Async Replication?

[Duduhandelman]

Hi All,
Wonder if you have any idea on how to accomplish that.

I will have a KVM running using two drives.
1. OS
2. Database 30TB with no files system

I need to replicate the database to a DR site. the sync should happen once a day ( in order to save bandwidth and I don't need a real time replication ).

I have notice that in 2.3 there is a snapshot capability with Qcow2 format, maybe there is a way to create a snapshot every day and restore it at the DR?

Unfortunately this database does not provide replication option and using a RAW disks without filesystem so Rsync is no good as well.

Will be happy for more ideas..


Thanks you all....

I use DRBD for real time local replication, but not to a DR site.

DRBD proxy might be what you need:

Thanks e100.
It might work but I prefer to load the database after the restore of the snapshot but I think that with drbd I will not be able to do that.

Found this http://kashyapc.wordpress.com/2012/09/14/externaland-live-snapshots-with-libvirt/

Do you think it might work?

Hi,
you can also use lvm-storage for the db-disk and use lvm-snapshot for the rsyncs.
