the problem with backing up a database incrementally is that as the
database grows the backups bloat up as they do not get any benefit from the
incremental backup.
with a database, it is usually better to replicate the database to another
host and then do periodic dumps.
web pages are very typically static on disk. it is a good practice to make
your website completely read-only so there would be no writes to local
files. The only writes should be to the cache and to an attached database.
I would suggest you do periodic dumps of the database and then backup the
directory where you put those dumps. I would also suggest that you
replicate the database to another machine. Keep in mind that if you are not
going to have an hot spare database server, you can replicate a heavily used
database to very modest hardware because it doesnt need to server requests.
The nice thing about online replication is that you can replicate and then
shut down the second database and do the dump from there so you never have
to shut down the main database.
