VOVM0002: When Backing Up Multiple VMs, Backups Fail for Some VMs

Symptom

A backup job that includes multiple VMs and uses multiple data readers might not be able to complete backups for some VMs.

Cause

If the backup cannot take a snapshot of virtual machine data immediately, the snapshot operation might time out and cause the backup for that VM to fail.

Resolution

To avoid this issue, you can increase the number of snapshot retries and the retry interval by creating the nCreateSnapshotRetryAttempts and nCreateSnapshotRetryIntervalSecs additional settings on the VSA proxy.

Property

Value

Name

nCreateSnapshotRetryAttempts

Category

VirtualServer

Type

Integer

Value

Increase the value and retry the backup. For example, increase the number of retry attempts in increments of two until the backup is successful.

Property

Value

Name

nCreateSnapshotRetryIntervalSecs

Category

VirtualServer

Type

Integer

Value

Increase the value and retry the backup. For example, increase the interval in increments of 15 seconds until the backup is successful.
