No it's fine, how do you do it, from shell?
Most important thing I would say beyond anything else is test your backups - once a month, just extract the files / db to test the zip is intact, and one every 6 months do a full test restore.
I once had an issue where I had been backing a site up for ages, then when I needed a restore, I tried, only to find the files had been uploaded as ASCII instead of binary and they were all corrupt and unusable!
Also, it's good idea to make a script and keep 5 or 10 revisions, that's what I do now.
