I doubt that we are unique in being legally required to keep 'some data' for the life of the corporation. Even if it's not a substantial percentage of the total, it's non-trivial and means that forever you will need to add more and more acreage to the DASD farm even if your 'live data' needs remain static--an unoptimistic forecast at best. I understand the short-term appeal of eliminating an entire peripheral component. I also understand the long-term agony of being required by a judge to cough up data that you can no longer retrieve. The rosy take is that your head will plop in the guillotine basket alongside your CEO's. ;-) . .

The device is a little DASD farm on the inside and our BACKUPs and MIGRATION datasets are super-fast to retrieve Expansion on point 2: You may need more DASD than you did TAPE. I think with TAPE the BACKUP datasets are stacked. When you write to DASD - I think they become individual dataset and may require more room Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] > On Behalf Of Lizette Koehler > Sent: Tuesday, May 30, 2017 11:11 AM > To: IBM-MAIN@LISTSERV.UA.EDU > Subject: Re: HSM Backup to Disk > > So my thoughts are > > 1) Yes you can do this > 2) You may need more dasd that tape > 3) You will be tying up DASD for a long time for backups. > 4) You will need to determine how long your longest Backup dataset > is held for. > > An HSM Backup is used to recover files.
