ephemeral storage backup

Hi,

Are there any scripts or ideas to take nightly snapshots of ephemeral disks to ceph (or swift)

Ideally they would be incremental but I guess that would be impossible.

Just in case a compute node gets corrupted etc.

Thanks

Daniel

ok let me rephrase nightly snapshot to volume backups in cinder or glance?

Ephemeral will be much faster than ceph hence the reason for ephemeral

Ephemeral is ephemeral... and snapshots shouldn't be considered backups. You are probably better off redesigning your applications and use block storage instead and make sure that snapshots are enough for your use case.
