I guess you have a lot of time and a lot of bandwith, and never worked
from far away with limited access, limited time (15 minutes of
connectivity only ?) and under a lot of pressure under production
server.

I know all of this tools, and belive me that I know how to use them !
But sometimes the real way is to make backup using the most basic
tools arrives with the database. But I guess you do not have
experience with such things...

Secondly, not all of the databases saves the blob the same way even on
minor versions ! and sometimes it even modify the binary. I once had a
sub version of a database that had a bug that added two bytes
additional to binary blobs... when you read it with that version,
everything worked, but when you moved to a newer/older version, it did
not.

There are many horrors with binary blobs. They are bad practice, and
can cause many problems with your data ! But I guess you do not have
experience with real life programming of binary blobs or working with
databases... Otherwise you would have experienced with problems when
using blobs... so please gain some experience in real life before
jumping on things.

You must known your RBDMS or leave such task to DBA.

For example: with Interbase / Firebird you can have more than one database
file (a few years ago because file size constraints but now for device
contention) and you should use gbak and new for FB nbackup instead of file
copy.

In Oracle, apart from IMP/EXP and new (for 10g) data pump, you can use RMAN
and other database methods.

I don't known much about postgres but I guess has nice backup utilities.

If you are too lazy to learn how really your RDBMS works don't recommend bad
practices.

Amm.. that's what the backup mechanism does !
I'm talking about database grids, and some of the database engines.
Unlike Interbase and mysql, that when you use them as a single
database you can copy the files/directory, on many database engines
and data grids, that's the only way that the database allows you to
backup anything.
