Dear Sir,
I use dirty bitmap to backup kvm raw images. I did not shutdown or suspend the vm when
backup.
I try to export backup as raw images or qcow2 images when doing full backups as the
origin disk is in raw format, all backup jobs finish successfully. But only the raw images
works, the guest os runs well. The qcow2 backup has data corruption and the guest os is
in rescue mode.This happens all the time and no operation is done to the vm when doing
backup.
export as raw disk
{ "type": "drive-backup", "data": {"device":
"drive-virtio-disk0", "target":
"/datastore/centos.raw","sync":"full" ,"format":
"raw"}}
export as qcow2 disk
{ "type": "drive-backup", "data": {"device":
"drive-virtio-disk0", "target":
"/datastore/centos.raw","sync":"full" ,"format":
"qcow2"}}
After I suspend the vm, and export qcow2 disk, the disk works.
Are there any limits when using bitmap to backup raw disks? For example , we should keep
the backup disk in the same format as the origin when vm is running?
