Thanks for your answers everyone. The data is fairly stable, and would definitely fit with a differential regime (rather than incremental).

But what's the change rate on that data? I find that in many orgs, a lot of data is quiescent. In other words, files which have been written and are not going to change again, or will not do so any time soon. Such files can be backed up once separately, e.g., to an archive tape (or multiple tapes), and then you can exclude them from the regular backup set. Of course, handling the above requires more intelligence than NTBACKUP provides. I don't think most of the cheaper commercial products can do anything about it, either. -- Ben ~ Upgrade to Next Generation Antispam/Antivirus with Ninja! ~ ~ <http://www.sunbelt-software.com/SunbeltMessagingNinja.cfm> ~ Internet communications are not secure and therefore Leonard Cheshire Disability does not accept any liability for the content of this message.
