I know that there are binaries (excutable files) stored along with the sources so those are one big item at a time, I guess... >It sounds like a good plan to make a new repository and re-initialize the >sync.

Regarding repository names, are they stored anywhere internally in the repo or is it just the top level directory name? If it is "just a name" then I should be able to rename the existing mirror dir and then create a new "pc" repo destined to be set to become a synced repo according to the directions in the svnbook. And then presumably the sync will go from there. One item I am not sure of is the "syncuser" password, it seems to be in use yet I see nothing about it in the batch command used and I don't even remember it now since I originally set it up back in 2018...

Right, I have already spent a lot of hours trying to figure out the repercussions of the server crash... I have a 1000/1000 MBPS fiber connection here but I believe the company connection is a bit slower. I worried about any interruptions during the first sync potentially destroying the new repo... > >Even if you loose connectivity again (and end up with a stale lock), you >should be able to steal the lock and re-start from where it stopped - you >don't need to do this in one big operation. > Hopefully it won't stup...
