I generally back up the mp3’s that I buy off the net onto CD’s. Recently I bought a whole stack of DVD’s for a good price thinking I would use them when making little home videos. But I have found that the home vids are relatively small in size and therefore fit easily onto CD’s. So I haven’t been using the DVD’s for this purpose.
Now that I am running out of CD’s for my mp3 backups I started to wonder if it would be a waste/overkill to copy my mp3 back ups onto the extra DVD’s?
I use DVDs as a backup media. They hold a lot more than CDs. They’re great for convenient backups.
I backup by taking disk images. A HD disk image can be many GB. A compressed image of my system drive takes about 4 DVDs. That would be inconvenient (and more expensive) on CD.
I also backup my downloaded unicycling videos, my music files, and other data to DVD.
So John, how many CD’s would a DVD typically hold?
A single layer DVD holds about 4.7 GB
A typical CDR hods about 0.7 GB
So you can fit the equivalent of about 6.7 CDs on a DVD.
The downside is that sometimes it can be difficult to fill up all that space so you end up leaving some of it blank.
Thanks John. 
Maestro8, your point is well made! 
Sorry about the appalling usage of the much esteemed but often abused apostrophe here. My bad! There is simply NO excuse for such degenerate writing…and in the subject line no less! I stand (or sit, as it were) corrected.
It is difficult to take grammar corrections seriously from someone who doesn’t even bother to capitalize their own name.
Maestro8 is just upset at the world today because his chair was cold when he sat down for breakfast.
