[rdiff-backup-users] strange traceback

[Sacerdoti, Federico]

Hi,

I am using rdiff-backup sucessfully to backup very large NAS servers
(~3TB each). The setup is one primary nas, one secondary nas.

I use the "local" method of rdiff backup, where I mount the secondary's
volume on the primary via NFS, then tell rdiff-backup to use the
mountpoint as the destination.

Things have been humming along as expected for several weeks, until last
night. My nightly rdiff-backup script emails errors if rdiff-backup
returns non-zero. All 5 of my NAS primary servers emailed this
traceback:

(I apologize for the loss of newlines). Note these are indepedant
servers and the tracebacks are identical. It is possible we experienced
a network partition between the primary and backup last night.

Thanks,
Federico

rdiff-backup:did not succeed: 

 Previous backup seems to have failed, regressing destination now.
