Re: [ovirt-users] The future of backups in oVirt 4.2+

If you are using NFS, you might find it easier and more efficient to use a solution outside oVirt. I've documented an initial attempt at backing up machine images with backy2 at https://dyasny.blogspot.ca/2017/06/exploring-backup-optio ns-for-rhvovirt.html It is harder to do with block storage and frankly I haven't had the time to get to doing it there, but NFS is simple enough, and what you get is pretty robust, deduplicated backup, in some ways similar to the typical VM backups you get from Veeam and Altaro on other platforms (sans the GUI of course).
