Filesystem Backup

Hello All,

I am in a fix and need help. I am reinstalling postgresql server on my linux workstation and\ I did a filesystem backup of ../pgsql/data/*, but when I deleted the data directory and reconstructed it from my backup (without the reinstall, just to check if things would work) I started seeing errors (I mv' the data directory twice...)

The first error was "postmaster.opt.default not found in ../pgsql/data/postmaster.opt.default' and when I created an empty file it said '../pgsql/data/base/template1/pg_class not found'.

Am I missing something? are there any other steps to a filesystem backup?
