Symptoms

Avamar Image backup or restore jobs are failing/slow due to SnapShotManager operations.

Cause

Background on the SnapShotManager service:  

The SnapshotManager is a web service that operates on the Avamar server. During backup or restore operations, when the Avamar proxy performs a snapshot operation (create, delete, or consolidate), it uses SnapshotManager service. This approach centralizes snapshot operations, allowing them to be queued on the Avamar server instead of vCenter. However, this centralized model introduces a potential bottleneck and service dependency, which may require disabling to address backup or restore issues.

To check the SnapshotManager status, follow these steps:

 If SnapshotManager is enabled, the image backup log displays the following information: 
avvcbimage Info <42215>: SnapshotManager: initializing at Avamarserver:443, vCenter vc6-avamar.example.com(root), datacenter(/Burlington), httpsTimeout_ms(3600000), maxDeleteRetries(-1)
avvcbimage Info <42191>: GET: curl_easy_getinfo succeeded with httpcode(200)
avvcbimage Info <44033>: AvSnapMgr::getData Succeeded httpCode: 200


 If SnapshotManager is disabled, the image backup log shows: 
 avvcbimage Info <40643>: NOT using SnapShot Manager - using proxy method of calling vSphere API functions.
 avvcbimage Info <18648>: The snapshot '' could not be removed.

Resolution

Long-term Solution:
This issue will be addressed in a future Avamar release. In future versions of Avamar, the Avamar proxy will not use SnapshotManager service.
 

How to Disable Snapshot Manager in Current Release:

To disable the SnapshotManager service, modify the proxy's avvcbimageAll.cmd using one of these two methods:
