I have a matter that could require some help.
We have a primary copy on a disk Library, a secondary on another disk Library and a third copy on a MCSS cloud Library. All copies have dedup enabled.
Auxiliary copies run fine between the disk librairies but when it comes to sending the data to the MCSS library it takes forever. We tried to increase the number of streams, use either of the disk libraries as source for the aux copies but we can’t achieve suitable performances. What we see is that the process generate excessive read operations on the source library.
Dedup block size is 128 on the disk libraries and 512 on MCSS.
Commvault version 11.24.
Any help would be appreciated.
