Yes, I tried their script too. It doesn’t work.
Not many. That is a fairly small amount of data these days. I remember when things fit on 100KB diskettes, of a spool of paper tape. Now, it takes 4GB of DVD to hold programs, let alone their data.
I use Wordpress. There are plug-ins for that which do daily backups of the database and email them.
As for the other files, I find that shell access and the commands such as:
tar -czvf /tmp/myBackup.tgz ~
mv /tmp/myBackup.tgz ~
do the trick. It generates the backup file which ftp can then download. I don’t normally need to run the file backup since Wordpress does not keep much in terms of files. The only thing that I may need to backup is the photo collection, but since the photos are uploaded from my workstation anyway and they are baked up there, there is little need.
Most of the changes wth Wordpress are in the database and that is backed up daily to an off-site location via email.
Still, to each his own. You can write a small script and run it via cron to generate a daily backup. Use the /tmp directory to put the backup file out of the directory being backed up. Of course, I use my own name for the backup file. It is not the one that I am giving you here because the file names need to be distinct in the directory.
