Vmbackdir
The vmbackdir option specifies the temporary disk location where the client saves control files that are created during full VM backup and restore operations of virtual machines.
Supported Data Movers
This feature is available only if the client operates as a data mover for IBM Spectrum Protect™ for Virtual Environments.
When a client on a data mover node starts a full VM backup of a virtual machine, the client creates metadata in files that are associated with the backed up virtual machine and its data. The files that contain the metadata are referred to as control files.
During full VM backup operations, the metadata is saved on a disk in the data mover node until the backup completes and both the virtual machine data and the control files are saved to server storage. During a full VM restore operation, the control files are copied from the server and are temporarily stored on the data mover disk, where they are used to restore the virtual machine and its data. After a backup or a restore operation completes, the control files are no longer needed and the client deletes them from their temporary disk location.
The directory that is specified by this option must be on a drive that contains sufficient free space to contain the control information from a full VM backup.
This option is valid for Linux and Windows data movers that are installed on a vStorage backup server.
This option is valid for Windows data movers that are installed on a Hyper-V server.
Options File
Set this option in the client options file, or specify it on the command line as an option for the backup vm or restore vm commands.
