<div dir="ltr">I'm trying to create incremental backups that I could restore when necessary. All backups are being generated fine but I couldn't find a way to recreate an image using all or some of the backup files. For example, my domain is called jammy and is running. jammy-backup.xml: <domainbackup> <incremental></incremental> </domainbackup> jammy-checkpoint.xml <domaincheckpoint> <disks> <disk name="vda" checkpoint="bitmap"/> </disks> </domaincheckpoint> ~# virsh backup-begin jammy jammy-backup.xml jammy-checkpoint.xml * This command with these files generates backup file in /var/lib/libvirt/images appending the checkpoint timestamp in file name (jammy.qcow2 -> jammy.qcow2.TIMESTAMP). ~# virsh checkpoint-list jammy Name Creation Time ----------------------------------------- 1666006874 2022-10-17 08:41:14 -0300 ~# ls -lh /var/lib/libvirt/images -rw-r--r-- 1 libvirt-qemu kvm 2,6G out 18 14:38 jammy.qcow2 -rw------- 1 root root 1,5G out 17 08:41 jammy.qcow2.1666006874 If I create a new domain using jammy.qcow2.1666006874 as disk, everything works good.
