> Concurrent backup / restore support
> -----------------------------------
>
> Key: HBASE-16579
> URL: https://issues.apache.org/jira/browse/HBASE-16579
> Project: HBase
> Issue Type: Improvement
> Reporter: Ted Yu
> Labels: backup
>
> Currently we take exclusive lock on hbase:backup table in backup / restore procedures.
> There is only one backup or restore operation which can run at given time.
> We should consider using shared lock on hbase:backup table in the procedures so that concurrent backup / restore operations can proceed.
> The concurrency is useful when table sets don't overlap.
> We may devise other mechanism(s) when there is overlap among the table sets.
