Hi,
I have a client who uses Windows Server Backup on a Server 2008 R2 installation. I have set up their backup to remote share on another server. Both servers seem to be fine but when the backup starts I get the error "The device is not ready".
Going through the event logs I found errors during the time of the backup:
Event ID 129. Source vhdmp - description for event id 129 cannot be found. The following information was included with the event: \Device\RaidPort1
Event ID 57. Source Ntfrs - The system failed to flush data to the transaction log. Corruption may occur.
Event ID 15. Source Disk - The device \Device\HardDisk1\DR4, is not ready for access yet.
(the above HardDisk1 doesn't exist. the server only has a single hard drive in it so I am not sure what this error is referring to)
Event ID 3. Source FilterManager - Filter Manager failed to attach to volume '\Device\HarddiskVolume6'. This volume will be unavailable for filtering until a reboot. The final status was 0xc03a001c.
Going through the Windows Backup event log I see the error below:
The backup operation that started at '2013-08-04T10:00:06.701517900Z' has failed with following error code '2155348041'
I had a search around and found the log files in C:\Windows\Logs\WindowsServerBackup. In the log files I see the error:
Error in backup of C:\tempsys\audit\WD123.zip.0183 during write: Error [0x800700a1] The specified path is invalid.
This error occurs multiple times and refers to many different files and folders.
I have noticed that if I stop the backup schedule and delete the backup files then recreate the backup job the backup will run successfully for a night and then fail on subsequent backups. Because of this it doesn't seem like it is a hardware issue or else it would fail even after recreating the backup job.
I have searched the forums and found nothing that relates to my issue. the server is not a Hyper-V host or VM. Neither Backup Exec or AV are installed on the server. I have gone through the files/folders randomly and checked that the backup user has permissions on the files - they have all checked out fine. I am not backing up the System drive, just a folder on the C drive.
I am really at a loss to explain what is causing this and any help would be greatly appreciated.
Thanks
