Hi,
we use rdiff-backup to backup 4 servers. For backup media we use 10 WD
WorldBook NAS drives and cycle them through days.
We use NFS to mount a NAS disk on one of the servers (the file server),
then we run rdiff-backup to remotly backup a server to a 'local' NFS mount:
# rdiff-backup -v5 --force --ssh-no-compression --exclude-fifos
--exclude-device-files --exclude-sockets --print-statistics server2::/
/mnt/nas_backup/disk-01-D1
We used this backup for a couple of years now and apart from the NAS
disk slowness we haven't had much trouble...
However, we have replaced the file server recently. We still use
rdiff-backup 1.2.8, but now we get an error:

This happens after the backup has been running for hours (there's about
100GB of data and NAS disks are slow). Nothing has changed on the
'remote' server and we used the same rdiff-backup package on the file
server...
Searching through the web I thought this'posix1e' issue has been fixed a
long time ago...
Any ideas?
