Note that you can define as many disklist entries on the RAID as you like. On our 560GB unit (backed up to a single AIT1 drive), each user's directory is a disklist entry. When a user goes over 35GB (our data doesn't compress well at all), I tell them to subdivide their stuff and send me the directories they want backed up. Defining a lot of disklist entries like this will save you the administrative overhead of having to reorganize your disklist entries so often as the usage on the RAID grows. > My questions: > Is that a fair summary of my options (as well as #3, buy someone else's > backup software, which isn't an option)?

Thus it will spread out the level 0s for you -- you don't need to worry about it. -- Joshua Baker-LePain Department of Biomedical Engineering Duke University
