Flashbackup snapshot error 156

Hello everybody,

 

I would like to ask for a suggestion regarding windows flashbackup backups and restores.

I have to backup and restore a system with a millions of little files (this is a characteristic of the application running on the server).

Description of the enviroment:

1 Mastar / Media server Redhat

1 media server Redhat

1 Windows server Client with 3 disk volume drive units which the size every unit is 3TB

Backup type: Windows Flashbackup 

 

The backups have been working successfuly until the April 22th.  The april 23th the server stops because storage problems. I found that one of the volume drive is up to 99% (20 GB free space of 2.99 TB).

When I run the backup i got the error 156 snapshot error. I found out the technote NetBackup VSS snapshot error encountered (156) at https://support.symantec.com/en_US/article.TECH75214.html.

I took the full volume drive off from the backup selection and the backup works without that volume.

I have been asked to thake the backup from that volume before purge or move the information. Then I created another policy only with the full volumne drive in order to thake the backup but i still gettin the 156 error.

Does any body have suggestions to this problem?

 

Best regards

 

 

 

 

 

 

  • Unfortunately we have to rely on VSS to perform the backup. You can try and move the shadowstorage area for the failing drive to another using vssadmin

     

    vssadmin add shadowstorage /for=<ForVolumeSpec> /on=<OnVolumeSpec> [/maxsize=<MaxSizeSpec>]
