You should not count on that method of backup anyway. If your site becomes damaged and you can't get into admin to restore it what will you do.
Best to learn how to backup your database using phpmyadmin or whatever your host provided you with to access databases.
And also to keep archived copies of your site as well. Not just a copy of the database.
I just go into my sql and export copies to my desk top. I hope I'm doing it right.
but what do you mean about keeping copies of the site?
Which files and/or directories should I back up on a regualar basis?
I know to keep members video,mp3 and photos backed up, but what else should I keep?
I had a forum crash one time, (SMF)
I deleted all the root files, dropped all the tables in mysql, reinstalled everything to knew, went back to mysqland dropped the new tables then imported the backup and it restored the forum!
Will dolphin work the same way?
