Hi, I guess that's a question that pops up in different places, but I could not find any which fits to my thoughts. Currently we start to use ceph for file shares of our films produced by our students and some xen/vmware VMs. Thd VM data is already backed up; the fils original footage is stored in other places. We start with some 100TB rbd and mount smb/NFS shares from the clients. May be we look into ceph fs soon. The question is: How would someone handle a backup of 100 TB data? Rsyncing that to an other system or having a commercial backup solution looks not that good e.g. regarding the price. One thought is, is there some sort of best practice in the ceph world e.g. replicating to an other physical independent cluster? Or use more replicas, odds, nodes and do snapshots in one cluster? Having productive data and backup on the same hardware currently makes me feel not that good too….But the world changes :) Long story short: How do you do backup hundreds of TB? Curious for suggestions and thoughts .. Thanks and Regards .
