Vladimir Rodionov commented on HBASE-16181:
-------------------------------------------

[~mbertozzi], we need snapshots for hbase:backup table to implement fault 
tolerance during backup procedure. Before backup starts we snapshot 
hbase:backup. If backup fails, we clean up all files/dirs and restore 
hbase:backup from snapshot.

> Snapshot of HBase system tables is not supported, we need either move 
> hbase:backup into different name space or fix snapshots.
