2.2.1 beta server does not seem to use pre 2.2.1 file backup files on one client

I have had a UrBackup server running for some time and decided that I would like to see how 2.2.1 worked.

After having downloaded and installed it (over the existing installation), it looks like one of my clients no longer sees previously backed up files when backing up, so the first backup is copying everything over again.

I am getting a message of ‘No old file for “…”’ on every file attempted.

I’ve also noticed that it’s no longer writing to ‘/<backupDestination>/<ServerName>/<timestamp>/C/’, but instead to ‘<backupDestination>/<ServerName>/<timestamp>/C_0/’

Anyone else experiencing similar/is this expected/is this a bug?

Thanks

Know about no such issue. The C_0 is usually done at the client if there are two backup paths with the same name. Did you upgrade/change the client?
