Hi, experts,
 
       We have two questions about  object storage.  Customer wants a flexible replication policy , eg. doesn't want replicate object synchronous to another Grid , but want to replicate at setting time ( eg.  at night idle time), Does CGR has such flexibility ?  Or how can achieve this purpose ?
       2nd question is if customer wants to migrate data from Ceph based object storage to SG ,  which tool is a better choice ?
