my backup is stable for the past month and i would like to enable compression for the backup to disc jobs.
For most normal backup2disc jobs (Hyper-V, Exchange, SQL) the job rate ist about 28-34GB/min.
If i enable compression for the same job, it slows down to 4-5GB/min.
Where is the bottleneck, is it the Host or the Client System?
Is there any option for tuning the compression method or the number of CPU´s that are used for compression?
i verified the Backup Server and the Host.
During compressed, encrypted or normal Backup both Servers show no sign of CPU load, Memory load.
During compressed backup i see that the disk read/write operations is very low 120MB/s (read) ; 120 MB/s (write).
During normal backup i see that the disk read/write operations is high 650MB/s (read) ; 650 MB/s (write).
Is Veritas using only a single CPU?
What can be changed in Registry for BE ?
