Performance issue with GCP backup from snapshot

During GCP backup from snapshot operation the data is read from persistent disks attached to the Snapshot Manager. Persistent disk IOPS speed gets split between disks if read operation is going on multiple disks on the same machine. 

For GCP backup from snapshot operation, a maximum number of 15 jobs can be launched (on machine whose capability is more than 15) and if the capability of the machine is less than 15, then those many backup from snapshot operation can run parallel on Snapshot Manager.

If multiple backup from snapshot jobs are running, then Effective IOPS for single disk = total disk input/output operations per second (IOPS) for read operation on machine/number of disk on which read operation is going on. This results in longer backup times for the VM which have large size when large number of  parallel backup jobs are going on.

Perform the following steps to improve the performance

  1. Select higher configuration for the Snapshot Manager:

    GCP disk IOPS depends on number of factors like VM type, Disk type, Disk size, CPU and so on.

    Select higher configuration to get better IOPS. For more information, see Configure disks to meet performance requirements.

  2. Limit the number of jobs running on Snapshot Manager:

    Use the following settings to limit the number of parallel jobs running on Snapshot Manager:

    [capability_limit]

    max_backup_jobs = 4

    If Snapshot Manager machines capability is less than max_backup_jobs then machines capability would be considered. If machines capability is more than max_backup_jobs then value of max_backup_jobs would be used to decide the number of backup from snapshot jobs to be run on machine. After changing the configuration restart the Snapshot Manager and complete manual discovery on NetBackup.
