DVD for backup

By egoodman ·
I am currently backing up on a tape backup every night. We need to quit overwriting the previous backup and start saving everydays backup for E&O. My nightly backup is about 3gig and the cost of tapes makes it expensive. Am thinking of writing to DVD and re-using the tapes...any comments?? Can you get 9 gig on a blank DVD now???? I have been reading about 9.4GB storage media available now

You can put more than 1 backup per tape depending on the backup program you are using. Just append another backup to the previous one. Make sure your backup application supports this and that you test restoring.

With respect to DVD backups there is no standard format for DVDs yet, so compatibility down the road may be a problem.

Thanks Norm

When you enter into the area of compliance, ie E&O, you are best to move with caution so as to not invalidate that which your attempting to comply with. Compliance is a cost of doing business and while the initial reaction is that it is "expensive"and "a waste" it needs to be clear in everyone's mind that this is, at this point at least, a necessary business expense in order to provide the risk transfer that is incumbent with the E&O stipulations. For accounting purposes the cost of the media should be associated with the policy cost as it is a direct element of the policy.

So once everyone gets comfortable with that then you can move onto attempting to find solutions which reduce the cost, maintain the data integrity, provide for satisfying the "stewardship" aspects and ta da make you a hero.

Before you get too far along in the process you do want to inquire and resolve whether or not the DVD media would be acceptable as a substitute and if there are any restrictions that need to be considered. Often times you will find that the policy provider/underwriter may not be as forward thinking in acceptance and certain proofs have to be offered up to keep the policy intact. No how much "common" sense or reality is evident, it sometimes just won't be accepted or accepted with only certain stipulations.

(continuing and concluding above, not sure why it doesnt show me or give me the option to comment at this point. oh well)

As an example, I am aware of one situation where the media HAD to be a write once, single session in order to meet the compliance features. Now this was wasteful since there was not that much on the media, but it was simply required and could not be budged. In that case CDR was acceptable, CDRW was not acceptable.

As to DVD of 9.4 gb the answer is yes, it is a dual sided media, basically 4.7 on each side, and has started coming into the main stream during the past 6 months or so.

However, this is early stage in this market and prices are all over the board, particularly when you do the generic - name brand compares.

Also there are a number of factors that you're going to want to get worked out, rock solid, again keeping the why, compliance, in mind. The least of which is how do you restore the media to prove up something. I have seen numerous incidents where the idea was we have it therefore it is ok, only to find it couldn't be reproduced when needed. Also software issues, tranfer times, burn times, security, all have to be nailed down.

Not sure what your media costs are, but you will still have media cost, you will have new hardware costs and you will still have an additional Daily process, so you have to run the numbers carefully to see your ROI and breakeven points.

But the idea is one well worth exploring and a nice little solution package would be a great item to come up with.

Hope that helped.
