I assume that in this scenario there is only one user/file of huge size and all the other users/files are much smaller (in other case, there will be not much difference in distribution among drives). But the suggested backup/recovery approach can work even in this scenario. If we have a configurable value that specifies maximum number of backups/versions, then in a setup where such a use case is possible, the max_file_backups value may be set to disallow backups at all (by default backups can be disabled). In other case, when OpenStack is used as a backend for let's say text documents, backups can be enabled and another cloud provider might benefit from this feature. - Rostik _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
