What kind of failure are you seeing? What method are you using?
In the client bpc log, we have
- incr backup started for directory racine
- Got fatal error during xfer (rsync error: error in rsync protocol data
stream (code 12) at io.c(1556) [receiver=3.0.9.3])
- Backup aborted (rsync error: error in rsync protocol data stream (code

In the server's syslog, it's
kernel: [566863.920163] rsync_bpc[6209]: segfault at 7f6b29599e28 ip

That sounds similar to the problem that I’ve been having since March that I
can’t seem to sort out. I’m using rsync backups, but trying tar backups has
run into the same issue. My backups will hang, seemingly indefinitely—I’ve had
a backup sit unmoving for 7 days before. Sometimes, killing that backup and
running a new full will give me a reprieve. But I’ve not been able to find or
fix the underlying cause to this point.

Well, yes. rsync 3.1.x has a bug which might be directly affecting your
transfer, and sounds related to your use case:

If this is the case, either upgrading (or downgrading) should take care of the
issue.
It's not a process hanging, just plain crashing (which may come from the
same bug or not). Since it's rsync_bpc that goes over the cliff, it may
not be related to an rsync bug.
We learned that we are using an old release of BPC4 (4.0.0). We're going
to upgrade it to the latest release, just to clean matters.
This looks like a known issue that I had with BPC 4.0alpha I think was
the version, it only impacted directories with a large number of
entries, or servers with a large number of total files/dirs (I forget
which). In any case, it has been solved for a long time, please upgrade
to the latest version.

Adam
