Thanks in advance

Look for me like problem with files, broken hdd? Corruped filesystem?
Something is definitly wrong.

This is what Andrew Ferguson (maintainer of rdiff-backup) wrote in
response to a similar problem a couple of years ago:

"Given this error, and especially since one client is failing and three
are working, I would be suspicious of the failing client's hardware
(probably RAM or hard disk). Are all of your clients backing up to one
server? What is the setup here?

CRC is the Cyclic Redundancy Check and is a way of checking the
integrity of a data stream.

Were there any other messages logged from rdiff-backup? Perhaps in the
rdiff-backup-data/error_log files?"

And here is what someone else wrote about this error:

"This problem has come up many times on the mailing list, and so far there
is not a good fix for it... usually it appears when one of the .gz files was
incomplete. Try this:

find rdiff-backup-data/ -name '*.gz" | while read a; do
echo -n "$a:"
gzip --test "$a"
done

This will tell you which files are bad. In our case, we had a problem
with the mirror_metadata files. Search the archive for specifics, but
basically I copied a good mirror_metadata over the bad mirror_metadata and
crossed my fingers. It worked for us, though I do not know the
implications here. After doing this surgery, you might try a restore of
the past few backup dates and make sure it is successful. Worst case, you
rm-rf rdiff-backup-data, though you will loose your increments."

HTH, Dominic
