Ok I'm pushing and try to keep it to mailing list :-) On lundi, 9 janvier 2017 12.31:13 h CET Robert N wrote: > let me see if I get this right. do you meand I should be using spooling for > the backup to disk jobs, and copy jobs from disk volumes to tapes without > spooling? >
I was addressing only one type of backup, several jobs running concurrently spooled, then merge in one device (disk based) (one or splitted by size volumes). Not playing enough with tapes, I can't say anything on the second part (copy/ migrate) to tapes. But then you are reading one device and writing to another one, the slowest making the io bandwidth. It seems from what is expressed on the mailing list, that copy/migrate with jobs are failing in a one after the other syndrom.
