## Creating the replica database ## Creating the replica database
In the Beta 1 release, any physical copying method can be used: Any physical copying method can be used on the primary host:
* File-level copy when Firebird server is shutdown * File-level copy when Firebird server is shutdown
* ALTER DATABASE BEGIN BACKUP + file-level copy + ALTER DATABASE END BACKUP * ALTER DATABASE BEGIN BACKUP + file-level copy + ALTER DATABASE END BACKUP
* nbackup -l + file-level copy + nbackup -n * nbackup -l + file-level copy + nbackup -n
* nbackup -b 0 * nbackup -b 0
If _nbackup_ was used, restore or fixup operation should be performed to complete the replica creation. Note that if you're recreating a priorly working replica, then `-seq[uence]` option of _nbackup_ must be used to preserve the replication sequence counter inside the database, so that replication could continue from the moment when the primary database was copied:
* nbackup -f <databasw> -seq
Then the replica mode must be activated for the database copy. Two options are possible: Then the replica mode must be activated for the database copy. Two options are possible:
* gfix -replica read\_only <database> -- set up database as read-only replica * gfix -replica read\_only <database> -- set up database as read-only replica
