As part of the scheduling options, you can configure a duration or time window when consistency

checks jobs can run. For example, you can configure the consistency check to begin at 8:00 P.M.

when most of your company’s employees are gone, with a maximum duration of 10 hours.

Creating Replicas Manually

When you create a protection group, you can choose to create the replicas manually from tape or

other removable media to reduce the load on the protected computers and network.

Automatic replica creation is easier; however, depending on the size of the protected data,

manual replica creation can be faster. For smaller data sets, we recommend the automatic

option. For large data sets and slow networks, the manual option is likely to be a better choice.

After the replica is created, you must run synchronization with consistency check.

Increasing Capacity

You can also improve performance by increasing the capacity of the DPM server through

hardware upgrades:

• Adding disks to the storage pool and reallocating the replicas across the storage pool can

help reduce disk queue length.

• Using striped volumes can increase disk throughput to deal with disk bottlenecks.

• Adding memory is a relatively inexpensive upgrade that can result in a noticeable

improvement in performance if the server frequently experiences low available memory.

• Adding more processors or upgrading to faster processors can reduce CPU issues.

Also, consider your data protection requirements: you might need additional DPM servers to

balance the workload.
