S3 backup not retrying after error

[florent]

@Andrew Have you got any retrying writing file message in the logs ?

[Andrew]

@florent No, I did not see that in the logs. I did see this problem is bigger than I thought.

It happens more often than just causing a VM backup failure. It happens during the merge or other checks which causes the backup process to destroy (remove) parts of other VM backups.

 Clean VM directory 
 parent VHD is missing
 parent VHD is missing
 parent VHD is missing
 some VHDs linked to the backup are missing
 some VHDs linked to the backup are missing
 some VHDs linked to the backup are missing

and

 Clean VM directory
