Brilliant - Many thanks Dani.
I have tried the back up script I referenced in a previous thread, and it works brilliantly - it is a 'push a button' solution, and can be configured to back up selected databases, tables, row ranges from tables - what ever, and either send you the export gzip by email, or put it in a folder on your server or both. I have already implemented it on three databases.
If you could tie that in with a backup task scheduler (I just don't get cronjobs) it would put the easy management of data backup in our hands, and would add value to any job we signed off on with our clients.
Appreciate you having a look at this!
