This answers why I was no longer able to post to the other one. smile

I was asking about the importance of doing a back-up before upgrading from 7.0 to 7.1 as my server space is very tight in adding back-up data to it.

I also asked how often is the back-up actually needed when doing this kind of an upgrade.

I had always previously successfully done upgrades without doing any back-up, therefore, I am, or was, thinking of doing the same thing again.

As a result of the replies in the other thread, what is the absolute minimum back-up required in case the back-up is needed?

Will backing up the database tables only be sufficient, or do I need to back-up the whole site?
