Tools for backing up server files
There are many ways to back up server files that contain Moodle code and moodledata. Site Backup for Low-tech Users also has information on this subject.
Rsync in linux
For the files, you can use rsync regularly to copy only the changed files to another host:
rsync -auvtz --delete -e ssh mysshusername@example.com:/my/server/directory /my/backup/directory/
If you want to run the cronscript at the machine you are running Moodle at you have to use following rsync syntax
rsync -auvtz --delete -e ssh /path/to/local/folder/ remoteuser@remoteserver:/path/to/remote/folder/
If you do not want the root mailbox be spammed by statusmails of the rsync use:
rsync -autzq --delete -e ssh /path/to/local/folder/ remoteuser@remoteserver:/path/to/remote/folder/
FTP
If your Moodle hosting provider does not allow ssh (or just do not provide it) and you have simple [File Transfer Protocol FTP] (a File Transfer Protocol) access with a username and a password you can also use:
mkdir /tmp/remote-folder curlftpfs ftp://username:password@ftp.your-site.com /tmp/remote-folder rsync -auvtz --delete /tmp/remote-folder /my/local/backup/folder/ umount /tmp/remote-folder rmdir /tmp/remote-folder
Wget
wget can be used to backup the entire database. For example use something like these commands(tested on cPanel web interface):
wget --http-user=username --http-password=password http://your-site.com:2082/getsqlbackup/moodle.sql.gz
and the entire backup of the Moodle code tree:
wget --http-user=username --http-password=password http://your-site.com:2082/getbackup/backup-your-site.com-`date +"%-m-%d-%Y"`.tar.gz
Some customization might be needed for other web interface like (webmin?)
