[Cialug] rsnapshot problem with compression

[Josh More]

Could the built-in OpenSSH compress be conflicting with rsync's?

Try running the server in debug mode and see where it dies.

Subject: [Cialug] rsnapshot problem with compression

Trying to get compression working on one of our backup jobs, .. but it
seems to be choking as soon as I add the --compress:

/usr/local/bin/rsync -a --delete --numeric-ids --relative
--delete-excluded \
    --compress --exclude=/dev/ --exclude=/mnt --exclude=/sys/ \
    --exclude=.gvfs/ --exclude=/lost+found/ --exclude=/media/ \
    --exclude=/proc/ --exclude=/tmp/ --exclude=/u/VM/ --exclude=.Trash* \
    --exclude=/u/Downloads/ --exclude=/u/VBoxBackup/ --rsh="/usr/bin/ssh
..

received request to transfer non-regular file: 3286 [receiver]
rsync error: protocol incompatibility (code 2) at rsync.c(336)
[receiver=3.0.6]
rsync: writefd_unbuffered failed to write 4 bytes to socket [generator]:
Broken pipe (32)
rsync error: error in rsync protocol data stream (code 12) at io.c(1525)
[generator=3.0.6]

Does anyone have a suggestion as to why compression is blowing up the
'conversation' and/or how to get it working properly? The backup DOES work
without compression, but it ran a week [plain DSL] without completing the
bacukp (it DID get about 40GB), so the only way to get a snapshot is to
get compression working.
