Symptoms

Transparent Snapshot Data Mover (TSDM) VM backup fails with either of the errors below: Observed when ESXi is upgraded to 8.0.2 but vCenter is on 8.0.1. ERROR ONE: The vCenter task failed: A specified parameter was not correct: sync id (500) BackupVMSession log example: 2023-10-05T13:28:32.712Z DEBUG: [b2cddd69bf2b2a3f;96fe2fd32rrr65e0] SDM Data Mover: SDM Delta Sync: Set VM Cleanup Descriptor. 2023-10-05T13:28:32.777Z ERROR: [b2c5gghhbf2b2a3f;96fe2fdttt7465e0] SDM Data Mover: SDM Delta Sync: The vCenter task failed: A specified parameter was not correct: sync Id 2023-10-05T13:28:32.777Z ERROR: [b2c50bfff2b2a3f;96fe2fd32f65e0] SDM Data Mover: SDM Delta Sync: The vCenter task for 'SDM Snapshot Sync deltaSync' completed with state 'error'.

Cause

PowerProtect Data Manager engineering conducted interoperability tests regarding TSDM in VMware versions 8.0.1 <-> 8.0.2. Here are the results: ESXi 8.0.1 <-> Center 8.0.1 works fineESXi 8.0.2 <-> Center 8.0.1 fails with the error "The vCenter task for 'SDM Snapshot Sync Full' completed with state 'error'. The vCenter task failed: A specified parameter was not correct: sync Id (500)"ESXi 8.0.2 <-> Center 8.0.2 works fineESXi 8.0.1 <-> Center 8.0.2 fails with error "vCenter task 'task-72158' failed: VimFault: 'dp.vpx.fault.SnapshotInProgress.summary': DPD Snapshot in progress, TSDM snapshot UUID = '45e3b245-34fb-4d30-adf6-e01f27dc3aaa' (500)"

Resolution

As vCenter and ESXi upgrades and versions are outside the bounds of PowerProtect Data Manager, it is up to the customer how to proceed. Upgrade so both vCenter and ESXi are on version 8.0.2 Or Downgrade so both vCenter and ESXi are on version 8.0.1 PowerProtect Data Manager does not support version 8.0.2 as of October 2023.
