Sekar In my old mainframe days the practise was to copy tapes after a year. I've not seen anything about more modern media, but I'm inclined to run a job once a month to to a move data on any tape that hasn't been used for some defined period, be it one year or two or three. This ensures that the data is readable and that the source tape is physically located once in a while.

To quote live example, Iam getting around 3MB/s for various backup/archieve which runs over fairly long period of 30 minutes. I have had 1 GB backedup and restored in less than 8 minutes when the restore was for a single file ( we do have many of them hitting the ceiling of even excess of 20 GB, I havent tried them yet!!). The environment on swithced ethernet LAN of 100 Mbs, AIX /IBM 43P server and clients on various platforms, backuppool of just 500 MB and migration /spillover pool on IBM 7331-305 with Mammoth 20 GB exabyte catridge. ( incidentally can any one answer on shelf life of Mammoth 20 GB catridges.. The predecessor 5/7 GB exabyte where very poor on long time retention, i have read like something less than 3 years) hope info is useful sekar narasimhan ONGC, Chennai, India mail - [EMAIL PROTECTED] --- Louis Wiesemann <[EMAIL PROTECTED]> wrote: > I'm just looking for any guesstimates anyone might > have for the throughput we might "expect" to see > restoring a Netware 3.1.08 client with a TSM 3.7.3.0 > OS/390 server.
