Hi All,

Operating databases is not my forte and I am new to it.  For me a
database is a tool to use to help with my main work (so is a computer if
it comes to that).  I can ill afford to lose any data.

I run two databases for personal purposes and have a two machine
network.  The "old" machine I use for back up purposes.  I have run the
dump command and produced two .sql files which I have transferred to my
old machine via ftp.  Both have successfully re-created their databases
on my old machine.

I have now added to both databases and wish to do a subsequent back
ups.  

Do I just run the dump command on each database again please?  Will this
overwrite the original .sql files or should I delete (rm) the original
.sql files on my current or working machine and start again?  On the old
machine do I delete the first .sql files and ftp the newer ones and then
just run the psql command to re-create the updated databases?  Do I have
to drop the first re-created databases before attempting to restore the
updated .sql files after sending them via ftp from my current machine to
my old machine?  I could just try to see what works (as I did when
starting and running postgresql in the first place) but I worry about
losing my data in an ill-conceived experiment.

I am running Red Hat Linux 6.2.

Thanks for any help.

Cheers,



Les.
