If you have DASD that are as cost effective as tape, have off site mirroring and have software to keep track of and retrieve old versions, then you don't need tape. If you go that way, it's crucial to have all of your ducks in a row before you start changing things. Take a close look at what you're using your current backup software for and ensure that any replacement has the necessary functionality.

First, ML1 & ML2 in HSM, then HSM itself, then rebuild jobs to write to disk, or do SMS/ACS updates to make it all disk reads/writes. Looking at the current storage solutions out there, this is possible, right? What would be the drawbacks (assume that primary storage is super cost-efficient, so there's no need to archive anything). - KB ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
