Question backup / restore for noob
well i stated reading about backup/ restore on oracle and i'm a little confused ,
Anyone knows an article for beginners ?, All i want is to export database into a script (like in mysql) and then restore it on another server

Another question :
Does it work to make an backup from a remote server when connecting with a local client ?

You'd better use Oracle's native tools, EXP and IMP, you can find plenty of references on web and Oracle's docs, but basically you can use exp like:
1. Prepare a parameters file (exp_param.dat), with something like:
Quote:
BUFFER=100000
FILE="c:\export_YOURDB_YOURSCHEMA.dmp"
LOG="c:\export_YOURDB_YOURSCHEMA.log"
FEEDBACK=10000
OWNER=('YOUR_OWNER')
GRANTS=y
COMPRESS=y


2. Prepare a batch file with the appropriate commands:
Quote:
exp userid=YOUR_USERNAME/YOUR_PASSWORD@YOUR_INSTANCE parfile=PATH_TO\exp_param.dat


This can be easily scheduled, or you can run it by hand (parameters can be given interactively, there is no need for a parameters file).
Restore is done with IMP in a similar way.

BTW: you can backup a remote database and restore to a remote server (both are not the fastest options).
