I had a bad few moments last night when the upgrade from Atahualpa 3.5.3 to 3.6.4 left me with the dreaded 'blank web page' syndrome. I exported the ATO settings to the .TXT file and tried the "delete bfa_ata4" button, which didn't help. The customizations I'd made to the theme settings were of course lost. I reverted to 3.5.3 and tried importing the saved settings file, but nothing changed -- the site still had the out-of-the-box default Atahualpa settings.
I was saved by my hosting company, who kindly restored the backup from the previous day. My research on this forum indicates that there may be an issue with spurious line breaks in the exported .TXT file, which I will look at.
Since the export of the settings to a text file may be unreliable, a backup method is needed. I know how to do an export of the MySQL database from the command line, and there are WP plugins that will do this as well.
My question is this: Is a full dump and backup of the MySQL database and a backup of the site files (especially wp-content) sufficient to back up all Atahualpa settings, so that the look of the site can be restored after a disaster?
