RE: New subversion version on new server?

Greetings Andreas, thanks for your reply!

Unfortunately we used a simple rsync to "backup" the svn repository files,
this will ofc change in the new server with help from the information you
provided.

The bad thing is that we only kept a 2 week backup of the backupfiles, and
the error ofc happened during vacation, which was longer than 2 weeks. My
best guess is that the oldest backup is a rsync of the repository with the
corrupt file(s), meaning these file(s) are missing as the blocks the reside
in cannot be read.

1. What happens if I do a "svnadmin dump" on a rsync copy of a real
repository?

2. As one of the repositories has a corrupt file block within atleast one of
the db log files (possibly other files as well), is there anything we can do
to solve this?

3. Would a good "backup" solution be to run a svn dump on all repositories
on a daily basis? We'll also keep the backups for several months now :)

The output from "svn dump" can be loaded afterwards by any kind of database
backend. So you can perform a "svn load" also on a FSFS based repository.
Only "svn sync" (on Subversion 1.4 and above) assumes that the same
repository type is used on all mirrors.
