Hello,


As you probably know, Firebird a) uses complex mechanism to write
consistent data to the database file even in the multi-users
environment, b) intensively uses own cache, which must be synced with
database file.

SafeKit says it is byte-level replication.
So, essentially it is the same as DRBD or shadow or VM-based replication
- the copy of a database locked for the access (even read-only), and
byte-level replication will replicate all low-level errors which occur
in Firebird.
In the best case, the "replica" database will have the same state as
master database after hard-reset.

The true native replication should be logical and transaction-aware.

Regards,
Alexey
