For me personally I would always feel more comfortable with backups on a completely different storage technology.
Whilst there are many things you can do with snapshots and replication, there is always a small risk that whatever causes data loss on your primary system may affect/replicate to your 2nd copy. I guess it all really depends on what you are trying to protect against, but Tape still looks very appealing if you want to maintain a completely isolated copy of data. > -----Original Message----- > From: ceph-users [mailto:[email protected]] On Behalf Of > Alexandre DERUMIER > Sent: 06 May 2015 10:10 > To: Götz Reinicke > Cc: ceph-users > Subject: Re: [ceph-users] How to backup hundreds or thousands of TB > > for the moment, you can use snapshot for backup > > https://ceph.com/community/blog/tag/backup/ > > I think that async mirror is on the roadmap > https://wiki.ceph.com/Planning/Blueprints/Hammer/RBD%3A_Mirroring > > > > if you use qemu, you can do qemu full backup.
