Dear Gurus,
Is there a way to automate the backup databases using pg_dump (like in SQL server)?

If you can come up with a way of automating the running of programs, then I imagine that might be possible. I have heard that a program called "cron" might be used for this purpose. -- "aa454","@","freenet.carleton.ca" http://cbbrowne.com/info/x.html People can be set wondering by loading obscure personal patchable systems, and sending bug reports. Who would not stop and wonder upon seeing "Experimental TD80-TAPE 1.17, MegaDeath 2.5..."? The same for provocatively-named functions and variables in stack traces. -- from the Symbolics Guidelines for Sending Mail

Why would you want to do ANYTHING "like in SQL server"! ;) You can do you back-ups very nicely using cron and a bash script: bash-2.05a$ crontab -l # DO NOT EDIT THIS FILE - edit the master and reinstall. # (/tmp/crontab.22116 installed on Fri Jun 13 10:41:06 2003) # (Cron version -- $Id: crontab.c,v 2.13 1994/01/17 03:20:37 vixie Exp $) 11 02 * * 1-6 /usr/local/bin/dump paid postgres@btober.com Slightly edited, but illustrates the point: bash-2.05a$ cat /usr/local/bin/dump #!/bin/bash # Script to dump a PostgreSQL database, producing # compressed tar file containing with pg_dump output. # Author: Berend M.
