RE: svnsync: E175002: REPORT request on '/<ROOT>/!svn/rev/<N>' failed

Hi Daniel.

Thanks very much for your help!
I'll try getting in touch with CloudForge.
In the meantime, to address your questions:
* No, I have no previous backups - this is my first attempt to create one.
* Yes, I am able to check out version 71 - svn checkout %SOURCE_REPO%_at_71 reports no errors.
* Yes, if I repeat the sync command, it fails with the same error:
        E:\svn>svnsync sync file:///E:/backuprepo_01
        svnsync: E175002: REPORT request on '<ROOT>!svn/rev/71' failed

Thanks again,

-Nick

The error code is SVN_ERR_RA_DAV_REQUEST_FAILED, which doesn't add information.

I wouldn't resort to that yet. Do you have previous backups of these revisions? Does «svn checkout %SOURCE_REPO%_at_71» succeed? If either of these works, you should be able to work around the error in r71.

The standard next step is to look in the server's log for errors. If you don't have access to it yourself, then you should contact your hosting provider. If you do this, you hopefully wouldn't have to discard the first 70 revisions (not to mention that based on the information available, we can't rule out the possibility that _later_ revisions will have the same error).

As I said, my first recommendation is to talk to your hosting provider.
If you do this, you might skip the middleman and ask them to run 'svnadmin dump --deltas foo' and send you the resulting file. If you they don't figure it out, _then_ would be the time to start doing fancier things (wireshark, workarounds using previous backups and/or 'svn checkout', etc).

Cheers,

Daniel
