have you only got a single full backup for that host, or did full backups work up to some point in time, when they started failing? And why does BackupPC do an incremental backup after a failed full backup? Shouldn't the full be retried until it succeeds? That doesn't sound right.

Would that lead to a zombie ssh process? See the ssh_config man page for how to send keepalive messages (TCPKeepAlive or ServerAliveInterval) to keep your firewall happy. What is your $Conf{RsyncClientCmd}, or rather, what commands show up in the XferLOG files for incremental and for full backups? Have you looked at the XferLOG for a failing full backup?

I'm not sure how that exchange happens. Is it one large list with all the details at the start (i.e. file list + checksums for all files)? Does the receiver really need to compute checksums for *all* files (with --ignore-times), even those the sender side would send anyway due to changed attributes? Wouldn't that mean reading those files twice? That would certainly explain why checksum caching makes such a difference (maybe I should switch it on ;-).
