CSV Timeout in Minutes configuration parameter
This topic pertains to NetBackup for Hyper-V.
The CSV Timeout in Minutes configuration parameter applies to backups of the virtual machines that are configured in a Microsoft Cluster that uses cluster shared volumes (CSV). The timeout determines how long the backup job waits, in case another cluster node backs up the same shared volume at the same time.
The default is 0 (no wait). If you do not want NetBackup to wait for another backup to release the shared volume, accept the default. If at the same time another cluster node backs up a shared volume that this backup requires, the backup fails with status 156.
The appropriate value for this timeout parameter depends on the following factors:
The average backup job duration for the virtual machines that reside on the same CSV. The duration depends on the size of the virtual machines and the I/O speed.
The number of virtual machines on the same CSV.
More information is available on NetBackup support for the virtual machines that use CSVs.
