I implemented a bash script which is backing up my VMs. Basically I am doing the following steps:
- Create a snapshot of the target VM
- Backup the disk of the target VM
- Merge the changes back to the disk
Now I tested the backups and noticed, that the disks of the machines are not fully consistent. The Windows machine is starting with a chkdisk and recovers some files. I understand that this is especially the case, if step 1 happens during a write.
However, all backups done so far, are booting but I am afraid that there are cases where the backup won't boot.
I am especially worried about the windows machines.
Are these worries justified?
Thank you in advance!
