friends i am using veeam B&R for backip up my VMs and my infra is very beefed up IBM servers which are getting backed up on a storage device .. but my jobs are failing .. it hass never happened that my job gets completed properly .. things like .. VMs restarting, VMs getting berry slow, VM backup error - VSS writer fatal error etc.
i check with Veeam engineer with a case and after his 10 days research he said its Msoft issue and i should knoe their doors. below are few errors which i get when backup job failed for VMs... there is nothing common in VMs failing .. any random VM fails...
1. VSS writers inside virtual machine 'CLIENT VM' failed to perform BackupComplete to its shadow copy (VSS snapshot) set: A function call was made when the object was in an incorrect state for that function (0x80042301). (Virtual machine ID 20A3EAB9-89A6-4BC9-8AA5-96AAE3956610)
2. Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
Failed to create snapshot (Microsoft CSV Shadow Copy Provider) (mode: Crash consistent) Details: Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
Error: Guest processing skipped (check guest OS VSS state and hypervisor integration components version)
MY all VMs have updated integration components.
3. this is very frequent: Failed to create snapshot (Microsoft CSV Shadow Copy Provider) (mode: Veeam application-aware processing) Details: Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_FREEZE'. The writer's
timeout expired between the Freeze and Thaw events. --tr:Failed to verify writers state. --tr:Failed to perform pre-backup tasks.
Retrying snapshot creation attempt (Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_FREEZE'. The writer's timeout expired between the Freeze and Thaw events. --tr:Failed to verify writers state. --tr:Failed to perform pre-backup tasks.)
Queued for processing at 12/16/2016 3:40:31 AM
Task has been rescheduled
Unable to allocate processing resources. Error: Writer 'Microsoft Hyper-V VSS Writer' is failed at 'VSS_WS_FAILED_AT_FREEZE'. The writer's timeout expired between the Freeze and Thaw events. --tr:Failed to verify writers state. --tr:Failed to perform pre-backup
tasks.
not sure what to do and what not .. VSS writers are checked by Veeam engineer on host as well as VMs and as per him all are fine.
guys can you help as VMs getting down is really creating issues for me.
Thanks, Happiness Always
