[ovirt-users] Re: Backup to tape

Hi, Part of our Disaster Recovery Plan we do tape backup. Our previous infrastructure was Oracle VM and VMs fisk were files (.img) we could apply filters to our tar and backup to tape only required files. Now preparing the migration to Oracle flavor of oVirt (OLVM). VMs disks are LVM partitions, within an iSCSI LUNs. I've tested "dd" to backup the entire iSCSI LUN to the tape. Seems OK ,providing the right block size we achieve reasonable performances. Though I don't quite see how to have that granular backup we had, in a simple manner, which a goal too. Although there is compression at the LTO level, the dd conv=sparse parameter may speed-up things. To be tested. I'm just wondering if conv=sparse may breaks things at the LVM / qcow2 containers ? _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/5XPQHPXBANC...
