Parallel Processing

You will get the below screen:

Parallel Processing

Below two concurrent backup parameters could be set:

Option 1: Maximum number of concurrent backup tasks in the BDRSuite Backup Server

  • Simply put – this parameter specifies the maximum number of backup tasks that your BDRSuite Backup Server can handle at a time
  • You can set this upto a value of 999
  • As an IT administrator, you can set this value, entirely based on your existing system resources – CPU and Memory
  • For example, if you are setting this value to 100 based on your system resources, the backup server can handle a maximum of 100 backup tasks concurrently

Option 2: Maximum number of concurrent tasks per backup job

  • In Simple terms – this parameter determines the max number of backup tasks that an individual backup job can handle concurrently
  • This comes in handy when you have 100s of Virtual Machines/disks to be backed up inside a cluster (VMware ESXi or Hyper-V) or multiple physical windows machines and you don’t want to go with the usual serial processing (taking backups one by one)
  • This is a granular setting, where you have the privilege to set any value from 1-99
  • This value has to be set lesser than the maximum concurrent tasks the backup server can handle (which was set using Option 1)
  • The Total number of Backup jobs that can run simultaneously is determined by dividing Option 1 / Option 2. For example,

    • Parallel Processing

  • This will definitely save a lot of time, by efficient utilization of your existing system resources

A Note on System resource utilization

  • BDRSuite recommends a minimum of 8 GB RAM with a Quad core processor for BDRSuite Backup Server deployment
  • Normally, 4 GB RAM will be utilized to run the BDRSuite Backup Server and database services
  • We recommend considering approximately 500 MB RAM for each active backup task. For example, if you want to run 8 concurrent backup tasks in your BDRSuite Backup Server, you would need to ensure you have an additional 4 GB to accommodate those backup tasks
  • To avoid significant CPU usage during active backup progress, the BDRSuite Backup Server machine should be assigned with enough CPUs/vCPUs
  • Normally, one vCPU can handle approx 8 concurrent backup operations like read/write
