Thank
you for all of your input, I have found it invaluable in creating my proposal. I
will be proposing the disk/tape solution.

Subject: RE: [ActiveDir] Backup StrategyPersonally I think USB drives are a bad idea. Not so much from the reliability standpoint as from the index and catalog standpoint. USB drive will probably have to be labeled individually and you end up having some admin/operator manually keeping track of where all the drives are located (e.g. vault or on-site).Most, if not all, tape system / backup software do indexing and cataloging as part of their software and will read bar-codes tapes. They will tell you what tapes to pull and what to bring back from vault. And if you have an ATL or tape loader, the software will do the ejecting / requesting automagically. Our ATL system does this and it makes what we call the "vault run" a snap.I agree with the other posts... for the money you will spend on USB drives and the possible potential tracking problems, go with the standard SAN and tape loader solution.-Stuart FullerP.S. The other part of this question you should be asking is what is my recovery plan? If the USB drives are the way to go, then how does that plan work when I need to recover something? Also if you are using a DR vendor like Sungard or Iron Mountain, how will USB drives and your plan work with their systems??

Subject: [ActiveDir] Backup StrategyI am sorry if this is off-topic, but I greatly respect the opinions/suggestions that come from this list.I am working on a backup strategy for my company. We have just over 300GB of data to back up. I have been asked to estimate storage capacity/cost required to keep data for 1 month and 3 months, so this means that we will need between 1 and 3 TB of storage. The current backups are stored on a SCSI array and the plan is to use USB drives for offsiting our data. This means that we will need 4-12 300GB USB drives to store our offsite data.I personally do not like this solution and am in favor of a disk/tape solution; using a disk array for onsite backups and using tape for offsite backups. The company prefers disk-based backup because of its speed. However, I think that disks are less reliable than tape and that using USB drives is not an enterprise-class solution (I have also heard that those 300GB USB drives are not too reliable). Not to mention the fact that these drives are bulky and our server room is already pretty cramped.Does anyone have any suggestions? Are my concerns valid? Is my suggestion of disk/tape the best solution?_________________________Daniel DeStefanoPC Support SpecialistIAG Research345 Park Avenue South, 12th FloorNew York, NY 10010T. 212.871.5262F. 212.871.5300Measuring Ad Effectiveness on TelevisionThe information contained in this communication is confidential, may be privileged and is intended for the exclusive use of the above named addressee(s).
