[TriLUG] Using gzip to backup postgres to tape

[Andrew Perrin]

Thanks, but gzip actually handles tar format fine; sending the same output 
to a file instead of tape works without problem.

To confirm that it's about writing to the tape, I tried this:

cat 2006-02-21.backup.log  | /bin/gzip -c > /dev/nst0

gzip: stdout: Invalid argument




which shows that something about gzip's output makes the tape drive choke.
