cdr vrs cdrw and multi-sessioning

[zalman]

Hi all ,:wave:
I need to backup my documents folder with photo music and misc word documents
I use nero express oem its nero light ( really light !) not the nero express rom from 6.6
So my question is , If I have a checkmark in the multi-session square in my nero cd burning software can I keep using the same cdr or dvdr disc over and over for years
Untill it has 700 mb ..or 4.7 gig of data on it in the case of dvd r

Or do I have to use a new cd-r or dvd- r each time I need to add new files to my folders, new photos,or music cd's to media player playlist
( any new content of data since the last backup)

I know I can use cdrw/ dvdrw but I would rather not for long term backups because I believe they are not as stable as dvd r /cd r

I need to backup those new files to a stay current with the updates in order to protect against a hardrive failure. But hate to waste cd-r's or dvd-r's like that :blush:

You can use it until it fills up.

Some programs offer incremental backups which it seems that you want.
Nero Backup does, so does Acronis True Image.
