Re: How long do your svn dumps take

What I find is even better is to do the dump/load across a network to
a different server... as it saves trashing the disks... alternatively
dump/load across disks is better...

I tend to favour dump/load via pipe rather than dump to file load from file...

And perhaps the best yet is to do the dump-load via svnsync... that
way people can continue to use the older repo until you're ready to
cut across as svnsync will let you do things incrementally

(Although dump can be incremental too, so you can achieve the same via
dump-load as long as you are careful about tracking revisions...
svnsync will track the revisions for you)

Our largest repo is about 20GB, and that took 24 hours to load from
dump file but our backing file system is on a DRBD backed file system
(to give us a HA subversion server)
