Bruce, that would be true but Sam used the FCNOCOPY option. Using this option in DSS, only the T0 (time 0) tracks that were updated on the source volume are copied to the target. This assumes FLASHCOPY V2 is used. Once the target volume is dumped and the FC withdraw is done, the data on the target is basically 'junk'. The default (no FCNOCOPY keyword specified) will perform the background copy and the data can be used as is; i.e. dumped to tape, used in a testing environment, updated, deleted, etc. Bruce Estey ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
