In the past I've used scripts to perform a high/low watermark based clean up on the Disk because once the first clone to offsite tape is performed, I just want to keep data on the adv_file Disk for as long as possible without needing additional tapes to stage to... now why can't we just set the "Staging" jobs to simply delete the oldest savesets instead of staging to tapes we don't want and subsequently manually recycle? Any suggestions for a more elegant solution?

Unfortunately you still need to mark those savesets as suspect to get a working restore from the onsite clone :( After a week of tearing my hair out and a support case with EMC, they have told me that the networker module for oracle doesn’t recognise the offsite flag and will always try for the set with the lowest cloneid.
