[jira] [Created] (OAK-1159) Backup and restore

Michael Marth created OAK-1159:
----------------------------------

             Summary: Backup and restore
                 Key: OAK-1159
                 URL: https://issues.apache.org/jira/browse/OAK-1159
             Project: Jackrabbit Oak
          Issue Type: New Feature
            Reporter: Michael Marth


We need a way to backup and restore a repository. I was thinking that the MK impl could expose an interface for this, as the actual implementation would differ quite a bit between e.g. TarMK and MongoMK.

Also, I think we could leverage the MVCC nature of the MKs and mark a  specific revision as "the revision to backup" (regardless of ongoing writes). That would allow us to prevent the ugly situation in JR2, that we need to stop writes for a while to produce a consistent backup.

The restore in such a scenario would discard revisions that happened after said marker (but still made it into the backup).
