Hi Ken!
You helpoed so much!
It is true: it is a server problem!
I could find the error log on CPANEL (under Log->error log) and identified the error. Than contacted Hostgator and they told me that that error was the Memory_limit that has a limit of 256M (I was asking for a LOT more).
I have to try to do the backup&restore during low charge moments of the server and again to say (I have said thousands of time) to the money guy, resposible for paying the bills!, that we need a better server plan.
Thank you again for your help.
Good spirit and good sharing for you from Portugal!
Mariana
