We work with large numbers of TIFF files and they need to be archived. I have been archiving them onto external drives, but need to get them on to DVD's. I have been looking for a more automated solution.---any ideas?  Thanks.

You could use a backup program and DVD-RW's.  It will keep prompting you as each one fills up until you are finished.

BTW.... I use Veritas and it works quite well, but I would assume NT Backup will do the same.

Besides backup, any IT division should have a disaster recovery plan. You will find a few tips below relating to the development of such a plan and to what issues one should pay special attention in the course of backup planning.

Yes, however the problem with a backup solution like Veritas or NT Backup is that you will then not be able to search for and retrieve a single TIFF from the DVD without having to reload the media catalog for the backup.
If you are simply looking to have a disaster recovery solution or if you almost never need to directly referrence images from the backup then this solution is great.

If however you wish to generate DVDs which are readily available as 'Nearline' storage of media which you work with or may refer to from time to time (eg if a client wishes to produce something based on prior projects, etc...) you will be better off just burning the files to a particular DVD and then referrencing that externally.
Unfortunately this is not an easy thing to automate without extensive windows scripting knowledge.  The easiest method I use is to simply place the files to be archived in a 'NextDVD2Burn' folder... when that folder gets to be ~4.4GB (you need filesystem room you'll have a better idea of how much once you burn one DVD since it depends on how many files and/or folders are involved) - just burn that DVD.  You can then use a 3rd party tool such as WhereIsIt? (my personal choice) to browse thumbnails, and search for the location of a particular image.  This can be loaded on multiple workstations if necessary - the catalog files can be shared and loaded by multiple users.  Once you find the image desired... just pop in the DVD indicated... and off you go!

At the present time I am not aware of a system that will automatically archive files and provide essentially a multi-volume incremental backup with an optical media... but I could certainly be wrong.

If you just need a backup for safe keeping... use backup software... if you're trying to have a near-line solution to an ever-growing mass of files - it may not be as easy to back up the files the first time, but if you have to access them fairly often you will save that time and more on the other side. ;)

The Catalog will stay in the Backup software and on the DVD's.  You can also just dump them to thier own DVD if you desire.  I don't know the author's requirements for retrieval or speed of access, so either solution might be best in certain circumstances.

JESUS CHRIST!!!......i've never ever known a person with over 1 Terrabyte of data
(many of my friends don't know what TB is!!!).....what are you storing.
Any way.....you can burn the data into MANY 8.4 GB DVDs......or you can bye a couple of the biggest Hard Drive
(with 2.0 USB....I forgot if they are called internal or external...hope I you know what I mean!)  (300GB) an store it into theme.
