host-backup

 file-name=

<backup_filename>

 host=

<host_name>

Download a backup of the control domain of the specified XenServer host to the machine that the command is
invoked from, and save it there as a file with the name 

.

While the xe host-backup command will work if executed on the local host (that is, without a
specific hostname specified), do not use it this way. Doing so would fill up the control domain
partition with the backup file. The command should only be used from a remote off-host
machine where you have space to hold the backup file.
