backup-begin Syntax: backup-begin domain [backupxml] [checkpointxml] [--reuse-external] Begin a new backup job. If backupxml is omitted, this defaults to a full backup using a push model to filenames generated by libvirt; supplying XML allows fine-tuning such as requesting an incremental backup relative to an earlier checkpoint, controlling which disks participate or which file‐ names are involved, or requesting the use of a pull model backup. The backup-dumpxml command shows any resulting values assigned by libvirt. For more information on backup XML, see: https://libvirt.org/formatbackup.html If --reuse-external is used it instructs libvirt to reuse temporary and output files provided by the user in backupxml. If checkpointxml is specified, a second file with a top-level element of domaincheckpoint is used to create a simultaneous checkpoint, for doing a later incremental backup relative to the time the backup was created. See checkpoint-create for more details on checkpoints. This command returns as soon as possible, and the backup job runs in the background; the progress of a push model backup can be checked with domjobinfo or by waiting for an event with event (the progress of a pull model backup is under the control of whatever third party connects to the NBD export). The job is ended with domjobabort.
