Was wonderig if someone could help. I got a failure on one of my
partitions yesterday night complaining about the error in the subject
heading. I thought it may be a problem with the actual partition on the
server Telsun4 (see info. below). Therefore I umounted the /ccmbackup partition and then fsck'd it and it
was fine.
Any ideas would be helpful

The seek errors are probably a result of an active filesystem. When you unmounted it, and fsck-ed, it was fine again.
If it happens only now and then, don't worry. Try to not run any programs that do heavy input/output during the backup, if possible.
If it happens frequently, use snapshots, if your OS permits it, to freeze a filesystem in a few seconds, and make a backup of that snapshot. Or use gnutar instead of ufsdump, which, at least, manages to make a consistent backup of everything that did not change -- files that did change *may* be inconsistent, and gnutar warns which ones (logfiles that are only appended, are nevertheless consistent).
