I was also intrigued by the comments of an ADSM system that was managing
50TB of data. So, I went and looked at our configuration and found:
*we manage only 500-G-B of data across multiple platforms with the
server being on MVS mainframe
*our DB (no mirror by the way) is 6.3GB
*our recovery log (no mirror) is 1.7GB
*our DASD backuppool is 17GB
We are still V2 and I know that V3 offers some performance improvements,
but we do have a concern with the fact that managing the ADSM system is
a 24hour process (in other words we don't have a great deal of idle
time) and that we use between 12-20MIPS during our peak daytime period
of 09:00-10:00. The overview of our scheduling is:
*20:00 -> 05:30 is server backup time (at 02:00 we have a copy to our
vault copypool; unload of our DASD backuppool to cart; and incremental
DB backup)
*06:00 -> 08:00 is another copy; unload; DBbackup
*08:00 -> rest of day is the update volume, reclaims, expiration, etc.
It's inconceivable to me that 50TB of data could be managed at
all?????????
