Note that CephFS does have one feature that should make efficient incremental backup possible: there is an 'rctime' (recursive ctime) attribute on all directories that will let you skip entire directory trees that haven't seen a modification since the last backup pass. This is a ceph specific feature (nobody else has anything like it that I know of), so I suspect getting it supported in tools like rsync will be challenging, but I suspect a pretty simple tool can be constructed that makes this work and can be composed in a unix-ey way with other tools into a full solution... sage > > There's no generic replication tool for RADOS itself. ?If you're using > librados directly, you'll have to build your own replication system. > > > > On Mon, Aug 4, 2014 at 10:16 AM, Patrick McGarry <patrick at inktank.com> > wrote: > This is probably a question best asked on the ceph-user list. ?I > have > added it here. > > > Best Regards, > > Patrick McGarry > Director Ceph Community || Red Hat > http://ceph.com ?|| ?http://community.redhat.com > @scuttlemonkey || @ceph > > > On Mon, Aug 4, 2014 at 2:17 AM, Santhosh Fernandes > <santhosh.fernandes at gmail.com> wrote: > > Hi all, > > > > Do we have continuous access or remote replication ?feature in > ceph ?
