unless you've got a very small amount of data, I would recommend using
rsync (or rsync over ssh for encryption), as it can modify and backup
only what has been modified very quickly.
Something like
rsync -avv --delete -b --suffix='.1' --stats --progress \
"/storage/folder" \
"/storage/folder1" \
"/storage/folder2" \
"/storage/folder3" \
"[EMAIL PROTECTED]::dest_folder/backup_foler" > ~/.rsync.log
...is what I use via a daily cron each night on my servers (it doesn't
really delete the last modified files, but renames them as .1 in case a
problem in the day occur. During the next synchronization, those .1
files are, this time, really and definitely deleted. Other options are
either cosmetic or verbose for the logs.
And once a week, the rsync server has another cron that make a full
weekly backup; until it has 4 full weekly backups, the last one becomes
the monthly backup, and the 3 others are deleted, and so on.
That's what I do ... never said it was absolutely perfect.
