We have started seeing these errors since the upgrade to 6.5 (not before) and no other upgrades/changes other than the upgrade.
We receive this error primarily while backing up one VM, yet it shares the same SAN/iSCSI network as all of our 3 hosts and the frequency is never more than once per day, 4-5 days out of 7.
All backup sets are using SAN and other than this periodic issue, everything else works normally and test restores before/after this error show no problems. Veeam is installed withing a VM and the host and SAN are connected via dedicated gigabit switch for all iSCSI traffic with 6 ports on the SAN and 4 each per host. No other indications of network issues.
The specific error we receive is:
- Code: Select all
Error: Client error: End of file Unable to retrieve next block transmission command. Number of already processed blocks: 
If anyone has any suggestions on what else to check/how to track this further.
