Situation

The VMware backup fails at the process of removing snapshot with the error below
[Major] From: VEPALIB_VMWARE@xxx.xxx.xxxx.com "xxxxxx" Time: 3/31/2022 8:14:14 AM
Virtual Machine 'xxxxxxxxxxx': Error removing snapshot

Environment

Data Protector 10

Cause

When Data Protector triggers a VDDK call to flush the memory of a VM, there is a timeout attached to that call.
If you happen to have a large memory size, this default timeout could become too small.

Resolution

Increase the VI_API_TIMEOUT using the following steps:

1. In this instance the leftover VDDK snapshots should be deleted outside of Data Protector manually from the VCenter.
2. After deleting snapshot then please add variable below: Set this variable in the omnirc file of the backup host: VI_API_TIMEOUT=300
3. Save this file and restart INET service on that client.
