I'm trying to recover the Couchbase data from the database files of a 2.0 dev preview 3 Couchbase instance (on an OpenVZ VPS server running Debian 6) that can no longer be started.
I've tried using cbbackup, but that fails, saying that it cannot recognize the database files. This may not be indicative of anything, though, as from tests on newly-created databases on clean installations, cbbackup still fails with the same error on all the OpenVZ instances I've tried.
I've tried copying the database and install files to a different server, running the executables / installing the software on top of the existing files, and that never resulted in success.
Are there other ways to extract the data?
