This works well as > long as your daily backups will fit on one DVD or less. <snip> You criticized others for their solutions, yet yours also does not address his needs. You said "This works well as long as your daily backups will fit on one DVD or less." At first he was talking 1 TB, so definitely not 1 DVD. He then dropped to 50 GB, still a far, far cry from one DVD (unless blue ray), and said it would be monthly. He later clarified it was for his home server, and "I don't need incremental (I guess that is harder to do on multiple dvd mediums), just a full backup to dvds. I have personal images and video files I need to backup.". After all this you fault those who suggested a more practical solution (can't think of any situation where backing up 50 gigs to DVD would be the most practical solution) and turn around and suggest one that by your own admission is only practical if backing up one DVD per instance (week, month, whatever) when clearly the OP's requirements far exceed that. People provided valid advice based on their knowledge/experience. A lot of the advice attempted to sway the OP to consider a more practical solution given the facts he presented to the list. Some provided advice specific to an optical media solution. The OP was free to ignore or consider any or none of it. As pointed out by someone else. If you post something to a list as large and diverse as this, expect some to provide alternative solutions different than what you were planning to implement. I see nothing wrong with that. The OP was quite capable of responding with more info or re-affirming that despite the apparent impracticality noted by some to his choice for backup solution, it was what he wanted to implement for reasons that need only be known to him and therefore other advice although all valid will not answer his question. He didn't need a few other list members to jump in and assert on his behalf that we were not answering his question. That's when things went off the rails. Up until that point there was dialog between the OP and those suggesting solutions. If you want a very specific answer to a question, then you need to be very specific in formulating your question. Otherwise expect and learn to live with the fact that you will get diversity in the advice from others on these lists.
