qcfusion]# svn log -v -r 142001 file:///misc_sourcectrl01/svnrepositories/qcfusion

Thanks for any help with this,

Do you have lots of files or subdirectories in those directories that
were modified? (hundreds of thousands+)
Subversion does not save the deltas of directory changes and we
saw similar behavior when we had one single large directory
with a huge number of individual files...
