Description
- Hyper-V backup fails with error: "VSS error 0x800423f4: The writer experienced a non-transient error. If the backup process is retried, the error is likely to reoccur."
Environment
- Cove Data Protection (Cove)
Solution
- Open Hyper-V Manager
- Open Hyper-V host and select virtual machine causing error
- The file path on the backup session can show the VM that is causing the error
- Right-click Virtual Machine > Settings > Management tab > Integration services
- Disable Backup (volume snapshot) Service
- Click OK
- The machine will be in 'saved' state for a short period of time when you're not using 'Backup (volume checkpoint)' option and the uptime counter could be reset
- To run the backup with this option enabled, check eventlog on the Hyper-V host - it will contain warnings/errors pointing to the particular machine causing the issue
- You will need to check the eventlog inside of VM(s) specified and implement corresponding fix to resolve the issue
- If the issue persists modify the
config.ini
located inC:\Program Files\Backup Manager
by default. Add the following lines to the bottom:[HyperV]
UseSnapshotLimitsOnBackup=0
LimitSnapshotComponentsCount=0 - Save the
config.ini
file - Restart the Backup Service Controller Service for changes to take effect
