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).
