It would be nice, if ovirt snapshots were more safe. When a VM has
the ovirt-agent installed, ovirt could tell the agent to run
site-speficic actions. What I have in mind is:<br>
<br>
linux vms:<br>
- sync<br>
- echo 3 > /proc/sys/vm/drop_caches<br>
- zerofill empty space (this takes long but saves precious backup
space)<br>
<br>
databases:<br>
- prepare databases for snapshot (flush,write-lock)<br>
- send snapshot-complete and unlock<br>
