RE: How to Determine Backup Size (Reply from IBM)

This is the reply from IBM:

The following command will show, objects saved, amount of data saved, gigbytes per
hour rate and the volume the data was saved to. Will give you a general idea
of how your saves are performing:
PRTRPTBRM TYPE(*CTLGRPSTAT)

Yes, those numbers do seem to jump all over the place. IDK if it's worth opening up a ticket on it.

From PRTERRLOG:

Volume ---Temporary Errors--- --------M Bytes--------
ID Read Write Read Written
BR0300 0 0 2 5538321
BR0301 0 0 1 2743850
BR0302 0 0 2 5488831
...

From BRMS:

Volume Identifier . . . . . . . . : BR0300
Total Bytes Written . . . . . . . : 5670584
Current Bytes Written . . . . . . : 0
Maximum Bytes Written . . . . . . : 2892360

Volume Identifier . . . . . . . . : BR0301
Total Bytes Written . . . . . . . : 5560780
Current Bytes Written . . . . . . : 0
Maximum Bytes Written . . . . . . : 2809380

Volume Identifier . . . . . . . . : BR0302
Total Bytes Written . . . . . . . : 6273677

I agree that this report shows 'total' bytes written over the life of the
volume. The Display Media Attributes (Work with media, then option 5 next
to a volume) shows Current Bytes Written. However it is not as accurate
as PRTERRLOG.

BRMS says from "creation" date. I don't think you can reset those numbers
(short of removing the volume from inventory).
