Thank you very much.
b) Is there a global setting file that can be used to enable
directory/property deltifications? Or will we have to update the fsfs.conf
file for each newly created repository in order to get this feature?
In 1.8, you'll need to toggle this for each new repository manually.
I'll cobble something together with "grep", "sed/awk", and "find" then
to monitor (and update) our fsfs.conf files.
As for the --deltas option, that has nothing in the world to do with the
types of deltas we're discussing here. (As an aside, I would highly
recommend that, unless you need your dumpfiles to be smaller, avoid the
--deltas option. The performance penalty of using it isn't worth it.)
Right now, the size of our dumpfile directory is 207G, while the hotcopy
is only 104G. So the size savings could be big for us. The hotcopy
backup is still our preferred solution, with the dump files being a
worst-case fallback.
#2 - revision property (revprops) files packing
a) Will there be a "svnadmin pack" command like there was for SVN 1.6? Or
will we need to do a full dump/load of the repository to pack the revprops?
The existing 'svnadmin pack' command will govern both revision and revprop
packing, and will keep the two in sync with each other. 'svnadmin upgrade'
will also take the opportunity to synchronize the packing status of the
revision properties with that of the revision backing files.
Thanks, the svn book is light on details of what exactly counts as
"minimum amount of work needed" for "svnadmin upgrade".
